The depth of the foundation laying

If you decide to build a building with a basement, then the question of the depth of the foundation laying for you is very relevant. Most often they make such floors only on the floor of the house. Experienced builders say that the foundation should be laid no less than the level than the earth freezes. If this depth is correctly calculated, then your foundation will be more reliable and protected. But do not forget that the depth of the foundation depends on several points:

Dear friends of our site, as you know, now a metal chain is used very often in the repair and construction of many firms, you can find out more about it by passing the link we said.

Type of soil for construction

Depth to groundwater

The depth of freezing

The type of soil has a strong influence, how it changes its volume when freezing in a wet state. Depending on this, the types of soil are distinguished:

Slightless

Not abutiable

Bender

Which soils are better under the foundation.

The best soil is layered and rocky continuous soil, dense clay and sandy coarse -grained soil.

On plant soil, peat, alloy and bulk soils are categorically not advised to build.

At the time of design, do not forget about the level of groundwater. If the level is high, this will lead to additional waterproofing costs. In this case, it is cheaper to abandon the ground. The freezing depth depends on climatic conditions. On a rocky and half -sustained area, the depth of the foundation does not depend on groundwater and freezing depth. If the soil is gravel, then the depth will be 0.5 m. not given the depth of freezing and groundwater.
