Building a house is always accompanied by a lot of questions, especially if this house is being built for yourself, with love, because you really want it to turn out warm, cozy, reliable... the best. But making it this way, it turns out, is difficult, since a lot of nuances have to be constantly kept in mind and analyzed, even at the very early stages. All you have to do is decide on one of the very first questions of any individual construction: which house is better to build for permanent residence? – the answer to which not even every professional can give. But we will still try to do this with the help of this article.

In order to be able to answer main question article, you need to decide what the choice will be made from. As you know, houses can be small, medium and large, as well as brick, wood, frame, etc., that is, different in size and material of manufacture.

Let's start with size. It should first of all be determined by the area of ​​your plot, as well as your financial viability, because building a house that you simply cannot “heat” later is a very stupid idea, so sensibly assess your capabilities and move on to choosing the material.

Houses for permanent residence can be built from lightweight materials ( wooden beam, SIP panels, insulated wooden and metal frame) or heavy (ceramic, foam and gas blocks, bricks), the use of each of them must be strictly justified by the requirements that you place on your future home. Read on and understand what requirements we are talking about.

Durability.

One of the main requirements for any home intended for permanent residence is durability. Its leaders are brick houses, as well as those built from aerated blocks, their lifespan exceeds 75 years, they live a little less wooden houses- about 50 years, and frame ones - on average 25-50 years, it all depends on what material the frame will be made of, what will be used as insulation, how well the ventilation will be thought out in such a house, etc.

Construction speed.

Everything that requires “wet” work (using mortar) is built much slower than houses made of lightweight materials: if the latter can actually be built in a couple of months, or even a few weeks, then building a house from brick or block will take about at least a year and a half (and then if we're talking about about a small building - up to 150 sq. m. by area - and finishing work is not taken into account).

Price.

A heavy house is always more expensive to build (2 times, and sometimes 4 times) than a light one, so in conditions of very limited financial resources, preference should be given to the second option - so at least there will be something left for a decent finish.

For orientation, here is approximate cost construction of houses from various materials.

A frame house with not too thick walls will cost you per square meter. at 35$. The same house, but built with SIP panels - $30. Let's add to these figures the costs of transportation and construction of a lightweight foundation, and we get the total cost of one sq. m. up to $240.

In a heavy house, prices will be higher: 1 sq. m. aerated concrete wall– $55, brick (1.5 bricks thick, 38 cm) – $65, ceramic – $70. Again, we add the foundation, transportation, and don’t forget to add about 40 percent to pay for the work of the builders. Total sq.m. in such houses the cost can reach $600.

Possibility of partial financing.

Money can be invested in construction at a time, or it can be done in stages, but if the first option is possible in any construction, then partial financing is acceptable only for the construction of heavy houses: they built as much as there was enough money for, suspended construction for a while until the necessary ones were collected again savings, resumed... In frame construction this option is excluded, materials need to be purchased immediately and in full, so if you don’t have the required amount, either wait until you have it, or start building a house from blocks or bricks.

Fire safety.

Based on fire standards for each type building materials assigned its own fire resistance class, the higher it is, the less materials able to withstand fire:

Fire resistance class II is assigned to houses made of foam, gas blocks and bricks;

III class – wooden buildings;

IV class - light houses with a wooden frame.

Moreover, light houses are not just a fire hazard, they are often toxic when burning, so all those who care about their health and prefer to be prepared for emergencies in advance should avoid building such houses for permanent residence.

Thermal inertia.

Thermal inertness is the ability of a material to accumulate and release heat. Heavy materials(brick and building blocks) have this characteristic, but light ones do not: they heat up quickly and cool down just as quickly, so according to this criterion frame houses suitable and comfortable for permanent residence only in those areas where there are no harsh winters.

Comfortable and environmentally friendly.

In terms of comfort, any of the above house options will be good (they will have the required humidity and temperature), the main thing is to follow the construction technology and be very responsible about ventilation, vapor barrier and interior finishing materials.

Which house is better to build for permanent residence: conclusions.

Of all of the above, and taking into account our climate, we definitely recommend refusing frame construction and give preference to heavy or wooden house. For those who still have doubts, we will briefly outline the main pros and cons of each of the house options.

Brick houses.

  • strong and durable;
  • service life more than 100 years;
  • environmentally friendly;
  • fire resistant;
  • allow you to build on or add something at any time;
  • do not rot or shrink.

Frame houses.

  • have high speed construction;
  • cheap;
  • do not shrink;
  • earthquake resistant.
  • have poor internal sound insulation and tightness.

Houses from PGS.

  • environmentally friendly;
  • easy to erect;
  • relatively cheap;
  • fireproof;
  • have excellent sound and heat insulation;
  • characterized by a favorable internal microclimate.
  • subject to shrinkage;
  • require a solid foundation.

Wooden houses (made of timber).

  • reliable;
  • environmentally friendly;
  • do not require finishing;
  • can be built independently;
  • have best properties thermal conductivity;
  • do not require a strong foundation;
  • can be erected at any time of the year;
  • short-lived;
  • unable to withstand fire.

Video.

To begin with, a small educational program. PGS is a sand and gravel mixture. It doesn’t take a rocket scientist to guess that its main components are sand and gravel. This mixture is extracted from the sea and river bottom. Its quality and binding properties largely depend on the place where the mixture was taken.

ASG is the basis of structures

ASG is the main component of many concrete and reinforced concrete structures(house foundations, road surfaces and so on.).

ASG is divided into several types depending on the sand/gravel ratio, the size of the gravel grains and other indicators: strength, frost resistance, the presence of silt and clay particles, etc.

OPGS is an enriched sand and gravel mixture. It differs from PGS by an artificially increased amount of gravel. In OPGS, the share of gravel is approximately 25-75%, while in ASG it is 10-20%.

The main components of concrete from these mixtures are cement, PGS or OPGS and water. But to receive quality concrete certain proportions must be observed.

Preparation of concrete from OPGS

The same applies to concrete from ASG: the proportions of the constituent materials will depend on what brand of concrete you need to get at the output, what brand of cement you take, and what is the ratio of sand and gravel in your ASG.

It is usually indicated at the time of purchase, but if you do not have this information, then there are many ways to approximately determine this ratio yourself, at home. For example, sift part of the mixture through a metal mesh.

Sand and proportions

As a rule, there is no need to add sand to such concrete; there is already enough of it in the ASG itself. When using some types of ASG, on the contrary, crushed stone is added.

If you need to prepare concrete for the foundation, then it is best to take a ratio of 1:8, that is, for 1 part cement 8 parts ASG. This ratio is verified and the most optimal, although it is also recommended to know. And the video in this article will show in practice how you can use PGS.

It is almost impossible to build a stable and durable base without the use of concrete, since this material serves as the basis for any structure. The durability and reliability of the finished building depends on the quality of concrete, so you should take a responsible approach to the production of the solution. Very often for construction on private suburban areas developers are preparing concrete from PGS ( sand and gravel mixture) with your own hands. Before choosing this option, it is worth learning about all the intricacies of its manufacture.

Selection of materials

Having decided to develop the site, you should purchase all the building materials that may be needed for the work. You need to purchase sand-crushed stone mixture exclusively from time-tested manufacturers.

It is worth knowing that when making concrete from PGS, the proportions of gravel and sand in the mixture may differ. For example, the classic PGS (unenriched) contains only 20 percent gravel, while the enriched one contains 75 percent of the material.

Typically, experts advise using an enriched composition, in which crushed stone predominates. Components for the production of PGS, which are mined from the bottom of a river or sea, have high quality characteristics, so it is recommended to add them to prepare the mixture. River and sea components (gravel and sand) contain virtually no impurities, which increases the adhesion of the mixture to other elements of concrete. As a result, the master is guaranteed to receive high-quality PGS concrete for the foundation, the proportions of which will fully comply with the standards.

Subtleties of preparing the solution


Make it yourself concrete mortar for a base using gravel and sand it’s quite simple. For this purpose, certain tools and necessary raw materials are pre-prepared:

  • Shovel;
  • Dry cement;
  • Pure water;
  • Sand and gravel;
  • Standard size bucket;
  • A concrete mixer or trough in which the components will be mixed.

In order for the solution to be of high quality, it is necessary to adhere to a certain ratio when preparing it. If an enriched composition is used for work, then the ideal proportions of PGS and cement for concrete are 8 to 1, respectively.

Next, of course, water is added, the volume of which is determined practically based on the state of the gas mixture. Often the composition is moistened, and therefore when using the mixture you will need several times less liquid than when using a dry composition of gravel and sand. Be that as it may, the water is not poured in immediately, but gradually, otherwise there is a risk of getting a solution that is too liquid. The ideal density of concrete is similar to the thickness of sour cream. Having achieved this consistency, you should stop adding liquid.

If you plan to use a classic mixture, then you need to approach its selection with particular care. Maximum size gravel grains should be 8 cm, but if the fraction of the material exceeds this figure, then such a pg is not suitable for concrete. Regarding the proportion for an unenriched mixture:

  • Sand and gravel - 6 parts;
  • Cement – ​​1 part.

As for cement, professionals advise paying attention to Portland cement, which has excellent astringent characteristics. It is best to purchase material M300, M500 or M600. Cement grade 400 has a certain disadvantage - instant setting, so it should not be used. Not everyone knows that the rapid hardening of cement when pouring the base is fraught with the formation of cold joints, which deteriorate the quality of the finished base.

What else is worth remembering when making concrete from PGS? The proportions in buckets are slightly different. One vessel holds:

  • Cement – ​​15.6 kg;
  • Mixture of sand and crushed stone - 18 kg.

IN in this case the proportion of elements for the classic mixture is 2 to 14, respectively. For an enriched composition, 1 part of cement to 9 parts of pgs is used. Don't forget about water. By strictly following these ratios, you can obtain concrete of the highest quality.


Many craftsmen wonder how much pgs is needed per cubic meter of concrete. To calculate the volume of the mixture, you should focus on the mass of all elements. In addition, the brand of cement used also plays an important role. For example, for the production of M300 concrete the following is used:

  • Cement grade 400 – 0.382 t;
  • Gravel – 1.08 t;
  • Sand – 0.705 t;
  • Water – 220 l.

For M100 concrete the following is used:

  • Cement grade 400 – 0.214 t;
  • Gravel – 1.08 t;
  • Sand – 0.87 t;
  • Water – 210 l.

Almost always, manufacturers of sand and gravel compositions indicate on the bags the consumption of sand and gravel per 1 m3 of concrete.

Sometimes a different payment system is used. For example, to build a basic structure you need concrete mixture M300. To make 1 cubic meter of solution you will need:

  • Cement – ​​0.38 t;
  • Gravel – 0.8 m3;
  • Sand – 0.5 m3.

If these calculation methods seem too complicated, you can follow the simplest path that professionals use - turn to a special table. It is enough to find the name of the material itself (“concrete from PGS”) and the proportions. The table will tell you the appropriate quantities of all components to create a high-quality solution.

A little more about concrete:

I contacted GefestStroy in June and decided to build a house. I came to the guys' office with blank slate paper, and in September we already got a house like this! I am very glad! Thank you!

Good afternoon. I am very pleased with the work of the guys, they did everything quickly, efficiently, at an affordable price. I RECOMMEND!

Last year, I contacted this company and ordered a bored foundation on piles from them. I was pleasantly surprised by the quality and quick turnaround time of the work. This year I ordered the construction of a house from them. We agreed on the material, signed a construction contract and started work. I would like to express my gratitude to the managers for their responsible approach to work. I share with you the result of their work.

After analyzing many proposals, it was decided to build a grillage foundation on bored piles by GefestStroy. The idea seemed dubious due to the relatively low cost of the proposed work. My fears were in vain))) I was pleased with the result. I would like to note a responsible approach to my work and good faith compliance technologies. All work is carried out strictly in compliance with all agreements and deadlines specified in the contract. Guarantee stipulated. In my case the main part Money I paid for the construction of the zero cycle only upon completion of the work. I was surprised by the fact that the site was leveled using a level before construction.

Hello! My husband and I bought a plot of land; this year we had enough money, only for the zero cycle. We ordered a bored foundation from the guys and really liked the quality of the work, the production time and the price. They completed all the work in 2 days. THANK YOU SO MUCH!
