Dynamic load test in Hanover
Drop weight up to 12 t, evaluation per CAPWAP. For Hanover and southern Lower Saxony, with own measurement technology and travel distance about 2.5 hours from Gotha.
What the test delivers.
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.
Details on the method are on the service page Dynamic load test.
Boulder clay and meltwater sands of the Saale glaciation, underlain by mesozoic marl and clay, locally salt domes with leaching phenomena. Sand and marl alternate over short distances.
A pile in boulder clay carries differently from one in the sand next to it, even though both are the same length. Without testing the difference only becomes visible once the structure settles unevenly.
Dynamic load test in four steps.
- Expose pile heads, apply transducers
- Series of blows with drop weight, measure force and velocity
- CAPWAP model analysis, separation of shaft and base
- Report with bearing capacity and assessment per EA-Pfähle
The structural engineer gets numbers instead of assumptions. Measured bearing capacity allows a proof per Eurocode 7 without blanket safety margins.
Hanover and southern Lower Saxony is geologically inconsistent. The test shows what the pile carries at exactly this spot, not what the ground model would suggest.
Differential settlement causes cracks, tilting and re-foundation. Tested piles are the cheapest part of structural stability.
