InstaTurf® ShearForce Products Excel in Large-Scale Performance Testing
The immediate erosion control performance of InstaTurf ShearForce™10 and ShearForce™12 products 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
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.
