What should be the depth of the foundation for the two-storey house of foam blocks - expert advice

Structures of aerated concrete is relatively easy and does not create a significant load on the ground, such as brick or w / w of the building.For buildings in 2 floors are used different types of foundations.But more often than individual developers equip the tape, which is preferred for various reasons.

consider all its advantages, as well as the installation of the technology will not be - a topic for another article on the tape foundations.But with the depth necessary to understand separately, since it is on this issue, with the similarity in all the others, there are many different interpretations.

What does this option depends?If we analyze all the available access recommendation and testimonials from those who have already built, we can distinguish two main points.

freezing depth

It is defined as the climatic conditions in the area and the characteristics of the soil.Primarily, the composition of the soil and groundwater aquifers located.For this reason, a clear answer on how deep bury the tape, without the site inspection will not give any one person.

For our country can meet these recommendations - from 0.7 to 1.5 m .But in general it.A particular depth bookmark ribbon is determined individually for each building.On the sands or marshland it can be much less - up to half a meter.And here, for example, on loam or clay areas on the contrary - increased to 1.8 - 2 m .

need for basement

Actually, it is not a burial as such, but the height of the foundation, that is, the structure of the basement.But this is at the discretion of the owner.For more information on the basement we talked.

possible to meet opinion that in the depth of the foundation affects the quality of the scheme and its reinforcement.With this quite difficult to accept, since the shifting of the ground it's like to push on the surface - clean artificial stone or reinforced metal frame.

And here are some other options to consider as follows:

• of what made the overlap?
• size foam blocks;
• roof construction and roofing materials and "pie".

What advise individual developers

First, study the experience of neighbors who have built any buildings on adjacent plots.Even if these structures and of foam, then some useful information (soil, groundwater) can be obtained.

Second, invite a professional for geological research area.The feasibility of such a solution is obvious.The specialist will complete "layout" and the relevant recommendations, and in writing (in the form of opinions).Now let's compare.For this service will have to pay about 1 250 rubles / ha (depending on the complexity of the work and a number of other factors, but not more than 4000 private home).

And if the foundation is "lead", any misalignment of the walls, there will be cracks?How much will result repair buildings already in operation?

Based on the foregoing, guided by the advice of various "experts" should not be.In which case, to pay for all the omissions do not have them, and the host.
