Impact-Echo Instruments is the world leader in developing and marketing nondestructive instruments for evaluating concrete and masonry structures, catering for DOT engineers and forensic test consultants.

Our systems can measure thickness of concrete slabs such as pavements, retaining walls, and tunnel walls. They can also 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 the first to commercialize it.
