Straw Wattle 9 in. x 25 ft.

Fiber rolls (or straw wattles) are very effective for sediment control. They reduce the rate of water flow, simultaneously absorbing water and filtering sediment. When used for temporary sediment retention, fiber rolls can reduce off-site sedimentation by providing storm drain inlet protection, directing runoff water to retention and detention devices, reducing water velocities in areas of concentrated flow, such as waterways and swales, when installed as check structures, and functioning as an alternative to silt fence for perimeter sediment control.
