Preassembled silt fence is an ideal barrier for sediment control around construction sites or wherever there is bare or disturbed earth. The woven geotextile used on silt fence is designed to filter out sediment from construction site run-off, yet allows clean water to pass through. The use of silt fence helps to ensure a free-draining, environmentally safe site. Silt fence is preassembled with wood stakes securely attached at 10 foot intervals. Color: Black.
