Beginning in February 2006, UMix will begin stocking Mirafi Silt Fence. The silt fence structures, specially developed fabrics on supporting posts, are designed for efficient control of sediment run-off from construction sites. Installed correctly in the field, the sedimentation control fabric in silt fence structures functions as a filter and a run-off flow velocity check. Fine-grained sediment is trapped by the fabric while storm water run-off may pass through the fabric at a moderate rate. Contact UMix for your silt fence needs.
