Coir Silt Check for Erosion Control

Perfect for Use in Streams, Channels, and Ditches

coir silt checkThe Coir Silt Checks available from GEI Works are a biodegradable erosion control solution designed for use as a check dam in streams, channels, drainage ditches, and other site runoff areas. Constructed from 100% coir fiber, these wattles are an all natural way to filter stormwater and control sediment in your water streams.

Silt checks are designed as a combination of both a coir mat and a coir wattle. Along the center of the device is a wattle that works to reduce water flows in streams. Along either side of the wattle is a filter apron that helps retain sediment and prevent erosion. Combined, the coir silt check is able to filter water, reduce flows, and control bed erosion around job sites, ditches, and other drainage areas.

How the Silt Check Works

coir silt check for large body of waterThe Coir Silt Check is essentially a combination of a coir mat and a coir wattle, acting as a check dam. Rather than featuring just a wattle, the silt check enhances erosion control by adding a bottom matting to the stream bank or water area. Advantages include:

Side Aprons Prevent Upstream and Downstream Erosion: The coir silt check is manufactured with one upstream and one downstream apron. Upstream aprons help to prevent undercutting, while downstream aprons work to retain silt and prevent erosion.

Natural Coir Netting: Natural coir netting makes the entire wattle a completely biodegradable product. This keeps the materials environmentally friendly and prevents harm to wildlife or other environmental areas.

Easy to Install and Maintain: As with any of our coir products, the silt check dam is designed for one time installation. Over time, wattles will biodegrade. With no removal necessary, this makes the wattle quick to install and easy to maintain over a period of time.
