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 work sites during wet weather while allowing water to flow away.
Available in convenient 50m rolls. Cirtex® SiltFence meets the requirements of local authorities for a primary barrier against site run off.
SiltFence can seem complicated to install, but it is fairly simple.
Follow along our installation animation, or references our illustrations for details and requirements to meet the standard specification.
Super SiltFence is the combination of a double layer woven SiltFence material supported with a galvanised wire mesh for the more demanding conditions.
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.
Frequently Asked Questions
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.
SiltFence is used in a wide range of applications for containing sediment runoff. It filters out solids while allowing water to flow through.
SiltFence is to be installed with 200mm below ground returning upslope, 200mm below ground verticle, 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.
