Turf
Reinforcement Mats (TRMs) | | | | Turf Reinforcement Mats (TRMs) provide a permanent structural element to reinforce the turf and permanently increase its resistance to erosion. TRMs consist of various UV-stabilized synthetic fibers processed into 3-D matrices |
 | | 1. TRMs reinforce turf to extend the thresholds of vegetation to the performance limits traditionally addressed with hard armor. |
 | | 2. The black mat in the channel bottom is a permanent TRM, degradable erosion control blankets line the side slopes. |
 | | 3. The TRM provides reinforced vegetation while the erosion control blankets do not. |
 | | 4. The reinforced turf is on the left, un-reinforced turf is on the right. |
 | | 5. Standard TRMs are used in channels, |
 | | 6. and slope applications. |
 | | 7. High Performance TRMs are used in more demanding applications such as pipe outlets, |
 | | 8. and roadsides. |
 | | 9. TRMs prevent sediment pollution, |
 | | 10. and provide cost savings as well. |
 | | 11. TRM applications eliminate the undercut associated with traditional Riprap applications. |
 | | 12. By reducing the undercut excavation, one roll of a TRM can eliminate as many as 12 trucks. |
 | | 13. Reduced Right of Way: For the same volume of water, a TRM lined channel will require less Right-of-Way. |
 | | 14. TRM linings allow the same amount of water to run wider and shallower, reducing erosive forces providing greater channel capacity. |
 | | 15. Riprap applications can be eyesores that are dangerous, easy to vandalize, difficult to maintain and tend to breed vermin and snakes. |
 | | 16. TRMs provide a safe, pleasing finished application that is hard to vandalize, easy to maintain and won’t breed vermin and snakes. |
