Integrity test in Cologne
Low-strain and cross-hole, large quantities. For Cologne, Bonn and the Rhineland, with own measurement technology and travel distance about 3.5 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.
Rhenish terrace gravel over tertiary sands and clays, in the surrounding area loess and lignite open-pit mining with dumps and large-scale groundwater lowering. Rising groundwater changes the stresses in the ground over decades.
On dumps and in lowering cones, experience values are worthless because the ground no longer has a naturally grown profile. Settlement occurs there with delay, often years after acceptance.
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.
Cologne, Bonn and the Rhineland 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.
