Biodegradable Drain Guard

Drain Guards are engineered to capture sediment and oil from surface water before it enters gully drains—making them ideal for use on construction sites, farms, industrial estates, and other locations vulnerable to stormwater pollution or washdown runoff.

Constructed from sustainable wool and PLA biopolymer, these eco-conscious filters deliver high performance while supporting environmentally responsible site management. Integrated bypass ports ensure continued drainage even during heavy rainfall.

Simple to install directly into gully pots, each Drain Guard can trap up to 11 kg of sediment, sand, or debris and absorb up to 2 litres of hydrocarbons —all without compromising flow efficiency.
