Pile integrity test is used to assess the continuity of piles. With this test, necking or bulging and uniformity of quality of concrete is checked.Piles that are doubtful for integrity are taken up for Dynamic load testing along with some piles which are ok. Method of Testing : There are Indian Standards for the pile integrity test & the most commonly used worldwide is Pile Integrity Test as per ASTM – D 5882 – 00, “Standard Test Method for Low Strain Integrity Testing of Piles”. Relevant clause from the said ASTM standard is reproduced below: Clause no. 5.2.3 : Placement of Transducers – The motion sensor should be placed at or near the pile head using a suitable, or temporary, bonding material (that is wax, vaseline etc.) so that it is assured that it correctly measures the axial pile motion.
