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.

Cirtex SiltFence is manufactured from a robust UV stabilised yarn, providing 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 SiltFence can be limited if not installed correctly. We have put measures in place to ensure your SiltFence is a succcess. See below.

The 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.
