Integrity test in Hamburg
Low-strain and cross-hole, large quantities. For Hamburg and the northern German coastal region, with own measurement technology and travel distance about 4 hours from Gotha.
What the test delivers.
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.
Details on the method are on the service page Integrity test.
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.
Integrity test in four steps.
- Clean pile heads, define measuring points
- Low-strain per pile, cross-hole between measuring tubes if needed
- Signal evaluation, flag conspicuous piles
- Report per pile, documented and legally sound
The structural engineer gets numbers instead of assumptions. Measured bearing capacity allows a proof per Eurocode 7 without blanket safety margins.
Hamburg and the northern German coastal region 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.
