50m Silt Fence Kit for Erosion Control
(Please get in touch if you require a different length silt fence).
This handy silt fence kit contains everything you need to erect a 50m silt fence:
- 30 off x 1.5m long steel Waratahs
- 1 x Pack of plastic safety caps (100 per pack)
- 1 Pack of silt fence butterfly clips (200 per pack)
- 1 x Roll of high quality silt fence fabric (100m long x 1m high)
- 1 x Coil of galvanised wire (300m long)
- 2 x Wire strainers / tensioners
- 1 x Pack of 200mm cable ties (100 off)
Applications of Silt Fences:
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.
For longer term and more robust projects possibly consider erecting a Super Silt Fence instead.
Key Requirements for Silt Fences (based on guidelines):
- Material: Woven 100-micron geotextile fabric is required; do not use shade cloth.
- 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.
