Rolled Erosion Control Products & Systems

Longevity depends on the fiber type. Single-net straw blankets last approximately 3 months, wood fiber blankets last 12 to 24 months, and double-netted coconut fiber blankets provide 2 to 3 years of coverage. For permanent solutions, Flexamat and Concrete Canvas offer indefinite service life once installed and anchored.

For steep slopes, double-netted blankets are rated for up to 1:1 slope gradients, while Flexamat — with its bi-axial polypropylene geogrid and 5000 psi concrete blocks — provides permanent hard armor on severe embankments. Product selection should account for slope ratio, soil type, vegetative goals, and expected hydraulic conditions.

Yes. Concrete Canvas is specifically engineered for installation in rainy conditions, which eliminates weather-related project downtime. The cement-impregnated fabric cures with water in approximately 24 hours, making it highly practical for channel linings, culvert invert protection, and slope stabilization where site conditions are unpredictable.

Yes. Products like Flexamat are designed to allow vegetation to grow up through the mat after installation, and once grass is established, the mat can even be mowed. ScourStop is also a vegetated system that provides a green, natural appearance while delivering the scour resistance of hard armor, making both products ideal where aesthetics matter.

A geotextile filter fabric is typically installed beneath riprap to prevent soil migration while allowing water to pass through. However, products like Flexamat and ScourStop can replace riprap entirely — eliminating the need for a separate fabric layer. ScourStop in particular is a vegetated mat engineered for permanent scour protection that outperforms traditional rock riprap in longevity and aesthetics.

Yes. Erosion Control Blankets from American Excelsior Company and ScourStop by Landmark are confirmed NPDES-compliant products. Concrete Canvas also features a low alkaline reserve and low wash rate, resulting in minimal ecological impact. Coleman Moore Company can help you select the appropriate NPDES-compliant solution for your permitted project site.

Rolled erosion control products are used across a wide range of applications, including highway embankments, bridge abutments, and roadside channels for civil and transportation infrastructure; detention basins, curb inlets, and letdown channels for stormwater and municipal projects; stream banks, river channels, and shorelines for waterway restoration; and freshly graded construction sites and embankments for site development. Coleman Moore Company has been serving Iowa contractors, engineers, municipalities, and developers across hundreds of civil projects since 2004.
