![]() ![]() The test is based on wave propagation theory. The TDR test requires minimal of preparation and is able to find defects corresponding to cracks, reductions in section and zones of poor quality concrete The test measures: Pile length, or depth to anomaliesPile head stiffnessPile shaft mobility – which is dependent on pile section and concrete propertiesThe software also produces computer simulations and impedance profiles of the test result, to analyse in detail any intermediate pile shaft responses. Pile integrity testing using low strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations. It is cost effective and not very time consuming.
