After press-driving a pile, it can be immediately established what load this can carry on a permanent basis. To check the outer load-bearing capacity of the pile, settlement tests and, in particular cases, proof load testing to DIN EN 1997-1 are also performed.
The inner load-bearing capacity of the pile is guaranteed by means of hydraulic pressure testing at regular intervals on piles taken from a production batch. With pressure testing, random pile samples are tested to failure point. The permitted load is then determined by the inclusion of a safety factor. The result of the pressure test is illustrated as a load /compression curve.
Our construction sites are monitored by an independent health and safety engineering office.
