Concrete Bridge Deck Scanning

Unique. Revolutionary. Most accurate, technically advanced Impact Echo based system for structural condition assessment.

As a result of research funding from the National Cooperative Highway Research Program, Innovations Deserving Exploratory Analysis (NCHRP IDEA Contract No. 132), Olson Engineering developed the Sonic Surface Scanner (S3) which utilizes the Impact Echo (IE) test method as the S3 is pushed along a deck. Download the PDF to read more on the S3's ability to detect both top and bottom deck delaminations.

For decks with additional problems such as freeze-thaw cracking or alkali-silica reaction cracking damage, Spectral Analysis of Surface Waves (SASW) tests can be performed on bridge decks at the same time as Impact Echo tests to evaluate complete bridge deck integrity.
