PSI uses the well-known Parallel Seismic method to establish the length of existing foundations (specifically for a pile or deep foundations) where the superstructure (i.e. existing building) precludes access to the pile heads.
It is sometimes the only pile integrity test that can be performed.
For making reuse of old piles
Easy to run test
Measures only the pile length under a structure
Standard compliant with
AFNOR NF P94-160-3
The test requires the installation of a plastic access tube in parallel and as close as possible to the tested pile. The tube should be carried down to a depth exceeding the assumed pile length by a margin of 8-10 meters and filled with water.
In unsaturated soil the tube should be firmly grouted in the hole to achieve good coupling with the surrounding soil.
When sustainability requires old pile reuse, PSI offers a way to measure what pile length is real there

3 Dimensional Tomography
While normal (1D) CSL can only show the depth of an anomaly, tomography can help in the visualization of the shape, size, and location of anomalies. It is an analysis and presentation method of captured CSL data, that projects the logged results into two dimensional (2D) plane or three dimensional (3D) body.
Pile Integrity Tester
PET is used to test the integrity of deep pile foundations. PET Uses the pulse-echo method (PEM) for pile integrity testing (PIT). A pile test starts when the pile top is struck with a hammer, and the PET accelerometer records the reflected waves, which are displayed as a reflectogram.
