Standard Duty Turf Reinforcement Mats (TRMs) are synthetic, non-degradable soil and seedbed covers of variable thickness designed to provide short-term protection against stormwater and wind erosion, permanent support for vegetation on slopes, and permanent armoring and vegetation support for ditches, swales, and channels.
Standard Duty TRMs serve as an integration matrix for root systems to penetrate and lock-in, enhancing vegetation capabilities for high velocity applications. Standard Duty TRMs are typically less than half the cost of rock riprap, and 25% the cost of concrete. They are much easier to transport and install with no heavy equipment required. They can be maintained with standard mowing equipment for easier long term maintenance to produce an aesthetically pleasing, environmentally friendly, ecologically functional vegetated solution.
