Turf Reinforcement Mats

Designed for slopes requiring permanent reinforcement, turf reinforcement mats provide all the benefits of an erosion control blanket (ECB) and then permanently anchor root systems to the surface soil. They're the most efficient way to provide permanent erosion control on moderate to extreme slopes, low to high-flow channels and many applications in between. The stability that TRMs provide allows root systems to establish solid ground support.


Flexamat consists of concrete shapes, locked together with a high strength, polypropylene geogrid. There are openings around each concrete block that give Flexamat the flexibility and enable it to be packaged in rolls. The openings also allow vegetation to grow through the mat. Eventually, vegetation will completely cover Flexamat. It can be manufactured with various backings such as non-woven fabric to stop vegetation growth or a TRM (turf re-enforcement mat) depending on the soil conditions and other factors.
