On April 20th, 2004 Infrastructure Defense Technologies utilized Karco Engineering's expertise to perform a U.S. Department of State K12 crash test using a 15,000 pound truck traveling at 50 mph down a 900 foot concrete runway into a standard Metalith™ barrier that was 40-feet long, 10-feet high, and 8-feet thick impacting the wall at a 90° angle.

Truck penetrationThe truck cab was completely destroyed, the Metalith wall, as a unit, moved 0 inches, and penetration by the truck bed was negative 48 inches!

Subsequent to the testing performed by Karco Engineering, Infrastructure Defense Technologies Metalith barrier wall was certified as a K12 product by the U.S. Department of State.
