![]() ![]() The pile head with sound concrete shall be available for testing. The data is displayed on the field for preliminary evaluation and interpretation, and a field printout is possible. The equipment includes a sensitive accelerometer and a non-instrumented hammer, in addition to the device. ![]() This is currently best equipment available worldwide with use in most countries across the world and Geo Dynamics operates more than 15 such equipments in India.

Standard Test Method for Low-Strain Integrity Testing of Piles. The method also evaluates the bulge or bulbs inside the pile but a bulb is not considered as a defect. The purpose of testing is evaluate the pile for potential defects that maybe caused due to necking, honey-combs, soil inclusions, cold joints etc. Reports shall be submitted for each pile as per the method and requirements described below. This shall be done after the piles have been chipped upto sound concrete level (cutoff level in most cases) and before tying the reinforcement cage. The current scope of work involves conducting low strain integrity testing on 100% of the piles at the project site. The number of tests shall be decided by the engineer to the project. The test procedure is standardized as per ASTM D5882 and also forms part of various specifications and code provisions worldwide. It is known as “Low Strain” method since it requires the impact of only a small hand-held hammer and the resultant strains are of extremely low magnitude. The method evaluates continuity of the pile shaft and provides information on any potential defects due to honeycombs, necking (cross-section reduction), potential bulbs, sudden changes in soil stratum, concrete quality in terms of wave speed etc. Pile Integrity Testing (PIT) is a Non-Destructive integrity test method for foundation piles.
