A Step Above Temporary Erosion Control Blankets

North American Green’s SC250 is comprised of a permanent, high strength three-dimensional matting structure incorporated with a straw/coconut fiber matrix. It is designed to provide both extended term, pre-vegetated erosion protection and permanent turf reinforcement in a wide variety of applications, including severe slopes, high flow channels and stream banks.

The straw/coconut fiber matrix enhances the permanent matting’s initial mulching and erosion control performance for up to 24 months. Proven in laboratory and field research, the permanent matting’s high strength 3-D structure increases the shear resistance of vegetation up to 10 lbs / ft2 (480 Pa).

With even the toughest stand of unreinforced grasses typically failing at shear stress levels of 3.7 lbs / ft2, the SC250 more than doubles the shear resistance of any vegetation. This enables the SC250 to be used in many applications where rock riprap and concrete were once the only viable alternatives.
