UK testing contractor Testconsult has launched it latest pile integrity assessment system. The system comprises two main elements, the TDR-2 data acquisition unit and processing and reporting software T-PA.

Testconsult managing director Dick Stain says the TDR (transient dynamic response) method has long been regarded as the best technique for foundation evaluation.The system measures the input force as well as the resulting pile response.This allows the shaft length and cross section to be examined.Data can also be viewed in both frequency and time domain.

Originally designed solely for in-house use, the portable and user-friendly equipment was such a hit with the firm's engineers it was decided to release it commercially worldwide.The TDR is waterproof, has a modem facility and can store up to 700 test results.

The launch coincides with the recent release of the CIRIA report 144, Integrity testing in piling practice.
