Straw, Coconut and Curlex Erosion Control Blankets
Erosion control blankets provide vegetative support and prevent soil and seed from washing away. Blankets can be installed on slopes, pond embankments, stream restoration projects, channels and anywhere you are experiencing soil erosion.
Temporary Erosion Control Blankets | Short Term
Temporary Erosion Control Blankets are rolled erosion control products composed of natural fibers that are both photodegradable and biodegradable. Straw, Curlex® and jute netting all used to manufacture Temporary Erosion Control Blankets (ECBs). These rolled erosion blankets can last up to 36 months depending on material, application and installation.
Each material has unique qualities that determine the erosion blanket’s cost, degradability and ability to withstand erosion. Install temporary erosion blankets slopes with on 4:1 to 2:1 grade and low velocity channels.
Long Term Erosion Control Blankets
Choose Long Term Erosion Blankets for lasting erosion control and areas that need greater protection against wind and rain erosion. Although these blankets have strength and longevity, they are not classified as permanent turf reinforcement mats. Long term erosion control matting includes Straw/Coconut Coconut Blankets, and double net Curlex® blankets.
Straw mat is the most common erosion control blanket. These erosion blankets are best suited for flat to mild slopes and mild erosion. Straw mat creates a stable network for seed to grow through. As the seedling grows through the straw blanket, it interlocks with the netting and stabilizes the soil.
Straw blankets are manufactured with one (single) or two (double) nets which can be photodegradable or biodegradable.
Single Net Straw Blanket
Single Net Straw Blanket is a temporary erosion control blanket for mild slopes and moderate erosion problems. This rolled erosion control product features a straw mix bonded to one photodegradable net.
A Single Net Straw Erosion Blanket can last up to 12 months when properly installed on mild slopes up to 3:1 and channel flows up to 4.5 feet/second.
All Natural Single Net Straw Blanket
All Natural Single Net Straw Blanket features a straw mat bonded to a 100% biodegradable netting.
Just like standard Single Net Straw Blanket, the All Natural alternative can last up to 12 months when properly installed on mild slopes up to 3:1 and channel flows up to 4.5 feet/second.
Double Net Straw Erosion Blanket
Double Net Straw Blanket is a temporary erosion control blanket for mild to moderate slopes. This straw mat features a straw mix sewn in between two photodegradable nets.
When properly installed, Double Net Straw Blanket can last up to 12 months on 2:1 slopes and channel flows up to 7.0 feet/second.
All Natural Double Net Straw Blanket
The All Natural Double Net Straw Blanket has 100% biodegradable netting. This straw mat features a straw mix sewn in between two biodegradable nets.
When properly installed, Double Net Straw Blanket can last up to 12 months on 2:1 slopes and channels up to 7.0 feet/second.
Straw/Coconut Erosion Blankets incorporate a mixture of straw and coconut fibers. This rolled erosion control product is available with a photodegradable or 100% biodegradable net (all natural). Although Straw Blankets are intended for short term applications, the Straw/Coconut Blanket is classified as a long-term erosion control blanket, due to the strong coconut fiber that extends the mat’s service life.
A Straw/Coconut Erosion Control Blanket features a 70% straw – 30% coconut fiber mat, bonded to a photodegradable net. The coconut fibers strengthen the rolled erosion control product, increasing its longevity.
Straw/Coconut Blanket is suitable for slopes up to 1.5:1 and channel flow ups to 8.5 feet/second. When properly installed, a Straw Coconut Blanket can last up to 24 months.
All Natural Straw/Coconut Blanket
The All Natural Straw/Coconut Erosion Control Blanket has a 70% straw – 30% coconut fiber mat, bonded to 100% biodegradable netting. The coconut fibers strengthen the rolled erosion control product, increasing its longevity.
Straw/Coconut Blanket is suitable for slopes up to 1.5:1 and channel flow ups to 8.5 feet/second. When properly installed, a Straw Coconut blanket can last up to 24 months.
Coconut Erosion Control Blanket
Coconut Erosion Control Blankets are made from exceptionally strong coconut fibers. Coconut fibers are much stronger than straw and excelsior fiber which is why Coconut Erosion Blankets are rated for steeper slopes and higher channel flow.
All coconut fiber mats have two nets; standard mats have polypropylene nets and all natural blankets use 100% biodegradable netting.
100% Coconut Blanket
This Coconut Erosion Blanket features a coconut fiber mat, stitched in between two polypropylene nets. This exceptionally strong rolled erosion control product can last up to 36 months when properly installed. The 100% Coconut Blanket is rated for 1:1 slopes and channel flow up to 9.0 feet/second.
All Natural Coconut Blanket
The All Natural Coconut Erosion Control Blanket is made from strong coconut fibers. A coconut fiber mat is sewn in between two 100% biodegradable nets. When properly installed, this biodegradable erosion blanket can last up to 36 months. All Natural Coconut Blanket is rated for 1:1 slopes and channel flow up to 9.0 feet/second.
Curlex® Erosion Control Blankets
Curlex® Erosion Control Blankets are American Excelsior’s patented excelsior rolled erosion control products. The Curlex® fibers are made from renewable Great Lakes aspen wood fibers. Each fiber is cleaned, curled and six inches or greater in length.
There are many different Curlex® blankets to choose from including options with photodegradable or biodegradable netting. Curlex® erosion blankets are offered with zero, one, two or three nets.
Curlex® I Erosion Control Blanket features a Curlex® (excelsior fiber) matting attached to one degradable netting. The single net Curlex® Erosion Blanket is suited for slopes up to 2:1 and is rated for channel up to 7.0 feet/second.
Curlex® I Natural
Curlex® I All Natural (FibreNet™) Erosion Blanket consists of Curlex® fibers attached to a 100% biodegradable netting. The All Natural Curlex® Erosion Blanket is rated for slopes up to 2:1 and for channel flow up to 7.0 feet/second.
Curlex® II Erosion Control Blanket consists of a exelsior fiber matting in between two degradable polypropylene nets. The double net Curlex® Erosion Blanket is suited for slopes up to 1.5:1 and is rated for channel up to 9.0 feet/second.
Curlex® II Natural

Curlex® Net Free™
Biodegradable stitching holds this net free Curlex® Erosion Control Blanket together. This biodegradable erosion blanket is ideal maintenance areas on lawns and landscapes because it won’t tangle in lawn mowers or equipment. As the seedling grows through the Curlex® matting, the excelsior fibers and root system interlock to create a stable soil system. Curlex® Net Free™ is suitable for grades up to 3:1.
Although “jute mat” is used to identify all sorts of erosion control blankets, this category of temporary erosion blankets is truly made from jute fiber. Jute is a rope-like fiber that is strong, lightweight and 100% biodegradable. Jute mats have a more open weave compared to the other rolled erosion control products.
Eco-Jute is a 100% biodegradable jute mat. This lightweight mat is ideal for mild erosion problems, specifically in sandy or clay soil. Eco-Jute can be installed on slopes up to 3:1 and applications that require less than one year of control.
Anti-Wash Jute is another type of jute mat that is also known as GeoJute®. This mat is slightly stronger than Eco-Jute and can last up to 1-2 years when properly installed. Anti-Wash Jute is rated for slopes up to 2:1.
Coir mats are made of exceptionally strong coconut fibers. These fibers are twisted and knotted to create a coir mat. Coir matting is all natural and 100% biodegradable. These blankets are ideal for stream restoration projects and other environmental construction projects that require a strong but natural erosion control product – free of polypropylene and netting.
Coir 400 is made from strong and clean coconut fiber. This type of coir matting is rated for slopes less than 1:1 and is estimated to have a functional longevity of 4-6 years.
Coir 700 is a strong coir matting made from coconut twine derived from coconut fiber. This mat has a functional longevity of 3-5 years and is recommended for slopes greater than 1:1.
Coir 900 is a coir mat made from coconut twine derived from coconut fiber. This strong coir mating has a functional longevity of 3-5 years and is recommended for slopes greater than 1:1.
Coir 1000 features two layers of jute matting; an outer coir layer and an inner lightweight jute layer. These two layers are tied together to create an exceptionally strong coir mat that is ideal for stream restorations and coastal protection projects.
