Coir Silt Check for Erosion Control

Perfect for use in Streams, Channels, Ditches, and Runoff

coir silt check

The Coir Silt Check is a biodegradable product 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 flow in your stream. Along either side of the wattle is a filter apron that helps retain sediment and prevent erosion. Combined, these products are 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. Rather than featuring just a wattle, the silt check enhances control by adding a bottom matting to the stream back 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 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.

Other Coir Product Options

For further erosion control along banks, streams or other erosion-prone areas, we also offer several additional coir products including mats, wattles, blocks, and logs. Depending on your location, required erosion control, and water flow, different products may be able to work better than others. Information on each of these products and their uses can be seen in the links below:
