High Performance Turf Reinforcement Mat (TRM)
PioneerTEX high performance Turf Reinforcement Mat is non-degradable, soil and seedbed cover available in variable thicknesses similar to
Erosion Control Blankets(ECB). They are composed of UV stabilized synthetic PP Monofilaments, nettings and/or mesh that secure plant roots, stems and soil. These permanent structures consolidate and protect the soil and prevent it being washed away. Once established, turf reinforcement mats can withstand velocities and shear stress values up to 4.6m/sec and 49kg/m2, respectively. TRMs also reduce sheet, rill and channel erosion by up to 90 percent. Turf Reinforcement Mats provide:
− Erosion protection
− Highly UV resistance
− High strengths for durability
− Superior permeability
− High flow rates
− Unique Weave ensures excellent separation factors that control filtration and drainage

Applications – Turf Reinforcement Mat
Turf reinforcement mats are usually used in conjunction with grass on longer, steeper slopes in higher velocity ditches and channels; along shorelines for permanent scour prevention; for armouring at culverts; and to reinforce vegetation on road and railway embankments. Some of the thinner TRMs are designed to be placed directly over seeded bare soil areas, while thicker open-celled/open weave products may be staked down first, then seeded and covered with topsoil.
Turf reinforcement mats are typically used when slope and channel conditions exceed the capabilities of erosion control blankets such as 3D Coconut fiber turf reinforcement mat, but are not severe enough to justify terracing or geocell in slope applications, or harder armouring (e.g., articulated block, riprap, Concrete Mat Cloth, etc.) within stormwater channels. TRMs may not be suitable for arid areas where vegetation may not establish or survive.
Installation – Turf Reinforcement Mats
Typical installations involve rolling out and anchoring the turf reinforcement mat to ensure intimate contact with the soil surface. They can be applied directly over a freshly seeded soil surface and allow the vegetation to grow through the mat. Other types are first anchored to the ground and then covered with a mix of fine soil and seed.
Once installed, vegetation and soil shield the synthetic components from UV radiation and maintain the structural integrity of the mat.
