Side-by-Side Field Specification Matrix

Engineering Parameter Rolled Straw / Jute Erosion Blankets ViscoLok Hydraulic EFM Matrix
Environmental & Aquatic Toxicity Plastic netting creates wildlife entanglement risk & microplastic debris Fully Microplastic-Free, Biodegradable & Wildlife Safe
Tank Mix Yield & Anti-Foam High labor costs: 20-30 man-hours per acre for trenching & stapling Hydraulic application: 1-2 hours per acre via commercial hydroseeder rig
Fisheye Clump Mitigation Blankets tent over rocks/clods causing subsurface water erosion Direct soil surface contour contact on rough/rocky slope terrain
SWPPP & Rain-Fast Compliance Risk of sub-surface rill erosion undermining blanket anchors Seamless soil-matrix interlock prevents subsurface washouts

Financial Callback Risk Analysis (5-Acre Slope Example)

Stop losing $15,700 on legacy washouts. Switch to OHRA and instantly save up to $15,000 per 5-acre site.

Your Legacy Washout Costs
  • Equipment and Labor: $3,500 – $5,000
  • Seed and Fertilizer Replacement: $2,200 – $3,500
  • EPA Stop-Work Fines: Up to $10,000 / day
  • Your Baseline Liability: $15,700+
Your OHRA Project Economics
  • Matrix Shear Bond: Kill your washout risk
  • Active Polymer Yield: Stop material waste on fisheyes
  • SWPPP Compliance: Produce zero toxic runoff
  • Your Cost Reduction: $12,000 – $15,000 per 5-acre site
