The erosion wattle (also known as coir wattle) provides a practical and economical alternative for government, landscaping, or construction projects needing to keep stormwater clear of sediment and debris. Not only do they act as an efficient form of sediment control, but since they are made from fiber harvested from coconuts, these coir products are also fully biodegradable and environmentally friendly. As an all-natural alternative for sediment control and stormwater filtration, coir fiber wattle can be left long term on a site without worry over potential environmental damage resulting.
Coir fiber wattle is a recognized stormwater BMP and when applied properly is an affordable way to satisfy federal stormwater regulations. The coir fiber wattle is a practical sediment control solution for limited project budgets. It is used for preventative erosion control because of its ability to direct groundwater flow while effectively filtering out sediment. For applications where there may be pollutants other than just sediment in the runoff, you can keep the site compliant by pairing coir wattle with the use of absorbents or other treatments. Coir fiber wattles for sediment control applications typically remain effective for up to 24 months in the field, depending on water flow. Coir is relatively waterproof and is resistant to saltwater damage. Submersion does not cause quick degradation. For a 100% green BMP solution, use biodegradable stakes to anchor the coir wattle.
Advantages to using coir erosion wattle:
- Safe for the environment
- Fast and easy installation
- No removal or disposal costs
- Low maintenance
- Easy to move
Note: While coir logs look very similar to coir erosion wattle, they have a very different purpose. Coir logs are much more densely packed and are primarily used for soil stabilization, including along higher flow stream banks or hillsides. With the coir erosion wattle, sediment control and filtration are the goals, and the coir fiber is instead loosely packed to allow water to filter through.
