What is the best foundation for a house made of aerated concrete: reinforced concrete, tape or columnar
Many builders are thinking about the best foundation for a house made of aerated concrete to choose. There may be several options. Each of them will be considered separately below.
Difficulties in choosing a base for construction of aerated concrete
In principle, on tape, reinforced concrete orA pile foundation can be erected a house whose walls are made of aerated concrete. But some foundations can lead to the need for premature repairs. With regard to cellular concrete, many private developers are rushing between the varieties of foundations. After all, the material is easy enough, which leads to the temptation to save and build the building on an unclouded foundation. But this is the most common mistake. After all, if you build a shallow foundation for a house made of aerated concrete, this can lead to the formation of cracks on the walls. Their cause is a violation of the balance between the main forces of the system, including soil, foundation and house.
Features of a quality foundation for a house
In order to obtain a good base,It is necessary to ensure an even distribution of the load from the building weight to the soil without the effect of precipitation. If the system that includes the base and construction is unnecessarily light, then it will not be able to cope with the forces of frost heaving of the soil. This will lead to deformation phenomena in the wall area.
Selecting the tape base
Thinking over the question of what is the best foundationfor a house of aerated concrete to choose, you can prefer a tape system. It will not be the worst option. If the structure is placed on the freezing line, the ejection forces will act solely on the side parts of the system. This option will be more acceptable for a house from a gas block, in which more than one floor. This will balance the forces.
When deciding the question of what kind of foundation is neededfor a house made of aerated concrete, having one floor, it is preferable to abandon the tape. A small building or a bath will not last long on such a system. It will not provide durability to the building, which will eventually crack the walls, and the foundation will be gradually pushed out, unevenly. But if you firmly decided to resort to the creation of a tape, then it is necessary to make a calculation for a specific case. This, perhaps, will avoid negative consequences. Experts recommend in this case to use a shallow system, installed on a sand cushion.
Peculiarities of construction of a ribbon shallow base
Before building a foundation for a house fromaerated concrete, which is better - it is recommended to learn from the professionals of their business. They most likely will not advise the tape. But if you have firmly decided that it will form the basis of the building, then it is necessary to apply large-fraction sand for backfilling, which must be carefully compacted. It will act as a replacement for the soil soils on the non-sooty soil. However, the pressure on the surface of the tape from below will be eliminated. The lateral surfaces of such a system do not have large dimensions, but the weight of the walls will be optimal to ensure a balance of forces.
Originally it is necessary to mark out the territory,clear it and remove the top fertile layer. Then dig a trench, which you need to arrange around the perimeter of the future house. Sand is poured onto the bottom and it is rammed, followed by a layer of rubble. At the next stage, the formwork is installed, the reinforcement is laid on the brick supports, and concrete is poured. Once the solution has strength, we can assume that the base is ready.
Choice of columnar base
Reflecting on what is the best foundation for homefrom aerated concrete to choose, many prefer to resort to the construction of the columnar foundation. This option is also acceptable, but the system must necessarily have a reinforced concrete grillage. On the presence of a basement in the building is not worth thinking about - in this case it can not be built. It attracts developers a low cost of work and materials, as well as the simplicity of the process. However, it is necessary to carry out calculations that are not less easy than, in the case of a tape base, which will allow to determine the number, diameter and length of poles.
The technology of columnar foundation
If you were thinking about the question of which is betterthe foundation for the house of aerated concrete to choose, and decided to stop on the support base, then start work also costs with marking and excavation. The latter suggest the preparation of pits, which are necessary for the installation of poles. Once the supports are mounted, you can pour them at the base of the concrete, check the correctness of the location in relation to the vertical and leave it for the drying period of the solution. Then you can start making formwork to create a grillage. It is a reliable reinforced concrete belt that matches all the existing supports into one system.
Choosing a reinforced concrete base
Before you build a foundation for a house fromaerated concrete, which is the best of all existing - it is worth asking specialists. They recommend using a monolithic slab. It is able to extinguish the seasonal changes in the soil perfectly, ensuring a uniform and minimal pressure on the soil, compared with all other bases. This solution wins on all parameters, in particular, on the price, ease of creation, as well as on compliance with the requirements imposed on foundations for light buildings. The reinforced slab can be poured under the area of the house or at all to get a concrete monolith of factory manufacture.
If you have not decided which foundation to choosefor a house made of aerated concrete, it is better to choose a reinforced concrete. This is due to the fact that any movement of the soil will not contribute to the occurrence of cracks, the plate will rise with the house and fall into its place.
Calculation of piling foundation
The parameters of the piles will depend on many factors,including the bearing capacity of the soil, wind and snow loads, as well as the mass of the future construction. The recommendations below will help you calculate.
If you decide to choose a supporting foundation for your homefrom aerated concrete, the example of calculation will assume knowledge of the mass of all elements of the construction structure. It is important to take into account all kinds of the above loads, including household. At the next stage, you can add all the data obtained, which will determine the effective weight load from the house. Now it is proposed to calculate the area of the building. It is necessary to determine the pitch between the piles, where the minimum distance between the supports will be needed. Carrying capacity of soil in 2,5 kg / m2 will allow to calculate the area of heels of supports. According to it and the received weight, you can find the permissible number of piles. By the way, the minimum distance between piles on ordinary soils is 1.7 m. Between each two piles, a step of 0.5 m or more should be provided, otherwise the base will lead.
If you want to get a quality construction that will last for a long time, then it is worth choosing a columnar base.
