INTEGRITY TESTING

Integrity testing is carried out in order to identify anomalies in piles that could be of a structural importance.

How do they work?

There are a variety of testing procedures available including the ‘impulse response’ and ‘sonic echo’ methods. They work by sending a stress wave down the pile after it has been struck by an impact device. The reflection, when analysed in conjunction with the knowledge of the soil conditions and pile dimensions, provides information on the structural quality.

When are tests carried out?

When the concrete has reached two thirds of its design strength, or approximately seven days for most piling mixes, the pile may be trimmed. At this point, and prior to the placement of any reinforcement for the ground beams and pile caps, the piles may be tested. Please note that we require three working days notice to arrange the testing.
