Pile integrity testing

A low strain integrity pile test is a rudimentary test performed with a hand-held hammer and a pile sensor. Such a test can:

  • Reveal potential pile defects such as cracks, voids, necking, or soil inclusions,
  • Determine unknown pile lengths.

We perform two types of tests: the sonic-echo test (also called the pulse-echo test, or simply the integrity test) and the transient response test (also called the impulse response method or the impedance test).

The sonic-echo test is standardised following the NF P 94-160-2 norm and the transient response test following the NF P 94-160-4 norm. For both types of test, we also follow the ASTM D5882 standard.
