Flexterra® HP-FGM™ has demonstrated nearly perfect erosion control performance—even on slopes as severe as 0.25H:1V. It immediately bonds to the soil surface, and has proven to be greater than 99% effective upon curing. Its flexible, yet stable matrix features greater wet bond strength, yielding increased sheet flow resistance. In addition to minimizing soil loss, the turbidity (NTU) of runoff is greatly reduced. In large scale testing, Flexterra HP-FGM reduced effluent turbidities of sandy loam soils to less than 100 NTU.
