TRMs or Turf Reinforcement Mats are synthetic-based mats that help prevent soil erosion or loss on steep slopes and drainage areas, while enhancing the vegetation which grows through them. As roots penetrate the mat, the root system becomes entangled within the TRM to further prevent soil loss and strengthen vegetation against major storm or high flow velocity events. Since water takes the path of least resistance, turf reinforcement mats serve as a shield for your exposed soil and seed, allowing stormwater to sheet flow over the mat while protecting everything beneath until it becomes established.
TRMs serve as an integration matrix for root systems to penetrate and lock-in, enhancing vegetation capabilities for high velocity applications. 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.
