Los Angeles, CA - November 6, 2007 --Material Technologies Inc. (OTCBB: MTTG -News), an engineering company that engages in the research and development of technologies to monitor and measure metal fatigue, today announced that they have nearly completed the inspection of nine bridges throughout the State of Pennsylvania using the company’s proprietary Electrochemical Fatigue Sensor (EFS) system. The inspections were intended to determine if existing cracks are growing, if cracks exist that were not previously documented and to help the state prioritize repair funds. Additionally, the inspections are helping Pennsylvania determine the most effective retrofits to stiffen bridge members.

The EFS is the only practical nondestructive test method that can immediately determine whether a crack in a bridge structural member is growing or not. If it is growing, plans can be made to repair or modify the structure to halt the crack growth. If it is not growing then the crack can be safely ignored for the time being. EFS can also be used after the repair or retrofit is implemented to confirm that the inspected crack location is indeed no longer growing.

“Being able to prioritize repairs to these bridges is an invaluable result of the EFS inspection,” said Robert M. Bernstein, CEO of MATECH. “Also, by being able to immediately verify the effectiveness of repairs, we help to eliminate the ‘wait and see’ method. This kind of objective information allows bridge owners to sleep at night,” he added.

Pennsylvania has over 7,500 steel bridges in its inventory. The national rate of structurally deficient bridges is nearly 30%. Material Technologies currently has an on-call contract with the state of Pennsylvania to deploy its EFS system on steel bridges across the state.
