The materials

Silt Socks are crafted from high-strength, UV-stabilised fabric sock material which is filled with locally acquired arbour chip, designed to protect waterways while minimising environmental impact.

The stuffing

Each sock is filled with biodegradable wood chips, sourced from local arborists. Using our purpose-built machine, the biodegradable wood chips are press packed into the casing material which creates the perfect product to trap and filter sediment and silt while allowing water to flow and escape your work site.

Silt Socks provide an effective way to safeguard waterways by trapping sediment and contaminants, ensuring only clean water passes through.

FAQs

What are the Silt Socks made of?

Silt Socks are crafted from high-strength, UV-stabilised fabric sock material which is filled with locally acquired arbour chip which provides a fast and effective solution for controlling sediment runoff on project sites and protecting waterways from contamination.

The lifespan of a Silt Sock depends on factors like weather conditions, site usage, and exposure to heavy water flow. Generally, they last 6 to 12 months in typical conditions but may need replacing sooner in high-impact areas. Regular maintenance and monitoring can help maximise their effectiveness.

Using a Silt Sock is an effective way to control sediment runoff, preventing soil erosion and protecting waterways from contamination. They are easy to install, environmentally friendly, and made from durable, stabilised materials. Plus, choosing Silt Sock supports the Wai-Ora Trust, meaning your purchase helps fund local environmental and community initiatives.
