CHUM
Cross Hole Ultrasonic Monitor - with Tomography support

CHUM_System

CHUM supports Cross Hole Sonic Logging (CSL) as well as Single Hole Ultrasonic Testing (SHUT, SSL) and two- and three-dimensional Tomography (3DT, CSLT). 

This is the primary method used in the industry for for high resolution testing of large drilled piles (ACIP) 
Applicable standards: ASTM D6760-14, AFNOR NF P 94-160 (2000)

PET
Pile Echo Tester

 

USBPET_System

PET Uses the pulse-echo method (PEM, PIT) for pile testing. The pile 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 for quick quality control of a large number of piles.

Two PET versions are available: PT001 - PET USB Pro and PT002 - Bluetooth PET.

Applicable standards: ASTM D5882-08

PSI
Parallel Seismic Instrument

 

 

PSI_System

PSI uses the well-known Parallel Seismic method to establish the depth of existing foundations (specifically piles) where the superstructure precludes access to the pile heads.

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 m and filled with water. In unsaturated soils the tube should be firmly grouted in the hole to achieve good coupling with the surrounding soil.
