The design prepared by VTN West and Dr. Chang included the Pyramat high performance turf reinforcement mat (HPTRM), vegetation for aesthetic and habitat creation purposes, and 14 ft deep cut-off walls at the upstream end, downstream end, and incrementally spaced throughout the project. A grouted rip-rap combination design was used at locations designated to have high scour potential. The tan colored Pyramat was chosen for this canyon channel application to match the intended future native vegetation. The Pyramat® high performance turf reinforcement mat (HPTRM) was selected because of the aesthetic, cost-saving, water quality benefits and performance over the other alternatives. Pyramat® outperforms other turf reinforcement mat products because of its long-term design life through superior tensile strength, UV protection, flexibility, woven technology and X3® fiber technology, which allows for faster vegetation growth.
