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 impulse response test (also called the transient response test, the sonic mobility method, the impedance test, or the MIMP for méthode impulsionnelle).

We perform the sonic-echo test following the NF P 94-160-2 standard and the impulse response test following the NF P 94-160-4 standard. Both tests also comply with the U.S. ASTM D5882 norm. Furthermore, our tests follow the U.K. ICE Specification for Piling and Embedded Retaining Walls (3rd edition, chapters B15-C15).
