Erosion Control Wattles
Sedimentation Control and Installation
Erosion control wattles are effective BMPs for locations where filtration, sedimentation control, or silt containment is a requirement. Often used to create a filtered water flow from your site, coir wattles help to retain sediment, dirt, and debris from water as it flows through the barriers. Wattles are available in diameters of 6 or 9 inches to accommodate the needs of your area.

Coir Wattle Installation
The installation of coir wattles is very similar to that of coir logs. Both sediment control products generally use stakes, either wooden or Biodegradable, in their placement and installation processes. The stakes can be placed either along the sides of the wattle or directly through the middle to keep it in place. Staples can also be used along the bottom of the erosion control wattles to stabilize their placement. Of course, these methods of wattle installation rely on soil, sediment, or dirt surfaces.
When coir wattles are placed around street drains and inlets, an alternative installation method is needed since stakes or staples can't be used with concrete or pavement. Sandbags, gravel bags, or other weighted materials are necessary to keep the wattles in place and to ensure effective sedimentation control.
GEI Works also offers erosion control wattles made with materials other than coir. Straw erosion wattles are available in 9", 12", and 20" diameters to meet the requirements of different locations. For more information, view our Straw Erosion Control Wattles.
