Turf Reinforcement Mats (TRM)

The ideal erosion control solution for slopes and in channels where enhancing and anchoring vegetation is the goal.

Turf Reinforcement Mats (TRM) are the ideal product for long term erosion protection on slopes and in channels. They are used in applications where two to three times the normal erosion protection is necessary. Made of flexible, three dimensional polypropylene, TRMs can mold to the vulnerable area and are anchored to the soil to promote the growth of vegetation. Use TRMs for a permanent solution for erosion control while allowing for mature plant growth.

TRMs are the preferred environmental alternative to hard armor. Applications include protection in drainage ditches, open channels, steep slopes and detention basins.

  • Manipulate the Turf Reinforcement Mat to the environment
  • Provides a permanent solution anchoring vegetation and promoting mature growth
  • Resilient against high stress, UV and high velocity water
  • ASTM Tested, please refer to the chart for complete details
