Super Silt Fence Installation
Super silt fence combines standard geotextile filter fabric with a chain-link or welded-wire support backing, giving the barrier significantly more structural strength than conventional silt fence. LES installs super silt fence wherever standard fencing has failed, where flow concentration or slope length exceeds what standard fence can hold, or where a permitting authority requires enhanced protection adjacent to wetlands or other sensitive receiving waters.
What’s Included
- Chain-link or welded-wire backed fabric installation
- Reinforced post spacing and embedment for higher structural load
- Application at flow-concentration points identified in the SWPPP
- Installation adjacent to wetlands and other sensitive receiving waters where required
- Replacement of failed standard silt fence with super silt fence where conditions warrant
Technical Notes
The wire backing carries the structural load while the geotextile provides filtration, allowing the barrier to withstand higher hydrostatic pressure and physical impact than fabric-and-stake fencing alone — a meaningful difference on long slopes or in areas with concentrated stormwater flow.
Frequently Asked Questions
What's the difference between silt fence and super silt fence?
Super silt fence adds a chain-link or welded-wire backing behind the geotextile fabric, giving it far more structural strength. It's used where standard silt fence is undersized for the flow, slope, or sensitivity of the area it's protecting.
When does a project require super silt fence instead of standard fence?
Common triggers include repeated failure of standard fence, long or steep slopes that concentrate flow, and proximity to wetlands or other sensitive receiving waters where the permitting authority or design engineer specifies enhanced protection.
