Los Angeles, CA - August 10, 2007 --Material Technologies Inc., (OTCBB: MTTG.OB - News;) stated that their patented Electrochemical Fatigue Sensor (EFS) technology, which finds very small growing fatigue cracks in metal structures, is able to reduce much of the uncertainty in metal bridge inspections. Reliably knowing whether a fatigue crack is growing or not adds a high degree of certainty to the ability of a bridge to maintain its structural integrity.

A growing crack should be reinforced or repaired within a reasonable time; a non-growing crack can likely be safely ignored until the next inspection. Thus EFS can make best use of available repair funds. Following a repair, EFS can immediately verify that the repair is effective, that is, the crack is no longer growing.

MATECH recently used its EFS on several bridges in Pennsylvania. PennDOT, the agency responsible for such repairs, likes this technology. "It costs us money, but we can sleep at night knowing the repair is adequate," one of their officials said. There are also very significant potential cost savings by identifying which cracks can be safely ignored.

The EFS works like a heart EKG. It can detect fatigue cracks too small to see with the naked eye, and can accurately determine if a crack is growing or not. The Federal Highway Administration (FHWA) has stated that 90% of fatigue cracks are missed by inspectors using visual methods, and that 56% of bridge ratings based on these visual inspections are incorrect. There is an obvious need for improved inspection methods, which are less dependent on inspectors' subjectivity.

Robert M. Bernstein, MATECH's CEO, said, "MATECH has performed more than twenty field tests on actual highway and railroad bridges around the country using EFS, so its history and reliability in detecting growing cracks are well known. We have every confidence that our EFS can save many repair and rehabilitation dollars by its timely use, as well as avoiding lane and bridge closures which can have a devastating effect on local commerce, not to mention avoiding potential tragedies of bridge failures."
