Integrity test in Düsseldorf
Low-strain and cross-hole, large quantities. For Düsseldorf and the Ruhr area, 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.
Lower Rhine terraces of gravel and sand over tertiary, in the Ruhr area carboniferous with historic mining, mine water management and subsidence areas. Filled areas from the industrial era are widespread.
Over old mining and in fill areas the ground is not what the map shows. Cavities, foundation remnants and varying compaction make any statistical approach unusable.
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.
Düsseldorf and the Ruhr area 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.
