The Piletest BIT borehole inclination tester

BIT

BIT measures the verticality of open boreholes and all kinds of deep foundations: drilled shafts, precast piles, H piles, and even sheet piles.

BIT uses the auger/bucket as the centralizer in the borehole. Eliminating the need for a heavy-to-move system. A special centralizer is used to lower the sensor into a standard access tube of an existing pile. 

  • No expensive inclinometer tubes

  • Lightweight 1-person simple operation  

  • Works on any diameter

  • ASTM D8232-18 Standard compliant

 

Applications

Measurement of inclination is required to ensure the deep foundation (vertical or raked) stays within the allowable deviation, typically 2%. More stringent requirements are often specified for diaphragm and secant walls to ensure that there are no gaps in the wall and that the bottom of the wall is in the correct location. Inclination measurement is also utilized in deep wells for various applications.

Easy to Operate Inclination test for Borehole and Pile Foundations, Diaphragm and Secant Walls

The Piletest PSI parallel seismic instrument for pile foundation

PSI

Parallel Seismic Instrument

PSI uses the well-known Parallel Seismic method to establish the depth of existing foundations (specifically for a pile or deep foundations) where the superstructure  (i.e. existing building) precludes access to the pile heads.

The Piletest CHUM crosshole ultrasonic monitor CSL

CHUM

Cross Hole Ultrasonic Monitor

The CHUM uses the Crosshole Sonic Logging CSL testing method to perform high-resolution quality control of deep foundations. It is used mainly for large-size deep pile foundations, where pile integrity tester like PET is not suitable.

The Piletest PET a pile integrity test equipment PIT tester

PET Bluetooth

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.
