Siltfence

Cirtex® SiltFence is a high quality UV stabilised woven polypropylene silt control fabric used to prevent silt runoff entering our waterways.

SiltFence is a requirement to be used around construction and earthworks sites to prevent the silt running off the construction zone in an uncontrolled manner, polluting our waterways. SiltFence meets the requirements of local authorities for a primary barrier against site runoff.

Manufactured from a robust UV stabilised yarn, Cirtex SiltFence provides a strong and stable product that will last in the harsh conditions we find here in New Zealand. This ensures that there is no premature failure on projects sites resulting in costly contamination of surrounding properties and waterways.

The effectiveness of silt fences can be limited if not installed correctly. We have put measures in place to ensure your silt fence is a succcess. See below.

Plastic yarn or fibres used in this geotextile consist of at least 95% by mass of polyolefins, polyesters or polyamides, and contain stabilisers and inhibitors added to the base plastic to make the filaments resistant to deterioration due to ultraviolet and heat exposure.

Super SiltFence is a double layer product with a sewn joint and is also available from Cirtex. Super SiltFence requires Super SiltFence Wire Mesh to be placed behind the fence to give additional strength and support.

The SiltFence Portal consists of back-to-back anti–seep collars that are sealed and secured on both sides of a SiltFence or Super SiltFence and can be secured with additional waratahs for long term stability.

This unit is available for 100mm and 150mm solid novacoil pipes. This allows stormwater connection or dirty water diversions to pass through a silt fence whilst maintaining its structural integrity.
