PIT performs Low Strain integrity testing, also called Sonic Echo or Pulse Echo Testing. The PIT may be used for auger cast-in-place (CFA) piles, drilled shafts, driven concrete piles, concrete filled pipes and timber piles.
The Acoustic Concrete Tester determines the thickness of structural elements such as concrete pavements, slabs, retaining walls, tunnel liners, foundation footings, and more. In addition, the ACT may identify defects such as delaminations, spalls and horizontal flaws. The ACT tests structures as thin as 75 mm and as thick as 600 mm.
Pull-off testing is one of the most widely used test methods in the construction industry. This is reflected in the huge number of standards dedicated to the method.
