These are elements of precast reinforced concrete used as foundations in sedimentary grounds. The driving of the piles is done by means of a diesel hammer. One of the great advantages of precast piles is that the quality of the concrete can be guaranteed due to the fact that is done in our plant under the strictest quality controls. Carrying out the process also happens to be faster, the real length of the drill for each pile, and the real capacity of the underground is obtained during the driving when these are rejected.
