Pile Integrity Tester




PIT performs low strain integrity testing also called Sonic Echo Testing. It detects potentially dangerous defects such as mojor cracks, necking, soil intrusions and in some situations can determine unknown length of piles or shaft.

The PIT test consist of attaching an accelerometer to the top of pile to be tested. The accelerometer acquires data resulting from impact of a small hand-held hammer. If a defect is present along the shaft, its size and location can be estimated by analyzing the propagation and reflection of the wave induced on the pile by the hammer impact. This makes PIT also possible to estimate the depth of pile toe.


PIT does not required advance planning or access tubes, all it needs only an exposed flat surface. This makes testing questionable pile can be feasible to be done in a very short time. This means quality assurance with money and time benefits.
