The U.S. Army Corps of Engineers (USACE) discovered that its Rapid Repair Levee Breach (RRLB) facility was deteriorating due to sever, rain-induced erosion. The RRLB facility, a part of the Engineer Research and Development Center (ERDC), was designed to assist the USACE in determining practical and scientifically accurate engineering methods for evaluating the most challenging applications of flood protection materials.


This problem needed to be fixed immediately and after much research, a solution was found with Propex's ARMORMAX® 75 Engineered Earth Armoring Solution™. ARMORMAX® 75 consists of a High Performance Turf Reinforcement Mat (HPTRM) and Engineered Earth Anchors that work together to lock soil in place and protect against hydraulic stresses. This solution would provide the greatest and longest-lasting protection against further erosion.

Over just 2 days, more than 5,000 square yards of ARMORMAX was installed to prevent both basic and extreme erosive forces. The installation is fully vegetated and maintains its integrity despite heavy equipment traffic from regular mowing.
