WINMAT 620 is a 3-dimensional turf reinforcement mat (TRM) made of continuous monofilaments fused at their intersections. 95% of the WINMAT 620 is open and available for soil, mulch, and root interaction, creating the most effective root reinforcement mat (R2M) available. WINMAT 620 is manufactured from nylon to eliminate the buoyancy factor associated with submerged conditions and provides permanent TRM protection in vegetated channels as well as on slopes.

WINMAT 620 is recommended for the following applications:

  • Permanent erosion control for vegetated channels with expected shear stresses ? 17 psf.
  • Permanent erosion control for moderate to steep slopes (?0.5H:1V).
  • Support and enhance performance of ecosystem plants.
  • Excellent substrate for hydraulically applied mulches for applications where calculated hydraulic forces exceed the threshold of the mulch by itself and/or unreinforced vegetation.
  • Meets requirements of FHWA FP03 Type 5C TRM
