A hybrid-turf instant armor mat for protecting severe slopes, channels, streambanks and shorelines. The hybrid-turf instant armor mat provides the immediate finished look of natural grass along with the high flow erosion protection of large rock riprap, while establishing permanently reinforced vegetative cover.Added ballast to prevent uplift in turbulenceIn culvert and pipe outfalls and other areas subject to turbulent water flow, conventional mattings can be lifted off the soil surface between anchor points and allow erosion to commence. The ShearForce12’s ½-inch high specific gravity perforated rubber core will not float and adds nearly 2.5 lbs/sf of ballast to the mat to resist uplift. This additional ballast ensures that the mat performs as expected in the worst of conditions while still promoting vegetation when the sun is shining.Color: Grass greenPanel Sizes:3ft x 4ft (12sf)
