Pile Integrity Tester (PIT) perform low strain integrity testing also known as sonic echo or pulse echo testing for assessing the condition of piles. The utilization of the Pile integrity tester is necessary for testing of building foundation piles, Dynamic Pile tests in highway engineering, and exposed top surface of constructions such as pillars and for non-destructive testing of railway piles. Pile Integrity Tester may also be used to test piles primary in the structure, such as those supporting existing bridges or towers.
