Integrity test in Hanover
Low-strain and cross-hole, large quantities. For Hanover and southern Lower Saxony, with own measurement technology and travel distance about 2.5 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.
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.
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.
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.
