CONTROL OUTLET FOR USE IN CRITICAL SPOTS WITH TROUBLE CONDITIONS WHERE SILT FENCES FAIL

CRAFS is a corrugated retention and filtration system for sediment control in critical spots where there is a heavy concentration of runoff. This includes areas where runoff accumulates and can overflow, knock down, scour beneath or wash away standard silt fences.

Unlike a traditional sediment retention device (SRD), CRAFS’ corrugated design strengthens the device to reduce the chance of failure and offers a greater amount of fabric surface area to provide rapid filtered seepage through the system. When installed with silt fence, CRAFS provides a “control outlet” to prevent sediment contamination of adjacent properties and waterways.

Series™

- Corrugated design strengthens device and reduces chance of failure

- Provides rapid filteredseepage with 95% trapping efficiency

- Can eliminate need forcostly sediment basins

- Upstream and downstream posts provide three-dimensional stability
