Principle
The test is based on wave propagation theory. The name “low strain pile integrity test” stems from the fact that when a light impact is applied to a pile it produces a low strain. The impact generates a stress wave that travels down the pile. When the downward stress wave encounters a change in cross section or in concrete quality, it generates reflected wave that is later observed at the pile top. By analyzing the propagation time,amplitude and phase of that reflected wave, it has the evaluation of pile integrity ultimately.
