The Profound SIT-series meets the constructions industry’s demand for professional Sonic Integrity Testing of concrete piles. Pile quality is often determined by performing a low strain integrity test directly after pile driving or within days after installation of cast-in-situ piles. In some cases, it is difficult to distinguish the soil response, and the (pile) toe response.Pile Integrity Tester is a widely used instrument for testing the quality of concrete piles in a non-destructive way before they are incorporated in the final foundation plan. When the toe reflection is not evident, integrity evaluation may not be conclusive.Ĩ. Pile integrity is generally not suitable for testing steel sheets, H-section, or unfilled pipe piles.ħ. It is not effective in evaluating sections of piles below cracks that crosses the entire cross-sectional area of the pile.Ħ. This test is not effective in piles with highly variable cross sectionsĥ. Integrity testing of cross sections below a major crack (that crosses the entire cross-sectional area) is not possible.Ĥ. Integrity Testing cannot be conducted over pile caps.ģ. Limitations of Pile Integrity Testġ. Pile Integrity Test does not provide any information on the load bearing capacity of piles and deep foundations.Ģ. The following section summarizes the main limitations of the pile integrity method. However, the method has certain limitations, some of which are inherent. Pile Integrity Test (PIT) provides useful information about the above-mentioned aspects of piles. Determining the integrity and continuity of piles Evaluate pile cross-sectional area and length ģ. Evaluate unknown length of piles, or elements Ģ. The test has been standardized as the ASTM D5882: Low Strain Impact Integrity Testing of Deep Foundations. In this article, we will review some of the main applications and limitations of pile integrity test. The test may not identify all imperfections, but generally can identify major defects within the effective length. A hammer (regular or instrumented) is used to impact the pile surface and induce acoustic waves ( WATCH: How PIT is Performed?). The method works based on measuring and analyzing the velocity (required) and force (optional) response of pile. The method works best for long structural component such as driven concrete piles, cast-in place concrete piles, concrete filled steel pipe piles, timber piles, structural columns. Pile Integrity Test can be used to determine the integrity of piles.
