Full Displacement Pile (FDP) |
 |
The FDP-system has a key advantage over the CFA-method in that it transports virtually no drilling spoil to the surface. It is suitable in displaceable soils. The drill rod has an auger as starter, followed by the displacement body and an extension casing. During drilling and extraction, the surrounding soil is displaced. Concreting and reinforcement is executed as in the case of the CFA-pile. |
