3D Erosion Control Mats — Biodegradable Geomats

Biodegradable mats — such as straw, wood fiber, and coconut fiber blankets — break down naturally over 3 months to 3 years while vegetation establishes. Permanent mats, like Flexamat or Concrete Canvas, remain in place indefinitely and are designed for high-velocity, high-stress environments such as channels, riverbanks, and culvert outlets where long-term structural protection is required.

For steep slopes, double-netted erosion control blankets are suitable for gradients up to 1:1. Flexamat's high-strength bi-axial polypropylene geogrid with 5000 psi concrete blocks provides permanent protection on severe slopes. The right choice depends on slope gradient, expected flow velocity, vegetation goals, and whether the solution is temporary or permanent.

Many erosion control mats are specifically designed to encourage vegetative growth. Biodegradable blankets provide cover, warmth, and moisture retention to enhance seed germination. Flexamat allows grass to grow through its open concrete block structure and can be mowed once vegetation is established. ScourStop is a vegetated mat offering a natural-looking, permanent alternative to rock riprap.

Yes. Several products in our lineup, including Erosion Control Blankets (Curlex) and ScourStop, are available as NPDES-compliant erosion control solutions. Concrete Canvas also features a low alkaline reserve and low wash rate, minimizing ecological impact. Coleman Moore Company can assist in selecting products that meet your project's regulatory and stormwater permit requirements.

Concrete Canvas is a cement-impregnated fabric that hardens within 24 hours of hydration, forming a rigid protective shell ideal for ditch lining, culvert protection, and shoreline armor. Flexamat uses a bi-axial geogrid with pre-attached concrete blocks and allows vegetation to grow through it, making it better suited for applications requiring both structural protection and a green, maintainable surface.

Selection depends on several factors: project timeline (temporary vs. permanent), slope gradient, expected hydraulic velocity, vegetation requirements, and regulatory compliance needs. Short-term straw blankets suit moderate slopes and revegetation projects, while concrete-based mats like Flexamat or Concrete Canvas are required for high-velocity channels or permanent infrastructure. Coleman Moore Company's team provides product selection assistance tailored to your specific site conditions.
