Today's high foundation loads and fast track jobs require modern construction control. The Pile Driving Analyzer® (PDA), Pile Integrity Tester™ (PIT), Cross-Hole Analyzer® (CHAMP) and the signal matching analysis CAPWAP® programme serves to verify the integrity, driving stresses, hammer performance and bearing capacity as well as quality and consistency of various pile installations. We also provide vibration and sound monitoring services using the SSU Seismograph during pile installation. This could protect both owners and contractors from potential litigation should adjacent properties be damaged during the course of construction.
