Impact-Echo can be used for plate-like concrete structural members such as slabs, slab-on-grade, concrete pavements, decks, walls and tunnel linings.

Estimate the Thickness of thin concrete slabs and walls:

* Bridge Decks

* Parking Garage Slabs

* Tunnel linings

Impact-Echo Detect Delamination

Identify Location and Extent of Voids and Delamination:

* Bridge Decks

* Parking Garage Slabs


Impact-Echo Detect Voids in Post-Tensioning Ducts

Detect Voids in Grouted Tendon Ducts:

* Post-Tensioned elements


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.
