Load testing and integrity testing for Hamburg and the northern German coastal region. Own measurement technology, test force up to 40,000 kN, travel distance about 4 hours from Gotha.
Elbe marsh with clay, peat and silt over load-bearing sands. The soft layers reach more than 20 metres deep in places, plus tide-affected groundwater. Bearing capacity only develops at depth, shaft friction above it is low and time dependent.
Whoever applies shaft friction in the clay calculates a bearing capacity that does not remain after consolidation. Negative shaft friction from settlement of the soft layers loads the pile further instead of carrying it.
Untested foundations are not a cost risk, they are a structural stability risk. Differential settlement, cracking and re-foundation cost many times the price of testing.
Typical construction tasks: Port and quay structures, logistics halls on soft layers, housing in the marsh, bridge structures.
In Hamburg and the northern German coastal region the ground often leads to static load test. We make the final choice based on the ground report and pile concept, not on instinct.
Bearing capacity of several piles within one day, evaluated per CAPWAP. The method per DIN EN ISO 22477-4 delivers shaft friction and base resistance separately and fits where the construction schedule does not allow a week of setup.
Drop weight up to 12 t, evaluation per CAPWAP
The direct proof per DIN EN ISO 22477-1. The load-settlement line shows the real load behaviour under sustained load, up to 40,000 kN test force. Basis for foundation optimisation and for any disputed proof.
Up to 40,000 kN, own loading platform and beam system
Test of construction quality: length, cross-section, necking, defects. Low-strain from the pile head for the whole site, cross-hole between measuring tubes for the core of large bored piles.
Low-strain and cross-hole, large quantities
All questions on process, methods, standards and scheduling are in the FAQ section.
A soil survey and pile concept are enough for a reliable answer. Travel distance about 4 hours from Gotha.
