Foundation piles are used in order to span with piles ground strata, which are not very stable or are unstable. The concrete piles are driven into the foundation material until a sufficiently load-bearing soil or rock stratum is reached. The loads of the supporting structure are then borne either by the friction of the post with the foundation material or the point-bearing pressure of the piles. The piles are used for a wide spectrum of uses from simple industrial building, to vineyards and orchards up to wind turbines.
