Columnar foundation
A columnar foundation is an ideal and simple option for constructing lightweight buildings. On such a foundation, you can make a building from foam blocks, but before starting construction, you need to examine the soil composition: if it is uniform and compacted, then it is possible to make a foundation from brick or foam blocks.

It is important to remember that building a foundation with your own hands is a job that requires patience. It is best to make a columnar foundation by pouring it or using brick or concrete blocks, simply installing them in the corners and in places of corner elements of the walls.


The work begins with marking the proposed structure. Then the turf mom data is removed to a depth of about half a centimeter;
Dig holes in the locations of the posts. The depth of each hole is at least 15 cm from the level of soil freezing;
The bottom of each hole is filled with sand and gravel. The resulting embankment must be compacted;
In case of installation of poured columns — make wooden formwork with reinforcement. There are two ways of reinforcement. In the first one, ready-made reinforcement grids are simply laid, and in the second one, rods are laid out at intervals of 200 x 200 mm and fastened with wire at the intersection. For installation of brick columns, this material is laid out with a thickness of one and a half bricks with obligatory seam dressing for the strength of the structure. If you plan to build a powerful barn, then you can use concrete blocks for the columns. It is also possible to use small foam blocks for the columns;
Make concrete mix and pour. One cubic meter of concrete mix is ​​enough for approximately 10 m2 of pillars.
To make concrete mortar it is important to keep the correct proportions. For this purpose you will need:
crushed stone or gravel - 6 parts;
sand - 3 parts;
cement - 1 part;
water - 1 part.
