Economy Silt Fence Fabric (1m x 50m roll)
Protect waterways and comply with sediment control regulations using this economy-grade polypropylene silt fence. The UV-resistant 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.
Uses of Silt Fence Fabric:
Ideal for short-term civil engineering and domestic projects requiring erosion control. Install as an entrenched vertical barrier to flank exposed soils or border construction perimeters, trapping harmful silt through settlement and filtration. Specifications:
Dimensions: 1m (H) × 50m (L).
Material: Woven polypropylene tape yarn.
Weight: 5kg per roll.
Key Features & Benefits:
- Economical Construction: Cost-effective polypropylene for budget-conscious sediment control.
- UV-Resistant Fabric: Woven material withstands harsh Australian/NZ outdoor conditions.
- Lightweight Design: 5kg roll enables easy handling and installation
- Compliance Protection: Helps avoid fines and prosecution for sediment control non-compliance.
Key Requirements for Silt Fences (based on guidelines):
- Material: Woven 100-micron geotextile fabric is required; do not use shade cloth.
Installation
- Depth: Dig a trench 200mm deep by 100mm wide, place the fabric in it, and backfill with soil.
- Support: Use waratahs (posts) driven at least 400mm deep, placed on the downhill side.
- Height: The fence should stand 600mm above ground level.
- Positioning: Install on the downhill side of disturbed areas, with ends angled 2m up the slope to prevent water bypassing the fence.
- Maintenance: Regularly inspect and remove accumulated sediment, and move as construction progresses. 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.
