Selection of the foundation

Selection of the foundation is an important stage of construction. These recommendations are valid provided that dense clays, loam, sandy loam are deposited from above. When “weak” soils need an individual approach, it all depends on the geological conditions. The length of the piles will be longer, depending on the thickness of the soil layers. For good dense soils.

Frame (tree, LSTK):
1 floor: F76х2000х3.75; F88,9х2000х3.75 – the minimum distance from the ground.
F76х2000х3.75 – if the socle from the ground is 50-40 cm.
2 floors: F76x2500x3.75; F76x3000x3.75 – the minimum distance from the earth
F76х3500х3.75 – if the socle from the ground is 50-40 cm, or there is a slope.

Bar (150×150, glued):
1 floor: F88,9х2500х3.75 – the minimum distance from the ground;
F88,9х3000х3.75 – the socle 50-40 cm;
F114x2500x3.75
2 floors: F88,9х3000х3.75 – the minimum distance from the ground;
F88,9х3500х3.75 – if the socle from the ground is 50-40 cm, or is
slope;
F114x3000x3.75

Bar (more than 150):
1 floor: F114x2500x3.75 – the minimum distance from the ground;
F114x3000x3.75 – the plinth of 50-40 cm.
2 floors: F114х3000х3.75 – the minimum distance from the ground;
F114х3500х3.75 – if the socle from the ground is 50-40 cm, or there is a slope.

You also need to take into account the slope of the site, and take into account, based on this, the length of the pile. For example: a one-storey wooden “carcass”
Piles need to be twisted to a minimum distance from the ground, but there is a slope of 0.5 m,
on the one hand choose F76x2000x3.75, on the other: F76x2500x3.75
Step piles 2m.
