InstaTurf High-Performance Erosion Control Mats
Turf reinforcement mats (TRMs) have long been used to increase the erosion resistance of vegetation compared to rock riprap and other hard armor linings. However, older, conventional TRM systems do not provide this high level of erosion protection until vegetation maturity, leaving entire projects at risk, vulnerable to water damage and failure. The innovative InstaTurf ShearForce products solve this problem once and for all. Patent pending InstaTurf™ ShearForce10™ and Shearforce12™ high-performance erosion control products reduce risk by virtually eliminating erosion under very high-flow conditions from the very first day of installation.
ShearForce10™ High Flow Erosion Control Turf Reinforcement Mat
This new, patent pending erosion control product consists of a green, simulated turf monolithic polyethylene structure, backed with a specially engineered geotextile fabric. The simulated grass blades of the turf deflect rainfall impact and flow-induced shear stress away from the fabric backing and the underlying soil. The fabric backing is designed to hold fine soil particles in place, while facilitating seed germination and emergence for exceptional immediate erosion control and full vegetation establishment. ShearForce10™ is available in convenient 3 ft. wide and 6 ft. wide rolls for quick and easy installation.
ShearForce10™ offers the performance of reinforced turf from day one that is on par with large riprap. Proven in ASTM D6460 unvegetated channel testing to drastically reduce soil erosion without vegetation at flow-induced shear stresses exceeding 11 lbs./sf, ShearForce10™ offers more than three times the immediate channel erosion protection of conventional TRMs. Once vegetated, ShearForce10™ permanently protects the soil base, reinforces vegetation roots and increases the long-term permissible shear stress of the vegetated system.
-
- Reinforced turf performance from day one, no waiting on vegetation for effective erosion protection at shear stress > 10 lbs./sf
- Immediate erosion control equivalent to large rock riprap and other hard armor, at less than half the cost
- Simple installation, just lay and anchor it, no heavy equipment required
- Aesthetically pleasing, green grassed-in finished look
- Environmentally friendly, facilitates water filtration and infiltration
- Highly UV stable and weather resistant, for permanent strength and durability
- ShearForce10™ is available in convenient 3 ft. X 45 ft., 48 lb. and 6 ft. X 45 ft., 96 lb. rolls for easy installation
-
- High flow channels and extreme slopes requiring maximum erosion protection before, during and after vegetation establishment, including channels with constant low-flow discharge
- Drainage swales and slopes where an immediate vegetated look is desired and/or vegetation is slow to establish
- Projects in arid areas where vegetation establishment is very slow and sparse
- Moderate flow culvert outfalls, downchutes, spillways and dams
- Detention basins, lake shorelines, streambanks, canals, and levees
ShearForce12™ High Flow Scour Control Transition Mat
The patent pending ShearForce12™ high flow scour control transition mat incorporates a ½ inch thick, weather resistant, perforated rubber core layered between a green, simulated turf monolithic polyethylene structure and an engineered geotextile fabric. Unlike other scour transition mats that require a separate TRM underlayment for sufficient initial erosion protection, ShearForce12™ is an all-in-one, 3 ft. X 4 ft., 30 lb. panel, that’s simply installed directly on top of the seeded soil surface.
The simulated grass blades of the turf structure are designed to deflect rainfall impact and flow induced shear stress away from the apertures in the rubber core and the fabric backing. The turf structure further increases surface roughness when used in flow transition areas to slow water flow and reduce turbulence. The rubber core provides an enhanced ballast effect and flow impact resistance, while vegetation grows up through its 1.5 inch apertures.
Proven in ASTM D6460 unvegetated channel testing without vegetation to virtually eliminate soil erosion at flow-induced shear stresses exceeding 12 lbs./sf., ShearForce12™ mats offer immediate as well as permanent erosion protection equivalent to 36 inch rock riprap. ShearForce12™ mats are ideal for areas subject to substantial wave action and very turbulent, high shear stress water flows.
