When laying the foundation, a very important factor is the correct determination of its depth. According to this criterion, all foundations can be divided into two main groups: profile (buried) and low -great -beam (shallow).
When laying the unimportant foundation of the structure, it is necessary to install at a depth of about half a meter, and when laying the foundation of the profile type of structure, the soil should not be installed above the level of freezing.
Well, if you consider that in almost all areas of the country, the soil can even freeze by one and a half meters, then it is not at all difficult to understand that such specialized foundations are very different from the foundations of the unpromised type in terms of costs for all materials used, which means that in terms of total cost.
It is advisable to use profile foundations for wood houses that are planned to be covered with brick and for the initially heavy brick buildings. But it should immediately take into account that the price of such a foundation may be even comparable to the price of the house itself.
In general, there is a stereotype that it is necessary to install the most powerful foundation under absolutely any house, then absolutely no spring moves will be terrible for it. But still, according to experts, the ratio of reliability and the cost of the foundation should be within reasonable limits.
The foundations of a low -grained type are acceptable exclusively for light buildings. If there is a high level of groundwater on the ground, and they fall into the soil freezing layers, it will be better to choose a more reliable type of foundation, or carry out special work that is guaranteed to ensure a significant decrease in groundwater level.
