Quality Control of Concrete Piles and Foundations - Pile Integrity Test

The Problem

FPrimeC was retained by McClymont & Rak Engineers, Inc. to perform quality control of concrete piles using low strain pile integrity testing on newly cast concrete piles, Toronto, ON. Concrete piles were 1000 to 1200 mm diameter, and had 25 to 30 depth. The client was interested in quality control and inspection of integrity in these piles.


Quality Control of Concrete Piles – Pile Integrity Test

Low strain pile integrity test is a common non-destructive test (NDT) procedure for quality control and quality assurance (QC/QA) in deep foundation construction. The test can be used to identify physical defects (voids or discontinuity, referred to as pile integrity) in piles, or determine unknown length of existing deep foundations.

Low strain impact integrity testing provides acceleration or velocity and force (optional) data on slender structural elements (ASTM D5882). Sonic Echo (SE) method was employed for the integrity test on deep foundation and piles. The test results can be used for evaluation of the pile cross-sectional area and length, the pile integrity and continuity, as well as consistency of the pile material.
