Pile Integrity testing

Pile Integrity testing

Pile Integrity testing is undertaken to provide the confidence that the integrity of piles or shafts most commonly filled with concrete are free of major defects such as cracks and voids, prior to construction of the superstructure or for those supporting existing structures including bridges and buildings.
Nicholls Colton Group test using the latest Pile Echo testing technology by the Pulse-Echo method to provide quick pile integrity analysis to ensure quality control and investigate condition of existing piles. The PET is fully compliant to ASTM D5882 – 07(2013) Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations and is effective on extremely long piles.

The signal from a compression wave is collated and analysed by the PET’s digital accelerometer to provide real time data detailing the length and shape of the pile. Assessment is undertaken by analysis of the time taken for the reflective wave to travel along the length of the pile. This test is suitable to analyse the integrity of large numbers of piles quickly and efficiently.
