Low Strain PIle Integrity Test <\/h2>\n \n <\/div>\n \n
\n

Low Strain Integrity Test, also known as Pile Integrity Test (PIT) is a non-destructive testing method for integrity assessments of concrete piles (augured cast-in-place piles, drilled shafts or driven piles). If major defects exist, test results may be interpreted to estimate the magnitude and location of defect.<\/p>\n\t\t

Because of the simplicity, speed of execution and relatively low cost, PIT may be performed on 100% of the piles on a given job site.<\/p>\n\t\t

The methodology involves a small impact by hand-held hammer on the pile top that generates a compressive stress wave in the pile. The stress wave propagates down the pile shaft and is reflected when it encounters either the toe or a non-uniformity of the shaft. These reflections cause a change in the acceleration signal measured on the pile top, which is picked up and processed by the Pile Integrity Tester (PIT) equipment and interpreted using PIT-Software.<\/p>\n\t\t

STS is equipped with Pile Integrity Testers from Pile Dynamics, USA to perform Low Strain Pile Integrity test on piles.<\/p>\n\n
