A biocomposite turf reinforcement mat with seed-free Great Lakes Aspen wood fibers and extra heavy-duty black netting top and bottom — engineered for permanent reinforcement on erosive soils and steep, long slopes.
Free shipping, all orders
Permanent reinforcement, ~36-mo fiber life
Made in the USA
Curlex Enforcer, is biocomposite turf reinforcement mat. One of many different erosion control matting options available. It contains seed free Great Lakes Aspen wood fibers. The top and bottom of each blanket is covered with extra heavy-duty black netting. The fibers are designed to provide approximately 36 months of service life, but the remaining TRM components are permanent.

Step 1 of 3
Why Enforcer
Built for Erosive Soils & Steep, Long Slopes
Permanent reinforcement
A biocomposite TRM: the Aspen fibers give roughly 36 months of service life while the remaining components stay permanent.
Heavy-duty netting
Extra heavy-duty black netting covers the top and bottom of every mat for durability on demanding sites.
Seed-free Aspen fibers
Seed-free Great Lakes Aspen wood fibers create a surface cover that reduces erosion and helps vegetation establish.
Steep-slope ready
Engineered for far-from-ideal conditions — erosive soils and steep, long slopes where blankets alone fall short.
Curlex Enforcer in Action
Case Study
Curlex Enforcer for Keeping Soil in Place
Sioux City, Iowa
Protecting 100-ft cut slopes above a new store & parking lot
Erosive native loess soils and steep, long slopes called for more than a standard blanket. Good planning, a strong design, and Curlex Enforcer QuickGrass delivered a permanent erosion-control and revegetation solution.
Location

The Team
A diversified project team came together across several states with one goal — a successful erosion-control and revegetation project.
- Jered Morris, Olsson and Associates (Lincoln, NE) — project engineer
- Colorado Structures (Colorado Springs, CO) — primary contractor
- K & L Construction (Bluff, Iowa) — excavation sub-contractor

The Plan
NPDES Phase II requires sites of one acre or larger to follow the correct permitting process, and a Storm Water Pollution Prevention Plan (SWPPP) had to be created before the land could be disturbed. With permits approved, excavation and stabilization of the cut slopes began in the fall of 2002.
To address concerns about the long slope lengths, Morris broke up the slope with benches: three paved and guttered benches were built at right angles to the slope to collect and redirect stormwater runoff, with a fourth gutter system across the base to protect the parking lot below.

Choosing the Product
After evaluating site conditions with American Excelsior Company (AEC), the team selected Curlex® Enforcer® QuickGrass® — dyed-green excelsior wood fibers with heavy-duty UV-stabilized polypropylene netting. It was chosen because:
- Foreseen hydraulic forces wouldn’t require the original product’s performance degree
- The biodegradable wood-fiber element improves vegetation establishment over long-term matrices
- Lower material cost with equal or better results
- Green color gives a finished look until vegetation establishes
- Offers permanent reinforcement for vegetation

Installation
Six inches of topsoil was spread across the graded slopes to resist the erosive native loess soils, then all disturbed land was seeded with native grass and wildflowers, with oats added as a quick cover. An eight-man crew worked from the top of the slope down to the base, installing almost 50,000 yds of composite TRM.

Nature’s Bump in the Road
Shortly after install, the system withstood two heavy storms (~3 inches of rain, then two more). A third storm dropped nearly four inches while the bench storm drains were still covered for ongoing excavation — water over-topped a bench and channeled into an erosion river.
When the storm passed, only a small section of the 50,000-yard project was affected — an area roughly 24 ft × 20 ft needed repair. The team credited the slope design for how well the system held up.
A Successful Conclusion
To date, the system benches and composite TRMs are an aesthetic, successful erosion-control solution. The store and parking lot below the slope are permanently protected — thanks to a project team that devised and executed the right erosion and sediment control plan.

Questions
Frequently Asked Questions
Where is this product made?
They are all made in the USA.
Are these blankets biodegradable?
The fibers are fully biodegradable with a service life of approximately 36 months, but the remaining components of the product are permanent.
What are the fibers made from?
They are made from renewable Great Lakes aspen that are provided by members of sustainable forestry programs.
How long will shipping take?
All orders ship for free. Orders typically ship out within 1-2 business days if placed before 1PM Eastern; approximate transit times are 2-4 business days.
Are these blankets already seeded?
No, they are not. As different parts of the country should use different types of seeds. All of our blankets come seed free.
Can I purchase less than the 15 mat minimum?
Unfortunately no, we can only sell at least a pallet or more which is 15+ mats.
