PET Uses the pulse-echo method (PEM, PIT) for pile integrity testing. A pile test starts when the pile top is struck with a handheld hammer and the PET digital accelerometer records the reflected waves on the computer screen. The resulting signal (reflectogram) readily provides information regarding the pile's length and integrity.
This is the primary method used in the industry for quick pile integrity test, to control the quality of piles on a site with a large number of piles.
Two PET versions are available: PT001 - PET Pro USB and PT002 - PET Bluetooth.
Fully supports the following standards:
[ASTM D5882-16], [AFNOR P160-2,4]
AFNOR NF P 94-160-1 (2000)
BIT quickly and accurately measures the inclination (verticality) of
BIT is based on gyro technology, to enable simple, fast and productive inclination testing, with a very lightweight system which can be handled by a single operator
ASTM D8232 - 18
PSI uses the well-known Parallel Seismic method to establish the depth of existing foundations (specifically piles) where the superstructure (i.e. exsiting building) precludes access to the pile's head.
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 8-10m and filled with water. In unsaturated soils the tube should be firmly grouted in the hole to achieve good coupling with the surrounding soil.
