Los Angeles, CA - March 28, 2007 -- Material Technologies, Inc. (OTC BB; MTTG.OB - News) ("MATECH" or "the Company"), announces the completion of an inspection of two bridges in Utah using its patented Electrochemical Fatigue Sensor System (EFS).

MATECH was retained by HDR Engineering, Inc. at the request of the Utah Department of Transportation (UDOT) to test two steel girder bridges in the Salt Lake City metro area using its EFS system. The bridges, in Spanish Fork, each had documented fatigue cracks in its center girder.

The objective of the EFS inspection and data analysis was to determine whether these known fatigue cracks were still growing under ambient traffic flow.  Six cracks were inspected on the northbound bridge and four cracks on the southbound lane

The results of this analysis lead to some important findings. Eight of the ten crack locations exhibited accelerated crack growth.  Of the other two, one is most likely growing at a very slow pace but conditions are such that accelerated crack growth can occur, and it should be carefully monitored. One location is not exhibiting any crack growth at all; thus repairs are not necessary at that location at this time.  The remaining crack locations are growing and should be repaired or retrofitted and then re-inspected to assure their crack growth has been arrested.

Additionally, as fatigue cracks are often difficult to detect, it was suggested that other similar girder connections be inspected with EFS on both sides of the girder web at the connection locations all along each bridge.  This detail is used universally along this bridge structure and is susceptible to fatigue cracking. These inspections will allow the agency to make repairs at these locations before they become more expensive problems, to more effectively deploy funds.

MATECH CEO Robert M. Bernstein commented: "We are extremely pleased to demonstrate our EFS to UDOT. I am confident that the EFS will help the State to detect growing cracks in their steel bridges, greatly increasing their transportation infrastructure safety and to realize cost savings in their bridge maintenance budgets."
