Soft Armor Hybrid Turf


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. 

Color: Grass green

Roll Sizes:

  • 3ft x 45ft (135sf)
  • 6ft x 45ft (270sf)

InstaTurf ShearForce10 Details

  • Available in 3ft x 45ft, 49 lb rolls and 6ft x 45ft, 99 lb rolls for easy handling.
  • Aesthetically pleasing natural grass-like appearance
  • Typical installed cost savings of 50% – 65% vs rock riprap, tied concrete block mats, and other hard armor materials
  • Much smaller carbon footprint than hard armor materials
  • Worry-free rock-like erosion protection under flow-induced shear stresses > 10lbs/sf, from day one of installation
  • Highly UV stable and weather-resistant
  • Simple installation, just lay it over seeded area and anchor it with standard staples, stakes or pins
  • Grows and reinforces natural vegetation for permanent stabilization and mower-friendly maintenance

3ft x 45ft roll weighing 45lbs

6ft x 45ft roll weighing 99lbs

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 unvegetated 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 immediate erosion control performance of InstaTurf ShearForce™10  was quantified in ASTM D6460 Large-scale Unvegetated Channel testing at TRI Environmental’s Denver Downs research facility

  • Shear Stresses up to 12 lbs/sf
  • 2ft wide x 40ft long channel flume, Loam soil bed on 20% gradient
  • Unvegetated ShearForce Products DID NOT fail at highest achievable flow discharge
  • Average Cumulative Soil Loss – Approx. .1 — .2 Inches (ASTM failure point .5 inches)
  • 3 Separate test plots with (4) consecutive 30 min flow events per plot
  • Mats installed with 8-inch wire staples at 3.8/SY
  • Discharges up to approx 50 CFS
  • Velocity > 24 ft/sec

Average Cumulative Soil Loss – Approx .1-.2 Inches (ASTM failure point .5 inches)
Unvegetated ShearForce Products DID NOT fail at highest achievable flow discharge

Results from initial and subsequent rounds of ASTM D6460 unvegetated large-scale channel testing were very impressive. But don’t just take our word for it… download the results and see for yourself.
