Profiled membranes instead of concrete preparation. Planter membranes for drainage and insulation protection: material selection and installation technique. Planter for foundation. The use of a membrane as a replacement for foundation preparation

The construction of a foundation inevitably requires preparation of the soil base, which consists of leveling the surface, excavating the soil, preparing the bottom of the pit and creating a capillary cutoff. In the 1980s, in the rules for preparing the foundation for building foundations, a recommendation appeared on the installation of concrete preparation on the foundation soil.

The task of concrete preparation: obtaining a flat and durable base surface for installing reinforcement, as well as preventing the mixing of the lower layer concrete mixture with foundation soil. Usually it is made of low-grade concrete (class B 7.5) 8-10 cm thick over a compacted crushed stone or sand leveling layer. This concrete preparation is not included in the calculations of the bearing capacity of the foundation.

Traditional design

When constructing the foundation in sandy soils With low level groundwater(below the bottom of the pit), there is no direct need to protect the slab in the form of waterproofing; it is necessary to protect only from capillary moisture. In this case, you can refuse to use concrete preparation (since no waterproofing work will be carried out), and use standard instead.

Design with profiled membrane PLANTER

In comparison with the polyethylene film used for the described purposes with smooth surface, the PLANTER profiled membrane has the following advantages:

1. Due to the textured surface, the profiled membrane is securely fixed into the sand base without deforming or moving during installation.
2. Fixed into a sand base, the profiled membrane provides a solid surface suitable for grading and concrete placement.
3. The surface of the membranes can withstand the movement of workers and machines for transporting concrete mixtures and solutions (excluding crawler-mounted machines) without breaking.
4. The service life of the PLANTER profiled membrane is more than 60 years.

Base structure
under a slab foundation and a floor on the ground

The technology of work when replacing concrete preparation with a PLANTER standard membrane in the general case is as follows:

• digging a pit to the required depth, removing soils susceptible to frost heaving;
• performing a well-compacted sand leveling preparation with a thickness of at least 5 cm, allowing the membrane spikes to be fixed;
• laying the profiled PLANTER membrane with the spikes facing down. The seams between the overlapping rolls are carefully taped.

When assembling membrane elements, the sheets are interconnected along the length and width, overlapping with at least four rows of spikes (protrusions) overlapping. To connect the sheets, the joints must be coated with adhesive mastic or self-adhesive tape (or). The end rolls of the profiled membrane are attached to each other at intervals with a minimum distance of 50 cm.

When carrying out work to replace concrete preparation using a profiled membrane, the following factors must be taken into account:

• the reinforcement cannot be welded - it only needs to be knitted;
• reinforcement cages must be installed on plastic embedded elements;
• the lower protective layer of concrete to the lower reinforcement must be at least 25 mm.

The use of profiled membranes creates optimal conditions for hardening concrete, because the liquid component of the concrete mixture does not go into the ground. The studded surface of the membrane gives it the necessary rigidity, which makes it possible to lay a reinforcement cage directly on it, install formwork and concrete.

This technology allows you to: protect monolithic reinforced concrete structures and structures from capillary moisture, ensure high rates of work (2000-3000 m2/shift), reduce the time period for preparation, and significantly reduce the labor intensity of work.

Fragility of the deposited bitumen waterproofing, especially under aggressive conditions groundwater, ultraviolet radiation or mechanical influences is a known problem for most builders. Therefore, the issue of protecting the waterproofing of the foundation and roof is relevant. ABOUT modern methods And existing materials“Stroyka” learned from specialists.

Several dozen professionals gathered at the same time to talk about new materials and methods of their use within the framework of the seminar “Design and Construction of Underground Structures”, which was held recently in Minsk. Among them are both direct manufacturers and representatives of the largest foreign corporations in Belarus, heads of scientific departments, and technical consultants.

Manufacturers presented at the seminar relatively new for the Belarusian construction market technical solutions stated tasks. We are talking about profiled membranes, the range of which on the market is becoming wider every day: Tefond, Planter, Isostud, Delta, Villadrain - this is an incomplete list of brands under which the materials are produced.

What is what

The profiled membrane is a sheet of polyethylene high density(PVP) with protrusions molded on the surface (usually spherical or in the shape of a truncated cone) with a height of 7 to 20 mm. Material is produced with a density from 400 to 1000 g/m2 and is supplied in rolls with a width of 0.5 to 3.0 m and a length of 20 m.

The main functions of membranes are to protect waterproofing layers and organize water drainage. The air gap, which is formed between the protected surface and the membrane due to profiled protrusions on the surface of the membrane, provides a drainage effect and protection of the foundation waterproofing, and prevents the formation and loss of condensation inside the insulated premises.

Membranes can be installed both vertically and horizontally. They are welded together with hot air, glued together with a special connecting tape or connected into a lock.

Areas of use

The main tasks for which membranes are intended: replacement of concrete preparation, protection of waterproofing of foundations, arrangement of drainage of a foundation or used roof, arrangement of waterproofing of tunnels and subways. Related: construction of “walls in the ground”, rehabilitation of damp walls outside and inside the premises.

Replacement of concrete preparation

Concrete preparation - mandatory stage in the construction of any building, usually carried out by pouring lean concrete 100 mm thick over compacted soil. If a building is being erected on soil with a low groundwater level and in the absence of water pressure, the use of membranes is an alternative to concrete preparation.

The use of membranes allows you to reduce the time of work and reduce their cost, protect the foundation slab and increase the service life of the system.

Foundation waterproofing protection

As builders note, the greatest danger for waterproofing foundations is the period of the zero cycle before backfilling, since the waterproofing layer is not protected from the destructive effects of ultraviolet radiation, but most importantly - mechanical influences. There is also a high risk of damage to the waterproofing layer by construction waste, which abounds in the backfill soil. During operation, waterproofing can also be exposed to aggressive chemical effects of groundwater, which will negatively affect its service life.

Among existing options protection - heavy and expensive flat slate or Brick wall, the arrangement of which is an even more labor-intensive and expensive process.

Developers call membranes an alternative, which differ high speed and ease of work on waterproofing the foundation and low cost. The membrane is rolled out with protrusions towards the foundation, thereby forming an air gap between the soil and the waterproofing. Local loads created by the soil are evenly distributed over the entire area, which avoids local damage to the waterproofing layer. Polyethylene is chemically resistant material and protects waterproofing from the negative effects of aggressive soils.

Waterproofing and drainage systems for foundations and existing roofs

One of the main elements of the foundation waterproofing system is drainage, which helps remove water from the structure. In an existing roof, the drainage layer performs a similar function, removing water from roofing pie. In both cases, drainage avoids water pressure on the waterproofing layer and, as a result, insulation breaks, water penetration and structural damage.

When waterproofing the foundation, membranes are used as vertical wall drainage - the membrane (it is recommended to use the option with geotextile) filters water and quickly removes it into the drainage pipe. In this case, the role of the filter element, for which sand was previously used, is played by the geotextile membrane. Therefore, you can refuse to use sand and immediately move on to backfilling the soil.

When constructing roofs, a membrane with geotextile is laid under a sand backfill. Geotextiles serve as a filter element, and the membrane itself acts as a drainage layer with a water throughput capacity that significantly exceeds the possible influx of water.

Profiled membranes are also used for tunnel waterproofing, where the main purpose of the membrane is not to stop or shut off groundwater, but to ensure its drainage naturally (water flows into the drainage along the walls of the membrane naturally under the influence of gravity). Membranes are also used when carrying out work using the “ wall in the ground", in which membranes allow you to solve quite difficult task protection of the pit from penetration of groundwater.

Manufacturers, types

Today, the market for profiled membranes is represented by several renowned manufacturers. As a rule, there is no fundamental difference in the design of the material. Each manufacturer in the line of materials offered has several brands of membranes, differing in the presence or absence of sealant at the joints, an additional layer of geotextile (woven polypropylene fabric, non-woven polyester coating), single or double lock, perforation, and an additional layer of polyethylene.

TechnoNIKOL company offers comprehensive solutions for protection against moisture residential buildings and commercial properties. Waterproofing systems have been developed using several types of materials. The product line includes everything you need: from primers, insulation boards to protective membranes. Planter – new development manufacturer: universal material with wide scope applications. Planter protective fabric is used as the top layer of a waterproofing system, the primary drainage material, replaces the concrete layer in preparation for pouring the foundation, for constructing areas for laying paving slabs.

Planter membrane is a rolled synthetic protective material. Hollow spikes are pressed into the polymer canvas in a checkerboard pattern.

Automation and control: production facilities

Manufacturing material – high density polyethylene. PVP is produced using extrusion technology. The production process is automated, and adherence to technology is strictly controlled at each stage. To produce particularly durable polyethylene, a special formula of raw materials has been developed. The fabrics are entirely pressed, without seams.

Planter membrane: a universal product

Polyethylene for making planter is a high-strength fabric with a uniform, dense internal structure, which has increased elasticity and resistance to any type of damage.

• Easy to install. Universal material mounted in two directions: horizontal and vertical. The edges of the canvases can be connected using a special fixing tape, without using hot welding technology.

Main functions of protective profile membranes

The Technonikol company produces profiled Planter membranes for use in private and industrial construction. Main functions:

• Protection of external insulation systems from mechanical damage is necessary both at the stage of backfilling pits and during operation.

• Primary water drainage when installing wall drainage. Water drainage is ensured by the cavities of the studded fabric. The minimum moisture removal is up to 5 liters per meter of area.
• Preparation device for a monolithic or slab foundation. The Planter Standard membrane replaces a layer of concrete, which traditional technology poured before installing the slabs.
• As a drainage basis when arranging courtyards and paths, blind area.

Water drainage and wall protection from capillary moisture

• Sanitation of wet surfaces. Installation of canvases on damp walls is allowed: ventilation and free air circulation are provided by channels on the surface of the membrane.
• Protection and removal of moisture from flat and used green roofs. Used in combination with multilayer insulation. Protects the surface from germination of plant roots and deformation of insulating layers.
• Soundproofing. Mounted for soundproofing residential premises: under the floor covering.

TechnoNIKOL membrane protective products for private and commercial construction

There are 2 product types in the Planter line of profiled membranes:

1. Single-layer fabric, marked Standard, Eco or Extra.
2. Two-layer material with geotextile fabric applied over a polyethylene base, marked Geo and Geo Extra.

The TechnoNIKOL company offers Planter Standard for protecting the structures of low-rise private houses. Extra level materials are intended for work at large industrial facilities, in difficult soils, and at significant depths.

Planter Standart: characteristics and application

Planter Standard is a universal membrane designed for use in the construction of private and commercial buildings. The thickness of the canvas is 0.55 mm. The length of the membrane in a roll is 20 m.

Application:

1. In the outer layer of external foundation insulation. The material protects the surface from local pinpoint damage from stones, evenly distributes the load from soil pressure, prevents the penetration of ground moisture, and removes water from the wall.

1. For arranging the preparatory layer for the foundation. In dense soils, the membrane can be installed instead of a concrete pad. At the same time, the issue of reservoir drainage is being resolved. Installing sheets reduces the overall cost of work and saves time: pouring and setting concrete preparation takes up to 2 weeks, and installing polyethylene takes several hours.

1. For laying under the blind area.

1. As insulation for wet basement walls outside and inside the premises.

Eco membrane: the best choice for private homes

Among the profiled products of TechnoNIKOL is the Planter Eco membrane. The canvas is not inferior in functionality to a Standard level product. The physical characteristics and internal structure of the material are optimized for use in private construction. The strength and elasticity of the membrane is sufficient for arranging protective systems in low-rise buildings, inside and outside basements located at shallow depths.

Eco: budget alternative

Also, the Eco Planter profile membrane can be used as a replacement for a concrete pad under the foundation in stable, dry soils, with a depth of up to 1.5 - 3 m, for arranging a base for tiles in private courtyards. The thickness of the material is standard, 0.55 m. The roll contains a solid sheet 20 m long.

Extra products: protection in difficult conditions with increased loads

Extra: material for complex objects

A high-strength membrane, Planter Extra, has been developed for use in industrial construction. Canvases are used:

• When arranging stylobate roofs, multi-storey buildings– regardless of the complexity of the design.

• For the protection of waterproofing materials in industrial facilities under construction.

• When preparing pits for monolithic foundations, during the construction of bridges, roads, tunnels.

• As a soundproofing and additional thermal and moisture-proof layer in underground structures - parking lots, basements of residential buildings.

• When constructing objects in complex, heaving soils.

The strength and elasticity of material marked Extra exceeds that of standard fabrics by almost 2 times. Weight is 0.8 kg per meter.

Geo protective membrane: primary drainage and moisture protection of walls

Planter Geo membrane is a two-layer material. A water-permeable material – geotextile – is attached to a base made of profiled polyethylene. The membrane performs the following functions:

• Drainage.

• Protective.

The canvas, which is attached to the spikes, allows moisture to pass through, but retains soil particles and debris. Channels, which are formed by protrusions on the surface of the polyethylene, drain water to the drainage pipe. Multilayer fabrics are fixed on horizontal and vertical surfaces. The material is used when organizing wall drainage lines, reservoir drainage layer, surface drainage systems on sites where it is planned to lay tiles.

Planter Extra Geo: product for industrial facilities and roofs

Cloth for use in difficult conditions: Extra Geo

Reinforced profiled membrane Planter Geo Extra is a professional material for use:

• In drainage and insulation systems of underground facilities, with a depth of up to 10 m.

• To protect open tunnel structures.

• In the arrangement of green roofs, roofs of business facilities.

• In the construction of open drained sites large area, stadiums, roads.

Extra class material differs from Standard products in increased weight, denser internal structure and improved strength and load resistance.

Characteristics

Auxiliary and connecting materials

In addition to membrane roll materials, the manufacturer’s line includes all the necessary related materials for fixing the canvas to different types of surfaces and connecting strips in the vertical and horizontal plane.

Planter Profile polyethylene profile is made from high-density polymer. The products are designed for pressing the fabric onto waterproofing sheathings. Install the profile on top of the profile membrane, above waterproofing materials. The polymer strip also performs a protective function: the profile prevents moisture from entering the insulating layers.
The following are used as fasteners for rolled profile sheets:

• Dowels with washers. The dowels are made of high-strength steel, the washers are made of dense polyethylene. Used for fixing canvases on all types of vertical surfaces. To reduce the load on 1 fastening unit, a special shape of the pressure washer has been developed, thanks to which the weight of the sheet is distributed evenly over a larger area.

• Flat adhesive fasteners. For fixing expanded polystyrene sheets and membranes to bitumen base use plastic fasteners No. 01 TechnoNIKOL. The adhesive base is firmly fixed to the base, and the polyethylene dowel securely holds the canvas without the formation of “cold bridges”.

Plastic dowel with self-adhesive base

To connect membrane strips to each other, use:

• Planterband is an adhesive tape designed for connecting joints and sealing seams. Polymer-bitumen tape is suitable for working with all types of rolled profiled materials.

• Nicoband roll material for joining sheets with overlapping edges. The base is aluminum, the adhesive is bitumen-based. The adhesive layer is protected by a transparent film.

Aluminum based sealant

Technology for laying protective membranes in TechnoNIKOL insulation systems

The technology for laying profiled Planter membranes is quite simple. To fix the canvases, when using connecting materials recommended by the manufacturer, the use of hot gluing methods and special tools.

Fastening material to vertical surfaces

Installation of membrane protection is carried out both outside buildings and on interior walls wet areas. For installation in private homes, choose a product of the Standard or Eco level. When it is necessary to connect a membrane to a wall drainage line, it is rational to use material with geotextiles.

Planter Standard membrane sheets, when fixed to vertical wall, can be laid horizontally and vertically.

Laying fabric with a geotextile layer

The upper edge of the canvas should be 15–20 cm above the waterproofing installation line. During installation decorative covering Excess material can be trimmed. To fix the sheet, an edge clamping bar is attached.

Aligning edges when mounted vertically

The canvases are laid overlapping. The edges of adjacent strips should be aligned with an overlap of 3 to 4 protrusions. When laying, the seams of the joints are sealed with bitumen-based adhesive tape.

The panels are fixed using dowels or plastic fastenings, if it is necessary to connect the membrane to the bitumen layer.

Horizontal laying of membranes

As preparation for the foundation, Planter Standard is laid directly on the ground. The base must be level, free from hard rocky inclusions. The soil must be compacted. It is allowed to create a gravel cushion up to 10 cm high.

The canvases are rolled out. Be sure to check that folds and creases do not form on the strips. The first roll can be rolled out along the marked line, with the spikes facing down. Next stripes laid with overlapping edges.

Aluminum tape connection

The edges are connected with reinforced tape on an aluminum base.

Connecting strips to textile layer

When using a fabric with a geotextile layer, the edges of the fabrics are connected in two stages. The textile layer is folded back, the polyethylene base is connected with adhesive tape, and the connection is duplicated after laying the edges of the textile.

Inside residential premises, the membrane is laid with the spikes facing up. The membrane performs the function of sound insulation and thermal insulation, protection against moisture infiltration, especially on the first floors. The canvases are laid end to end. The seams between the sheets are taped with polymer-bitumen tape.

Detailed instructions from the manufacturer on the use of Planter Standard profiled membrane.

Usage membrane materials instead of classical concrete preparation when building foundations, it is economically profitable. The costs of arranging the foundation are reduced significantly. In order not to overpay, choose the optimal class of material: for private construction, it is enough to purchase budget Eco canvases. If you need to calculate the number of rolls and choose the type of membrane for a large construction project, contact specialists, because the calculations take into account not only the area and number of floors of the building, but also the characteristics of the soil.

Foundation waterproofing and drainage systems:
profiled Planter membranes.

"Center Building materials" - official dealer and regional representative
most well-known manufacturers of building materials in the central region.

Profiled membranes PLANTER- one of the most modern solutions for buildings and structures with increased requirements for reliability and safety.

PLANTER membranes are manufactured in factories in the European Union in accordance with the highest standards quality ISO 9001 and their characteristics correspond to the best world standards.

Due to the low weight of the profiled membrane, structures are not loaded, and the labor intensity and cost of work are significantly reduced.

The latest technologies embodied in PLANTER profiled membranes and the use of polyethylene as a raw material allow us to confidently assert that the potential service life of the membrane is more than 50 years.

Using the PLANTER profiled membrane as a replacement for concrete preparation in the construction of buildings and structures using the “slab on soil” technology, the average savings per square meter is more than $10.

PLANTER standard.

Profiled membrane PLANTER- This is a high-density polyethylene (HPDE) sheet with molded round protrusions 8 mm high.

The surface of the Planter membrane effectively distributes soil pressure over the entire area of ​​the base or foundation of buildings and structures. Wherein excluded formation of local (point) loads. The space between the wall and the Planter canvas, formed by protrusions, allows allow air to circulate freely, improving the temperature and humidity conditions of the room.

The Planter drainage membrane has a high mechanical strength and resistance to chemically aggressive environments, not susceptible to the destructive effects of mold and bacteria, resistant to the germination of tree roots and ultraviolet radiation. The PLANTER membrane can be laid both horizontally and vertically. If necessary, you can weld the sheets together along a specially provided flat edge.

AREAS OF APPLICATION PLANTER standard

Protection of foundation waterproofing.

The greatest danger to waterproofing is the period of the zero cycle, that is, before backfilling. Because waterproofing is not protected from external influences: mechanical damage, ultraviolet. When backfilling there is a very high risk of damage to the waterproofing membrane construction waste. Yes and when further exploitation buildings there is a danger of chemical exposure to groundwater and tree roots growing through the waterproofing. By building regulations waterproofing protection must be provided. Previously used methods of protecting vertical waterproofing include: Protection flat slate 8mm thick . A brick wall half a brick thick (built additionally for protective purposes). These methods can be characterized as follows: they are very material-intensive and time-consuming to construct.

A modern alternative to them is to protect the waterproofing of walls with profiled drainage PLANTER-standard membranes. Membranes are rolled out projections to the wall waterproofing. This allows the formation of approx. 8mm air gap between soil and waterproofing. All local loads occurring in the soil are evenly distributed over the Planter Standard membrane. According to its technical indicators, the membrane can withstand compression pressures of up to 28t/m2 - this allows it to be used effectively to a depth of approximately ~ 15 meters.

In addition to mechanical protection, the membrane protects waterproofing from UV exposure during long-term construction, from the effects of chemical aggression, and from root germination.

Replacement of concrete preparation.

During the construction of any building, we inevitably encounter such a concept as concrete preparation. It is made of low-grade concrete (B7.5) in order to obtain a flat surface on which subsequent waterproofing work will be carried out. When constructing buildings with low groundwater levels, only anti-capillary horizontal waterproofing slabs In this case, you can avoid the use of concrete preparation by using a profiled Planter membrane. The profiled membrane PLANTER Standart creates optimal conditions for concrete hardening, because The “milk of cement” needed by concrete does not go into the ground. The studded surface of the membrane gives it the necessary rigidity, which makes it possible to lay the reinforcement cage directly to the membrane and immediately concrete. Due to the protrusions, the surface area of ​​PLANTER-standard exceeds the flat surface by 25%. The larger the surface area, the less pressure on the underlying layers of the base. The spiked surface of the membrane creates additional friction in the base, which inhibits the formation of defects and cracks in the base slab.

If you, read all this carefully, then the conclusion suggests itself: using a profiled membrane PLANTER-standard You gain time necessary for laying and strengthening the concrete preparation.

Rehabilitation of damp walls.

Due to the rapid increase in the cost of housing and rented space, previously unused areas began to be intensively developed. underground space. The problem of repair and basement waterproofing buildings began to be discussed very sharply. Restoring waterproofing costs the customer a large amount than high-quality new waterproofing. There are two main methods: restoration of waterproofing from the inside And outside . Check out both diagrams:

Recovery
waterproofing FROM THE OUTSIDE OF THE BUILDING

The difficulty of waterproofing the foundation from the outside lies in the excavation of the foundation and wet walls, onto which bitumen-polymer waterproofing cannot be applied. One of the best solutions to the problem is to use PLANTER-standard membranes outside.
The Planter-Standard membrane must be used on top waterproofing vapor-permeable coating and protrusions to the wall. This not only solves the problem of protecting the foundation from rainwater, but also, thanks to air gap between the membrane protrusions and the wall, allows you to easily remove vapors and condensation. This technology creates an optimal temperature and humidity regime for the wall and prolongs total term operation of the building.

approx. "Center SM": Of course, this method will not allow you to escape from pressure groundwater, but it can remove perched water and sedimentary moisture from the building!

Recovery
waterproofing FROM THE INSIDE OF THE BUILDING

When we restore the waterproofing of walls from the inside, we inevitably face the fact that the wall after repair will be under permanent influence ground moisture. On the one hand, this is good - under the influence of water, the process of hydration of cement and the strengthening of concrete continues. But on the other hand, ground moisture contains many chemically active components that can destroy the wall and cause corrosion of reinforcement. If the wall remains in water without drying out, it will collapse much faster than it will dry out seasonally.

PLANTER-standard can be used to restore waterproofing during the reconstruction of existing buildings in cases where the integrity of the external waterproofing is damaged and water accumulates in the basement. Using Planter-standard membranes; room isolated from wet walls. Restoring a damp wall from the inside involves creating a ventilated drainage gap (8 mm) around the entire perimeter of the basement space. Attaching the Planter-standard membrane projections towards damp wall , we get this gap. We leave gaps at the top and bottom for free air circulation. During periods of heavy rainfall, water that has leaked through the walls will flow down and go down the slope into the drainage pit. It can be located in an adjacent room with a pump that turns on automatically. Next, on top of the Planter membrane, either plaster is attached over a mesh, or plasterboard sheets on the frame - we form a “false wall”. Important and necessary condition:
at internal waterproofing ventilation is required.

Thus, we get inexpensive And fast restoration of waterproofing of damp walls.

PLANTER geo.

Profiled membrane PLANTER-geo- this is a canvas made of high-density polyethylene (HDP) with a spike height of 8 mm, with a layer of thermally bonded geotextile glued to it.

VERTICAL WALL DRAINAGE - filters water and quickly removes it into the drainage pipe. At the same time, according to the conclusion of the Central Research Institute of Industrial Buildings, sand is replaced with backfill soil. Sand will take over the filtering functions PLANTER-geo membrane, whose water throughput is 4.6 l/s per sq.m.
This allows you to quickly and efficiently drain both soil and surface water.

Thermally bonded geotextile used in the PLANTER-geo membrane has a high initial modulus of elasticity - this provides resistance to soil pressure without much deformation, as well as non-silting due to the structure of the fibers. As a result, the drainage system will serve reliably and for a long time.

Application areas of PLANTER geo

Water protection and drainage system
FOUNDATION.

Waterproofing is a system consisting of elements that prevent water from penetrating into a building or structure. One of the main elements of the system is drainage. Drainage helps remove water from the structure, as a result of which it does not put pressure on the waterproofing and does not look for weak points in it. For the long-term functioning of the drainage system, it is necessary to wrap the pipes with geotextiles and backfill them with crushed stone and sand to filter water.

Membrane PLANTER-geo plays the role vertical wall drainage- filters water and quickly removes it into the drainage pipe. In this case, it is possible to replace sand with backfill soil (according to the conclusion of TsNIIPromzdanii). The filtering functions of sand will be taken over by Planter-geo.As the drainage depth increases, the water throughput capacity decreases. The maximum depth depends on the type of soil and can reach up to 12 meters. The membrane is attached to the ground with protrusions and geotextiles. Thermally bonded geotextiles used in the PLANTER-geo membrane have a high initial modulus of elasticity - this provides resistance to soil pressure without much deformation. The second advantage of thermally bonded geotextiles is the ability not to silt due to its small thickness and fiber arrangement.

Water protection and drainage system
exploited ROOF.
The diagram below shows the main design elements:

In 1978, an international standard (ASTM) for serviceable roofs was introduced, which gave rise to the concept of “ inversion roofing» with insulated waterproofing and compulsory the use of drainage layers. The drainage layer allows water to quickly remove from the “roofing cake”, while avoiding pressure on the waterproofing and destruction of the overlying coating from alternate freezing and thawing. Thanks to the introduction of a drainage layer into the roof structure, there is no washout of sand, clogging of water intake funnels, as well as uncontrolled subsidence of gravel due to its undercompaction.

The role of this drainage layer is performed by the profiled membrane PLANTER-geo. PLANTER-geo is laid under sand backfill geotextile up. Water is filtered through thermally bonded geotextiles and removed from the roof to water inlet funnels. The PLANTER-geo drainage composite forms a reservoir drainage layer 8 mm wide and with a water throughput capacity of 4.6 l/s per each sq.m. which significantly exceeds the possible influx of water. Due to the high compressive strength of the profiled PLANTER-geo membrane (reaches 25 t/m2 and the use of thermally bonded geotextiles, the layer drainage gap maintains the stability of its dimensions and does not lose its filtration capacity even under high loads.

In addition, the mass is 1 sq.m. profiled PLANTER-geo membrane is only 650 g, and the filter fabric is already attached to the membrane. Laying processsimplified to one action- rolling out the roll. In this case, the roof structure is not loaded.

Due to a number of advantages, it is recommended to install the PLANTER-geo membrane under all pedestrian areas on existing roofs!

Replacement of concrete preparation using profiled membranes. January 29th, 2014

What do we picture in our minds when we hear the phrase “laying the foundation”? A torn up construction site filled with equipment? Roaring excavators, skidding dump trucks, working bulldozers? No one will argue that a reliable foundation is very important. And if it’s important, it means it’s probably extremely expensive, time consuming and difficult. Let's try to figure out if this is so.

Having considered different types foundations, many today come to the decision to build a house on a monolithic foundation slab. This type of foundation is good because it can be used on almost any soil. It has maximum load-bearing capacity, while being less labor intensive. And another huge advantage is that the foundation simultaneously becomes the floor of the first floor, which significantly reduces the amount of work.

Traditionally, low-quality concrete was poured under the monolith in order to create a flat surface and waterproofing - the so-called “concrete preparation”. Concrete is currently being replaced profiled membrane with projections for mechanical protection of waterproofing, reservoir drainage in underground and above-ground structures.

The profiled membrane ensures reliable separation of the foundation walls and wet soil. Protrusions in the shape of truncated cones form ventilation ducts over the entire surface of the wall, which allows excess moisture to be removed from it.

The use of a profiled membrane to replace concrete preparation gives undoubted advantages:

• . There is no loss of working time for concrete hardening (from 1 to 3 days depending on the thickness of the concrete preparation).


• . There is no need for additional soil excavation and removal.


• . Not required construction equipment and vehicles (excavators, dump trucks, bulldozers).


• . High compressive strength of the membrane


• . Additional protection of the foundation slab from the effects of ground moisture (in the case of gluing membrane overlaps with tapes or adhesives).


• . Reliable protection of the foundation from the germination of tree and plant roots.


• . Protection against loss of cement laitance from the mortar into the soil.


• . It is easier to work in cold and hot weather - there is no need to protect lean concrete from cracking. Replacing concrete preparation with the use of drainage membranes can be done even with negative temperature environment and in rainy weather.


• · The foundation slab can be made immediately after laying out the membrane sheet and laying the reinforcing frame on top of it.

RESULT - Significant reduction in installation cost and time square meter grounds

Profiled membranes are laid after leveling and compacting the soil (crushed stone).

1. Calculate required quantity material, measuring the width and length of the area, and cut the required pieces of material.


2. Lay the membrane with the protrusions down, with overlaps at the transverse and longitudinal seams.


3. The seams must be carefully taped with self-adhesive material.


4. The reinforcement is placed directly on the membrane, which is fixed in a special way. To tie reinforcement you can use plastic clamps. The nodes connecting the reinforcement in monolithic structures do not bear any load; the connections are fixed only in order to give shape at the time of pouring concrete.

Thus, half of the work on laying the foundation has already been completed.
Profiled PLANTER membranes are one of the most modern solutions for buildings and structures with increased requirements for reliability and safety.
