Pennsylvania Moves Forward with Bridge Crack Detection System
Following the successful nondestructive testing of three bridges in Pennsylvania, the Pennsylvania Department of Transportation (PennDOT) has prepared an on-call contract with Materials Technologies, Inc. (MATECH) for the entire state.

Officials were impressed with the work and cost effectiveness of the results and believe MATECH has already saved them on the order of $50,000 as well as possibly avoiding the closure of one of their main bridges, saving more money and potentially lives. Because the EFS can find growing cracks and an indication of their rate of growth, PennDOT told MATECH they can sleep better at night knowing if a known crack is growing or not.
