Low Strain Dynamic Pile Test

The Pile Integrity Tester (PIT) determines if a pile or shaft is free of major cracks and voids. It may be used on most concrete or wood foundations. The PIT may also be used to test piles integral in the structure, such as those supporting existing bridges or towers, and may assess their length.

The PIT performs the wave equation-based non-destructive test known as Pulse or Sonic Echo Test, or Low Strain Dynamic Test. With the PIT, the test is performed fast, potentially making it possible to test every pile on a job site.

The PIT test consists of attaching one or two accelerometers to the foundation, and using a hand held hammer to impact it. The PIT collects the acceleration data and displays curves that reveal any significant changes in cross section that may exist along the shaft. The PIT-W software post processes the data and generates reports.
