Erosion Control Wetland Restoration

Restore Ecosystems with Erosion Control Blankets

erosion control matQuestion: I am in need of erosion control wetland restoration materials. I think I will require several erosion control mats, but I'm unsure of how to determine which one will work best in my location?

Answer: Due to the natural environment that typically surrounds a wetland area, the most common erosion control option is a product that is made from a natural material such as coconut coir. Unlike other fabric materials, these coir products will naturally biodegrade over a period of time, leaving the surrounding soils enriched.

Choosing this type of erosion control material can provide you with a stabilized erosion control area that will not bring additional harm to the surrounding environment. Located on the Wetland Restoration page you will find several erosion control materials that are frequently used during wetland restoration projects.

The Coir Erosion Control Mat

erosion and sediment control matOne of the most common products used in erosion control wetland restoration is an coir erosion control mat or blanket. These coir materials are made using a combination of mattress coir and coir twine.

Mattress coir is placed within the coir twine netting which has been weaved in different intervals. Typically, the larger the weave opening is on your mat, the lower the strength of the mat.

All coir materials are derived from the husks of coconuts. These shavings are taken and soaked in water for extended periods of time to increase the strength of the coir. This means that any coir product will provide extended strength and will typically last anywhere from four to six years (4-6 yrs).

Coir Matting Options

Coir mats are typically made from the same materials, but will vary based on their packing density, the size of the weave openings, and the weight. The following can be used as a general guide to some of the differences you may find in these mats:

  • Coir Mat 40: Weight of 400 g/sq. m
    • Lighter Strength Mat
    • Recommended Flow of 8 fps
    • Open Area of 65%
    • Recommended Slope of 3:1

  • Coir Mat 70: Weight of 700 g/sq. m
    • Medium Strength Erosion Control
    • Recommended Flow of 12 fps
    • Open Area of 50%
    • Recommended Slopes of 2:1 or 1:1

  • Coir Mat 90: Weight of 900 g/sq. m
    • High Strength Mat
    • Recommended Flow of 16 fps
    • Open Area of 39%
    • Recommended Slope of 1:1

  • Coir Mat 100: Weight of 1,017 g/sq. m
    • Highest Strength Erosion Control
    • Recommended Flow of 17 fps
    • Open Area of 36%
    • Recommended Slope of 1:1

Also available for Wetland Restoration are several other coir materials including a liner pad and coir bed.
