The foundation is the basic part, the durability of the whole house will depend on the strength of which. If a house is planned without a basement, the foundation is laid to a depth of 1.2-1.5 m. The deeper the foundation is laid, the less it is subject to external damage.
Foundations are of various types. The most common type is strip. It is a continuous tape on which the load load is evenly distributed. The lower part of the strip foundation is the widest part – a pillow, the height of which is from 30 to 40 cm, and the width is from 40 to 80. On these pillows, foundation walls are built about 25-50 cm high. But this foundation is not suitable if the level of ground WHO is too high.

The second type of foundation is a pile, which is the best suited for a light wooden house or gazebo. It is a grillage of wooden beams that rest on concrete piles of a small height, previously mounted in the ground. Typically, piles below in the ground are concreted, at the top – fixed in the formwork.
The third type is a columnar foundation that can be used for a brick, but still not too high and heavy house. The piles in this design are replaced by concrete blocks on which reinforced concrete grillage is installed. Work with such a foundation does not take much time, since it does not require a large number of land work. Therefore, columnar foundations are one of the most economical.
The principle of slab foundations is built on the construction of a reinforced concrete slab, most of which remains on the surface. The plate is able to evenly distribute the weight of the building over the entire area, and the pressure on the soil is significantly reduced. Such a foundation can easily protect the building from destruction.
