The columnar foundation is common in the construction of wood houses. The weight of such houses is small and the pressure of the design on the ground allows you to reduce the costs of materials for the construction of the base of the house. When arranging a columnar foundation, pits are dug up, the cross -section and depth of which is determined depending on the weight of the material and the features of the design of the walls. Pillars are necessarily at the corners of the load -bearing walls, at the junction and intersections of the internal walls, under the stove. Before construction, it is recommended to choose a good interior here in advance .
Traditionally, concrete, brick or boot are used as a support, a tree filled with concrete asbestos -cement pipes is also suitable. Wooden pillars are necessarily coated with budonon or bitumen, wrapped in roofing material. When using the solution, it is necessary to use the cement of the corresponding brand.
The supports are laid on the ground, the gaps between them remain open for natural ventilation or laid by a brick battle with the subsequent coating of the solution or clay. The upper part of all pillars is aligned along the plane. If the soil is inclined to settling, it is necessary to put pillars 25 cm deeper than the maximum freezing level. It is recommended to sink support pillars in case of heavy weight of the structure, the light structure will not be able to hold the foundation in place, when the columns will be reinforced, they will be pushed upward. For light houses on a columnar foundation, it is necessary to install a shell or anti -pouring shields.
