InstaTurf™ ShearForce10 Erosion Control Turf Reinforcement Mat

Product Specification

 

Simulated Turf High Flow Erosion Control Mat

 

The simulated turf high flow erosion control mat shall provide the immediate finished look of natural grass along with the high flow erosion protection of large rock riprap, while establishing permanently reinforced vegetative cover. The mat shall consist of a UV stabilized, monolithic polyethylene simulated
turf structure with approximate 7/16 inch by 5/8 inch rectangular apertures, backed with an engineered lightweight polyester geotextile. The geotextile must be dense enough to retain fine soil particles and seed, yet open enough to allow seedling emergence. The mat shall have an unvegetetated permissible shear stress rating, as determined by ASTM D6460 large-scale channel testing, of 10 lbs/sf or greater for immediate as well as long-term erosion protection against high shear stress water flow. The high flow erosion control turf reinforcement mat shall have the following characteristics and dimensions, and meet or exceed the minimum physical and performance properties as specified below.
