Measure slab thickness.

An acoustic non-destructive test method.

Introduction

Testing with the Impact EchoPCTS use Olson Instruments NDE360. A CTS technician strikes the surface of a structural element with a tuned hammer (a steel ball of specific size) to produce a pressure wave (P-wave) pulse in the material of up to 90kHz that propagates into the structure and is reflected by internal discontinuities or external surfaces.

Applications

PCTS Technicians are available to:

  • Measure Slab Thickness

  • Locate position, extent and depth of:

    ␣ Cracks ␣ Voids ␣ Delamination's ␣ Honeycombed Concrete ␣ Ungrouted Metal Tendon Ducts

  • Strength via acoustic velocity
