Woven Belted Silt Fence (WBSF™) 2 Stage
NTPEP Compliant
Patent # US 8,747,027
Woven Belted Silt Fence – 2 Stage is an alternative to wire back silt fence that does not require wire and / or net backing and was designed to address areas with the heaviest stormwater flow.
Silt Saver WBSF 2 Stage is a 36″ tall woven polypropylene geotextile with four >350lb. tensile strength belts woven into the fabric making this line of silt fence one of the strongest on the market. The internal belts used as attachment points allow this fabric to distribute the weight of stormwater and sediment throughout the system allowing the fence to hold maximum loads without additional support. The 2 Stage WBSF was designed specifically to meet the challenge of those areas on your site with heavier than normal stormwater flow. Heavy stormwater flow often leads to silt fence failures by creating undermining below the fence or over topping above, both of which threaten structural integrity and sediment retention. This 2 Stage fence was engineered with both controlled stormwater release and sediment retention in mind. Stage One above the ground line is 50 sieve to retain sediment with superior efficiency, while Stage Two provides controlled stormwater release allowing greater than 300 gallons per minute per square foot stormwater flow. This controlled stormwater release along the length of the fence allows the water to be more evenly distributed across the fence reducing the risk of failure at the lowest point. 2 Stage WBSF is available on pre-assembled hardwood stakes (1 ¾” X 1 ¼” X 4’) at 4’ centers for heavy duty or 6’ centers for medium duty sensitive areas. It is also available as master rolls of 500 or 1000 feet for application on wood or steel posts. Sourced and made in America.
