Coir Silt Check for Erosion Control

The coir silt check is a natural fiber coir product that has been used in many erosion control and BMP construction applications. Made from 100% Coir Fiber, these silt checks are the perfect way to filter, trap, and control sediment and erosion.

This coir wattle has been frequently used in check dams, around construction site entrances, on slopes and along banks for restoration and protection.

Learn More about the Coir Silt Check

This coir wattle has been used as an effective BMP in various types of construction applications. When considering this wattle, there are several advantages this wattle offers that others do not.

• Natural Coir Netting: This makes the entire wattle biodegradable and safe for the environment. Coir netting is not harmful to wildlife or the environment.

• Easy to Install and Maintain: No maintenance needed as the coir log can be placed quickly. No removal is necessary

• Prevents Upstream and Downstream Erosion: This coir wattle can be manufactured with one upstream and one downstream apron. This prevents downstream and upstream undercutting.

• More Economical and Effective than a Natural Check Dam

By providing coir wholesale pricing, Granite Environmental, Inc. offers a wide variety of natural and synthetic geotextiles. BioD-SiltCheckTM is perfect for sediment erosion control in streams. 100% out of coir fiber and biodegradable, this coir silt check product is manufactured as a coir wattle.

The function of the coir wattle is to reduce the water flow and filter the sediment. The two aprons catch sediment by preventing downstream and upstream undercutting. This helps to retain sediment while still allowing water to flow freely through the unit.
