Permanent Erosion Control Blankets

A Turf Reinforcement Mat is a permanent erosion control blanket. This type of rolled erosion control product provides long term protection against soil erosion. Turf reinforcement mats are recommended for long term projects, steep slopes and channels that are subject to high stress and high flow.

Types of Turf Reinforcement Mats

We supply a variety of high-performance turf reinforcement mats that are manufactured from different fibers including 100% recycled consumables, coconut fiber and Curlex®. Many permanent erosion control blankets have two nets but American Excelsior’s TriNet® series has three nets.

Recyclex® TRM-V

Recyclex® TRM-V is an American Excelsior turf reinforcement mat manufactured from 100% post-consumer recycled bottles. The permanent erosion control blanket features crimped and curled fibers covered with a heavy duty polypropylene black netting on the top and bottom. 

Recyclex® TRM-V has a specific gravity greater than 1.0 which means it does not float.

Key Metrics

  • Channel flows up to 16 feet/second
  • Withstands shear stress up to 8.0 lb/ft²
  • For 0.5:1 slopes

Recyclex® TRM

Recyclex® TRM is a permanent erosion control blanket made entirely of recycled post-consumables. Recyclex® fibers are curled and crimped to create an interlocked mat that protects against erosion on steep slopes and high velocity channels.

The turf reinforcement mat is covered with an extra heavy duty black netting on the top and a heavy duty polypropylene net on the bottom. Recyclex® TRM fibers have a specific gravity greater than 1.0 so it does not float during heavy hydraulic events.

Key Metrics

  • Channel flows up to 17 feet/second
  • Withstands shear stress up to 10 lb/ft²
  • For 0.5:1 slopes

What’s the difference between Recyclex® and Recyclex® TRM-V?

On the surface, Recyclex® TRM and Recyclex® TRM-V appear identical. Both turf reinforcement mats are made from 100% recycled bottles, are green in color, do not float and are rated for steep slopes.

Recyclex® TRM, however, has an extra heavy duty netting (as opposed to a standard heavy duty netting) on the top. This extra heavy duty netting improves the turf reinforcement mat’s performance properties including tensile strength, specific gravity, and germination improvement.

TriNet® Turf Reinforcement Mats

TriNet® mats are permanent erosion control blankets that provide long term protection in swales, ditches and on steep slopes. While many turf reinforcement mats have two nets, the TriNet® series by American Excelsior has three nettings; two heavy duty nets on the top and bottom plus an ultra heavy duty netting in the middle.

TriNet® Straw/Coconut Blanket

The TriNet® Straw Coconut Turf Reinforcement Mat has a 70% straw 30% coconut matrix in between two layers of heavy duty UV stabilized netting. There is also an ultra heavy duty netting in the middle of the mat. This Straw Coconut Erosion Control Blanket has a permanent service life and offers improved reinforcement between vegetation and the root systems.

TriNet® Coconut Blanket

The 100% Coconut TriNet® Blanket is a permanent coconut blanket for lasting stabilization and vegetation support. The coconut fiber mat is covered on the top and bottom with a heavy duty UV stabilized net. In the middle of the turf reinforcement mat is an ultra heavy duty netting.

TriNet® Curlex® Blanket

This Curlex® Blanket has three nets for ultimate erosion control, permanent service life and improved vegetative establishment. The erosion control mat features American Excelsior’s patented curled and cleaned excelsior fibers, made from Great Lakes aspen wood fibers. There is a heavy duty UV-stabilized net on the top and bottom of the permanent erosion control blanket, and one ultra heavy duty netting in the middle.

TriNet® Recyclex® TRM

The TriNet® Recylcex® Turf Reinforcement Mat is our toughest permanent erosion control blanket. This high performance TRM is made entirely from 100% recycled bottles and includes three nets: two heavy duty nets and one ultra heavy duty net in the middle. If you need permanent erosion control for steep slopes and high velocity channels, choose TriNet® Recyclex as your rolled erosion solution.

TriNet Recyclex Installation Guide
  • Grade and compact soil before installation of TriNet® Turf Reinforcement Mats
  • Remove all debris and obstructions before installation
  • Soil should be seeded, fertilized to soil needs/site specifications prior to installation
  • Roll out the Turf Reinforcement Mat with the roll facing towards the area to be covered
  • The TRM should be flat and smooth
  • Anchor the TriNet® TRM to the ground with Sod Staples

Turf reinforcement mats are typically installed vertically on the slope, however, there are cases in which a horizontal installation is more practical. Always follow the Engineer’s specified requirement for installation. 

If the installation requires more than one width, overlap the TRM edges and secure the TRMs with a row of Sod Staples.

TriNet® TRMs shall be trenched at the head of the slope if the blanket cannot be extended three feet over the slope crest or if an overland flow is anticipated from upslope areas.

Install TRMs in the middle of the channel in the same direction as water flow.

Overlap the additional turf reinforcement mats away from the center of the channel and continue up the channel side slopes three feet above the anticipated high water elevation.

Anchor the TRM with a staggered staple pattern at the end of roll overlaps and at the end of each roll

Flanks exposed to runoff, or sheet flow, must be trenched in.

TriNet TRM shall be trenched at the start of channels.
