Impact-Echo Instruments is the world leader in developing and marketing impact-echo technology for evaluating concrete and masonry structures, catering to construction managers, DOT engineers, and forensic test consultants.

Our systems can measure thickness of concrete plates such as pavements, retaining walls, and tunnel walls, in compliance with ASTM Standard C1383-98a. They can also measure the depth of surface-opening cracks, and determine the location, depth and extent of cracks, voids, delaminations, honeycombing and debonding in plain and reinforced structures.

Unlike other companies, Impact-Echo Instruments specializes solely in Impact-Echo test equipment. In fact, we wrote the book about the technology and were among the first to commercialize it.
