Prepare the site — the upper layer of soil is removed from the site. Make markings. For this, pegs are driven and the corners of the future base under the house are noted, but at the same time it is necessary to retreat from the edge by 0.5 m. On the external and internal border of the foundation, as well as along the base axis, the twine is pulled. The location of the piles is marked, between which there should be 1.2 — 1.5 m. This work needs to start with the corners.
