Integrity test in Frankfurt am Main
Low-strain and cross-hole, large quantities. For Rhine-Main region, with own measurement technology and travel distance about 2 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.
Frankfurt clay, a tertiary, overconsolidated clay with embedded limestone bands, underlain by Frankfurt limestone. The clay creeps under sustained load, its stiffness depends on stress level and time. Combined pile-raft foundations are standard here, especially in high-rise construction.
Creep deformation does not show up in a short-term test or in a calculation with experience values. Whoever sets the load split between raft and pile without measurement has an assumption, not a proof.
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.
Rhine-Main 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.
