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.

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.

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.
