In-house load testing and certification on every install..
Compression testing proves the foundation will carry the loads it was designed for. We test in-house on every project and issue an engineer-signed certificate, ready to submit to Building Control and the structural engineer of record.

Compression testing proves the foundation will carry the loads it was designed for. We test in-house on every project and issue an engineer-signed certificate, ready to submit to Building Control and the structural engineer of record.
Why it matters
Most failures in concrete foundations are only discovered after the structure is built. Compression testing every screw at install time removes that risk and gives the structural engineer hard data to sign off against.
What you receive
A full compression test report covering each tested pile, including torque values, displacement at load, photographs and a signed declaration of conformity.
- Per-pile torque and displacement data
- Photographic record of each test
- Declaration of conformity
- Issued within 48 hours of install
