Super Silt Fence Fabric (1.3m x 50m double layer roll)
Our double layer super silt fence fabric is quick and easy to install on site with a built-in marker strip showing the embedment depth, making installation fast and hassle-free.
Protect waterways and comply with sediment control regulations using this heavy duty-grade polypropylene double layer woven silt fence. The UV-resistant dual layer barrier intercepts sediment-laden runoff during earthworks and construction, preventing contamination of sensitive aquatic environments while helping you avoid prosecution and on-the-spot fines. Specifications:
Dimensions: 1.3m high (2.6m folded) × 50m (L).
Material: Double layer woven polypropylene tape yarn.
Weight: 12.5kg per roll. Differences Between a Silt Fence & Super Silt Fence:
Silt fences are temporary sediment barriers using single-layer, geotextile fabric on wooden / steel stakes for low-flow, small catchments. In contrast, Super Silt Fences are robust, high-strength, double-layer fabric systems reinforced with wire mesh or multiple fence wires and steel posts, designed for steeper slopes and higher-volume, larger-catchment runoff.
If this roll of fabric is used to erect a Super Silt Fence, please note the following regulatory requirements: Key Requirements for Super Silt Fences (based on guidelines):
- Fabric & Support: Use two layers of heavy-duty, woven 100 micron geotextile fabric.
- Structure: Secure wire mesh and fence fabric to 1.8m (minimum) long Y-posts (Waratahs) spaced no more than 2m apart.
- Tensioning: Install 2.5mm da (minimum) high-tensile (HT) galvanised wire at 400mm and 800mm height for support.
- Trenching: Excavate a 200mm wide x 300mm deep deep trench. The fabric must be buried at least 300mm into the ground and backfilled.
- Installation: Installed along the contour to manage sheet flow - not suitable for concentrated flows (i.e. not in watercourses or gullies).
- : Short fence (minimum 2m in length) must project upslope at intervals to prevent end-around flow.
- Inspection: Regularly inspected and maintained; sediment must be removed when it reaches 50% of the fence height.
- Stability: Ensure the fabric is supported and (if necessary) install safety caps on Waratahs.
