About Product
SiltFence is a UV stabilised woven silt control fabric consisting of strong, rot resistant, chemically stable long chain synthetic polymer materials, dimensionally stable with each other.
This fence is used as a means of retaining silt and sediment on construction zones allowing water to flow away and preventing silt polluting our waterways.
Available in convenient 50m rolls. Strol SiltFence meets the requirements of local authorities for a primary barrier against site run off.

Product Specs
Super SiltFence is used in applications where there will be excessive pressure on the fence or areas where high water concentration of large catchments are being controlled with the Super SiltFence. The wire mesh adds support to the double layer SiltFence material to prevent the fence from blowing out under large loads.
Super SiltFence is the combination of a double layer woven SiltFence material supported with a galvanised wire mesh for the more demanding conditions.

Frequently Asked Questions
What is SiltFence and why do I need it?
SiltFence is a black woven geotextile and in many areas it is a council requirement to prevent silt from washing from your site and into nearby waterways.
Where is SiltFence used?
SiltFence is used in a wide range of applications for containing sediment runoff. It filters out solids while allowing water to flow through.
How is SiltFence installed?
SiltFence is to be installed with 200mm down the side of the trench and 200mm running across the bottom of the trench, upslope. The fabric needs to be 200mm below ground vertically, and 600mm above ground level. SiltFence is to be supported by Y posts every 2m (when using soft wire) or 4m (when high tensile wire is used). SiltFence clips or pins are to be used every 200mm, attaching the top of the SiltFence to the wire.
What size is available?
Standard SiltFence is available in two sizes – 1m x 50m & 1.3m x 50m. Super SiltFence is available in one size – 1.2m x 50m.
