Estimate the Thickness of thin concrete slabs and walls
Identify Location and Extent of Voids and Delamination
Detect Voids in Grouted Tendon Ducts

How Does It Work ?

Impact-Echo uses the principles of stress-wave propagation in plate-like elements to study the internal voids and defects in concrete members. The testing procedure is completed in three simple steps.

✅ A small ball impactor is used to strike the test point.

✅ Collect the echoes reflected from boundaries, voids, and delamination

✅ Analyze the test results (time domain and frequency domain), and develop contour maps of sub-surface defects.
