VMax® Permanent Turf Reinforcement Mats

The top of the line P550® TRM has a polypropylene fiber matrix augmenting the permanent netting structure with permanent mulching and erosion control performance. Unvegetated, the P550 TRM reduces soil loss to less than 0.5 in. (12.7 mm) under shear stress up to 4.0 lbs/ft2 (191 Pa).

The ultra-strong structure drives the vegetated shear resistance up to 14 lbs/ft2 (672 Pa), establishing a new maximum for vegetation reinforcement. The P550 TRM may be used as an alternative for poured concrete or articulated concrete blocks in extreme erosion control projects.

VMax® C-TRMs combine three-dimensional matting with fiber matrix material for permanent erosion control on severe slopes, spillways, stream banks, shorelines and in high- to extreme-flow channels. These extensively tested products provide maximum performance through all three phases of reinforced vegetative lining development: un-vegetated, establishment, and maturity. Incorporating the best performance features of temporary and permanent Tensar erosion control products, VMax C-TRMs deliver these tangible benefits:

• Surface-applied for the highest level of immediate soil protection
• Less than one third of the installed cost of rock or concrete
• No heavy equipment needed to install
• More attractive and effective “Green” alternative than rock riprap or concrete
• Exceeds FHWA and ECTC standards for TRMs
• An EPA Best Management Practice (BMP) for National
• Pollutant Discharge Elimination System (NPDES) regulations
• No threat to pedestrians or automobiles when used near travel routes
• Naturally filters runoff water
