The Pile Echo Tester (PET) is a user-friendly, highly flexible solution for testing a large number of deep foundations quickly and accurately. Requiring little-to-no training, PET is a modular, computer- independent system that connects to any laptop or PocketPC via wireless Bluetooth. The PET system utilizes the pulse-echo method. To test a pile, the user strikes it with PET´s lightweight hammer. The resulting signal, or reflectogram, is captured and transferred to the computer by PET´s digital accelerometer, providing real-time information about the length and shape of the pile.

The CHUM uses the Crosshole Sonic Logging (CSL) method to perform high-resolution quality control on deep foundations. The system uses an ultrasonic wave sent from an emitter to a receiver which is pulled through water filled access tubes embedded in the concrete. The measured arrival time and energy are directly related to concrete quality. Additional methods supported by the CHUM are Single Hole Ultrasonic Testing (SHUT) and Tomography (two- and three-dimensional).

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.

SAM measure changes in pre-stressed soil and rock anchors force. Pre-stressed soil and rock anchors are widely used in civil engineering to resist the horizontal pressures acting on retaining structures. With time, anchor force may decrease due to relaxation and creep. As a result, anchored elements may displace excessively and eventually fail. Therefore, it is extremely important to have suitable permanent means to measure the residual force and verify that the anchor is functioning properly and according to design. Advantages: Low cost, accurate, integral, simple installation and remote monitoring

All piling specifications prescribe the allowable deviation of the pile axis from the vertical. FHWA rules, for instance, limit the pile inclination to 20 mm/m, or 2%. The ICE (UK) specifications allow a deviation of not more than 1:75 or 1.33%. Similarly, these documents also set down the allowable deviation of raked piles. In diaphragm walls, the specification is typically even more restrictive. Unlike traditional systems, BIT uses the auger/bucket itself as the centralizer. Eliminating the need for a heavy-to-move system. The BIT enables fast and accurate determination of inclination in both dry and wet boreholes. Large boreholes and diaphragm walls may be quickly tested several times during drilling to enable real-time corrections.
