Erosion Matting for Slopes

Coir Mats For Slopes and Hills

erosion control mat on a slopeQuestion: I was interested in some erosion matting for slopes and I had some additional questions. Where can I find information on the shear strength or erosive velocities of these products? Do you know if there is a such as thing as a permanent mat or do they all biodegrade? I have a slope that will be experiencing some concentrated flows, but not to the point where I want to line it with rip rap. The flow is probably pushing 5 fps. What do you recommend?

Answer: In terms of strength, we do offer natural fibers that can be used for the type of slope and flow that you have described. The most common natural fiber that is used for strength is one of our Coir Mats. These mats have a typical lifespan of around four to six years (4 - 6 yrs.).

This is long enough to provide extensive erosion control for customers looking to naturally stabilize their area. Typical water flows where these erosion control mats have been used include:

  • Coir Mat 40: Used for flows up to 8 fps.
  • Coir Mat 70: Used for flows up to 12 fps.
  • Coir Mat 90: Used for flows up to 16 fps.
  • Coir Mat 100: Used for flows up to 17 fps.

If you have questions about any products give us a call at +1-772-646-0597 or request a price quote.

As seen in the listing above, even the lowest coir mat is equipped to handle a flow up to 8 fps. This should be able to support your slope even with the flow you have described.

In addition to flow, another factor you could consider to help choose your erosion control material is the steepness of your slope. Coir and straw mats are usually equipped to handle slopes that are either 1:1, 2:1, 3:1 or lower. Straw mats will be used on some of the flatter slopes, while our strongest coir materials can be used on the steepest slopes.

Finding Erosion Control Specifications

Regardless of which product you choose, each individual page should feature a specification at the bottom of the page that allows you to see the weight and strength of each material. Charts should additionally show the lifespan of each mat or blanket.

Additional Options

woven geotextilesIn addition to this biodegradable erosion matting for slopes, we do also have synthetic geotextiles that can be used for erosion control and stabilization applications. These Geotextiles are typically made from a polypropylene material that will not biodegrade over time. This can offer you a long term or even permanent erosion control option. Common synthetic products have included the following:

  • Woven Geotextiles
  • Nonwoven Geotextiles
  • Turf Reinforcement Mats (TRMs)
  • Polypropylene Mats and Blankets
