Erosion Barrier, Anti-Erosion Mat & Erosion Mesh: Complete Guide
Erosion Barrier, Anti-Erosion Mat, and Erosion Mesh Guide
Decoding the terminology — what these products are, how they differ, and which is right for your site
Erosion Barrier Terminology: Decoded
The erosion control product market uses many overlapping terms. Whether you are searching for an “erosion barrier,” “anti-erosion mat,” “erosion mesh,” or “soil erosion blanket,” you are most likely looking for the same family of products — erosion control blankets (ECBs). Here is how the terms map:
Erosion barrier — Broad term for any product or structure that prevents erosion. In surface erosion control, usually refers to an ECB or mat placed on soil. Can also refer to structural measures like silt fences.
Anti-erosion mat — A rolled mat placed on bare soil to prevent erosion by rain and runoff. Synonymous with ECB. Natural fiber options are biodegradable; synthetic options (TRMs) are permanent.
Anti-erosion mesh — The netting system in an ECB, or a standalone netting product used to hold mulch or organic material on slopes. The mesh provides the mechanical anchoring that keeps loose fiber in place.
Erosion control mesh — Interchangeable with anti-erosion mesh. Also used to describe photodegradable or biodegradable netting applied over seeds and loose soil cover on slopes.
Soil erosion blanket — An ECB — a rolled mat of natural or synthetic fiber used to protect topsoil from rain and runoff. The “blanket” describes how it covers and protects the soil surface.
Turf reinforcement mat (TRM) — A permanent synthetic mat that reinforces established turf in high-shear channel applications. Not temporary; not biodegradable. Used where flow velocities exceed ECB capacity.
Erosion Control Blankets (ECBs) — The Core Product
When buyers search for erosion barriers, anti-erosion mats, or soil erosion blankets, they are almost always looking for erosion control blankets. An ECB is a rolled product consisting of:
- A layer of natural or synthetic fiber (wood excelsior, straw, coconut coir, or polypropylene)
- One or two netting layers stitched through the fiber to hold it in place
- A consistent, machine-made structure that ensures even coverage and predictable performance
ECBs are installed directly on bare, seeded soil and staked in place. They protect topsoil from raindrop splash and runoff, retain soil moisture for seed germination, and decompose after vegetation is established (biodegradable types) or remain permanently (TRMs).
The Curlex product line — manufactured by American Excelsior Company using Great Lakes Aspen wood fiber — is among the highest-performing ECB products available. The crimped fiber structure provides exceptional soil coverage, moisture retention, and slope stability.
Anti-Erosion Mat Types
| Mat Type | Material | Biodegradable? | Best Application |
|---|---|---|---|
| Wood fiber ECB (single-net) | Great Lakes Aspen excelsior | Yes (fiber + photodegradable net) | Slopes up to 2:1, moderate channels |
| Wood fiber ECB (double-net) | Great Lakes Aspen excelsior | Yes (fiber + photodegradable net) | Steep slopes up to 1.5:1, aggressive channels |
| Wood fiber ECB (triple-net) | Great Lakes Aspen excelsior | Yes (fiber + photodegradable net) | Steep slopes up to 1:1 (1H:1V) |
| 100% biodegradable ECB | Wood fiber + bio netting (or net-free) | 100% natural decomposition | Sensitive sites, riparian, wildlife areas |
| Straw ECB | Agricultural straw | Yes (fiber + net varies) | Gentle slopes, low-cost stabilization |
| Coconut coir ECB | Coconut husk fiber | Yes (longer design life) | Wet sites, riparian, slow-establishing veg |
| Turf reinforcement mat (TRM) | Synthetic polypropylene | No — permanent | High-velocity channels, permanent steep slopes |
Erosion Control Mesh and Netting
Erosion control mesh refers to two distinct applications:
Mesh as Part of an ECB
All standard ECBs use a netting (mesh) system to hold the fiber fill in place. Without the mesh, the fiber would migrate downhill in the first rain event. The mesh is typically polypropylene (photodegradable) or, in fully biodegradable products like Curlex I Fibrenet, made from biodegradable jute netting. (For sites where no netting is wanted at all, Curlex NetFree removes the mesh entirely.) The mesh is the component that makes a netted ECB a true “erosion barrier” rather than just scattered mulch.
Standalone Erosion Mesh
Standalone erosion mesh — sold without fiber fill — is used to:
- Hold loose straw or compost on gentle slopes after application
- Anchor seed to a slope face before vegetation establishes
- Provide temporary slope cover in low-risk, low-slope applications
Standalone erosion mesh provides less protection than a full ECB because it relies on the loose material beneath it for soil protection — it does not provide the dense, uniform coverage of a fiber-filled ECB.
Soil Erosion Blanket Guide
A soil erosion blanket is placed on bare soil to protect the topsoil during the period before vegetation is established. Key performance attributes to look for:
- Percent soil coverage: Higher is better. Wood fiber ECBs provide near-complete soil coverage; jute mesh and loose mulch provide partial coverage.
- Moisture retention: The blanket should retain soil moisture at the surface to support seed germination and seedling establishment. Dense wood fiber is superior to open-weave materials for moisture retention.
- Slope rating: Products are tested and rated for maximum slope gradient and channel flow velocity. Match the product rating to your site conditions.
- Design life: The blanket must remain functional through the vegetation establishment period. Match design life to the expected establishment timeline for your seed mix.
- Netting type: Photodegradable polypropylene netting is standard. For sensitive sites, specify fully biodegradable netting (Curlex I Fibrenet) or a net-free blanket (Curlex NetFree).
How to Choose the Right Product
Use this decision guide:
- Slope up to 2:1 (2H:1V) and flatter, typical construction or landscape use: Curlex I (single-net wood fiber ECB)
- Steeper slope up to 1.5:1 (1.5H:1V) and flatter: Curlex II (double-net wood fiber ECB)
- Steeper ground up to 1:1 (1H:1V): Curlex III (triple-net wood fiber ECB — the steepest-slope Curlex blanket)
- Net-sensitive or wildlife-/mowing-sensitive site: Curlex NetFree (netting removed entirely)
- 100% biodegradable netting required: Curlex I Fibrenet (biodegradable jute netting — note: custom-made, with a 270-roll / half-truckload minimum order)
- Narrow ditch, channel, or tight-access area: Curlex I 4-foot roll
- High-velocity channel (over 6 ft/s) or permanent steep slope: Turf reinforcement mat (TRM) — contact Eastgate Supply for specifications
Installation Basics
These steps follow the manufacturer's Curlex Installation Guidelines. Always confirm the staple pattern and spacing on the product's spec sheet, since they vary by product and slope.
- Prepare the seedbed: fine-grade and compact the soil, remove existing rills, and clear stones, roots, and debris.
- Seed and fertilize before the blanket goes down — Curlex blankets are not pre-seeded.
- Roll the blanket out flat, even, and smooth without stretching it, keeping full contact with the soil.
- On slopes: install the blanket vertically (down the slope). Where more than one width is needed, abut the edges together and secure them with a common row of staples — side overlaps are not required on slopes. Trench in the top edge if the blanket can't extend three feet over the slope crest, or if overland flow is expected from above.
- In channels: center the blanket so the seam is off the middle of the waterway, install in the direction of flow, overlap adjoining blankets away from the center, and carry the blanket about three feet above the anticipated high-water line. Trench the upstream start and protect exposed flanks with a check slot or trench. Use a staggered staple pattern at overlaps and roll-end terminations.
- Staple/anchor per the product's staple-pattern spec, with denser anchoring at edges, seams, and transitions.
- Curlex requires no watering to function, but irrigating after installation can help initiate seed germination and confirm soil contact.

Erosion Control Product Finder →Frequently Asked Questions
What is an erosion barrier?
An erosion barrier is any product or structure installed to prevent or slow soil erosion. The term includes both surface-applied products (ECBs, anti-erosion mats, erosion mesh) and structural measures (silt fences, sediment barriers, check dams). In surface erosion control, an erosion barrier typically refers to a rolled mat or blanket placed on bare soil.
What is an anti-erosion mat?
An anti-erosion mat is a surface-applied erosion control product — typically a rolled mat made from natural or synthetic fiber — placed on bare soil to protect against rain impact and runoff. Anti-erosion mats include ECBs (erosion control blankets), turf reinforcement mats (TRMs), and coconut coir mats. They are installed by staking directly to sloped or disturbed soil.
What is erosion control mesh?
Erosion control mesh refers to the netting component of an ECB, or to lightweight mesh products (like jute or synthetic netting) used to hold loose organic material (mulch, compost, straw) on slopes. The mesh prevents the material from washing downhill during rain events.
What is a soil erosion blanket?
A soil erosion blanket is another name for an erosion control blanket (ECB) — a rolled mat of natural or synthetic fiber placed over bare soil to protect topsoil from rain impact and runoff. Soil erosion blankets are staked over seeded areas and decompose naturally after vegetation is established.
How are ECBs different from silt fences as erosion barriers?
ECBs are surface erosion control products applied directly to bare soil to prevent soil detachment at the source. Silt fences are perimeter sediment barriers that capture sediment already in suspension. ECBs prevent erosion; silt fences filter runoff. Both may be required on a construction site under SWPPP regulations.
What is the best anti-erosion product for a slope?
For most slope applications, a wood fiber erosion control blanket (ECB) like Curlex I or Curlex II is the best anti-erosion product. It provides complete soil coverage, excellent moisture retention for seed germination, and mechanical anchoring via the netting system. Choose Curlex I for slopes up to 2:1 (2H:1V) and flatter, and Curlex II for steeper ground up to 1.5:1 (1.5H:1V) and flatter. For ground steeper than Curlex II's range, step up to Curlex III, which is rated to 1:1 (1H:1V).
