c~~B~Na Enkamat 7020 R2M
Root Reinforcement Mat
Description Enkamat® 7020 is athree-dimensional turf reinforcement mat {TRM) made of continuous
monofilaments fused at their intersections.. Ninety-five (95%) percent of the Enkamat is
open and available for soil, mulch and root interaction with filaments, creating the mast
effective Root Reinforcement Mat (R2M) available. Enkamat is manufactured from nylon
to eliminate the buoyancy factor associated with submerged conditions and provide per-
manent TRM protection in vegetated channels as well as on slopes.
Recommended Permanent erosion control for Green (vegetated) channels with expected shear
Applications stresses s 10 psi.
. Permanent erasion control for moderate to steep slopes (<_ 1.5H:1 V).
. Support and enhance pertormance of Ecosystem plants.
. Substrate for hydraulically applied Banded Fiber Matrix (BFM) and other mulches for
erosion control applications where low water flow and low to moderate shear stresses
are expected
