Silt Fence

Silt Fence for Sediment Control

Silt Fences are an integral part of an erosion and sediment control plan for earthworks sites. Silt Fence is a temporary barrier of geotextile fabric used to retain silt and sediment and avoid silt pollution into rivers, drains and sensitive environments.

Silt Fence can be supplied with a full complement of silt fence accessories including Steel Y Posts, 2.5mm tensioning wire and safety caps. Silt Fences and Super Silt Fences are typically installed on earthworks sites at the downstream boundary or immediately downstream of soil stockpiles.




Silt Fence SF100X is specifically manufactured from UV stabilised polypropylene woven geotextile which meet Auckland Council TP90 Erosion and Sediment Control guidelines. Silt Fence SF100X is supplied in standard green and black colour combination.


The installation of silt fences follows local sediment control guidelines where supporting post spacing is typically no more than 2m apart and the silt fence extends to a height of 600mm above ground. Geofabrics supplied accessories provide support to the silt fence to meet the local council requirements. In all cases regular maintenance of silt fences is required which includes inspections after storms and removal of excessive silt deposits.
