Straw Wattles
Coir Wattle Erosion Control
Straw wattles and erosion control wattles provide a biodegradable, cost-effective way to control sediment and manage stormwater runoff on active sites. Often used as coir wattles or fiber rolls, they slow flow, break up slope length, and help keep disturbed soil in place on construction sites, roadway embankments, hillsides, drainage channels, and restoration areas.
These BMP-compliant erosion control wattles slow runoff, trap sediment, and promote vegetation growth. Available in common 6- and 9-inch diameters, they integrate easily into details for perimeter control, slope interruption, check dams, and inlet protection around storm drains and curb inlets.

Erosion Control Wattles Product Details
Because the erosion control wattle is made from all natural coconut coir fibers, it is reusable and completely biodegradable. Coir wattles are a better choice for the environment then synthetic wattles. They also will last much longer, making them budget-friendly. Coconut coir fiber wattles are practical and durable and can be used in a wide range of situations. The inner core is double cleaned unsorted coir fiber surrounded by a coir twine netting with knotted junctions. It designed to filter water while creating a barrier that will effectively reinforce your site.

Erosion Control Wattle Applications
Erosion Control Wattles have a wide range of uses and applications and are perfect for check dams, embankments, storm drains, and construction BMPs. Contractors, DOT and municipal crews, and site inspectors use erosion wattles on construction sites to help keep sediment from leaving active work areas with moving equipment and other construction activities. They are designed to filter materials from stormwater runoff before it leaves the site.
Common applications include:
- Check dams and temporary flow control along channels and swales
- Embankments, hillsides, and slope interruption for erosion control
- Perimeter control around active construction areas and BMP compliance
- Storm drains, curb inlets, and outfalls for sediment filtration
- Restoration areas where vegetation will grow through the wattle over time
Coconut coir wattles can also be used to create check dams. Vegetation can grow through the erosion wattle over time, providing long-term erosion and stormwater control even after the coir erosion wattle has decomposed.
Erosion control wattles filter water as it flows through the wattle. This makes the coir wattle perfect to place in front of curb inlets or storm drains to protect the water supply system.

Erosion Control Wattles Frequently Asked Questions
Coir wattles and coir logs are very similar in design and shape. One of the main differences is that a wattle has a smaller diameter, usually 6 to 9 inches, while the coir log has diameter sizes up to 20 inches. Coir fiber wattles are not as densely packed and are therefore more flexible and easily manipulated. Coir wattles are best used when the situation calls for an erosion control product that is flexible, durable, and lightweight.
Coir wattles are typically installed by digging a small trench and then placing the erosion control wattle into position. Stakes are best positioned every 4 feet on center. For more information on coir wattle installation, see our coir erosion wattle installation page.
