How it works
Easy to fit opening
A flexible but strong top ring sits securely in the most common UK gully openings.
Specialist woven netting
Drain Defender’s technical woven netting is specifically designed to catch up to 100% of materials over 2mm without reducing flow rate.
Replaceable hydrocarbon filter
A unique hydrocarbon filter catches toxic hydrocarbons, preventing them from being washed into the water system.
Superior
hydrocarbon
protection
Hydrocarbons are an unavoidable byproduct of the construction process, being emitted from plant equipment and chemicals commonly used in construction. When these toxic chemicals are allowed to leak into public waterways, the impact on wildlife and even tiny aquatic organisms can be devastating to our natural ecosystem.*
With its unique hydrocarbon filter, the R&B Drain Defender captures these harmful chemicals, protecting the environment and providing project stakeholders with peace of mind.

No reduction
in flow rate
The Drain Defender has been developed using specialist technical woven netting designed to capture up to 100% of silt and debris over 2mm and retaining high percentages of fine sediment without any detrimental impact on water flow.
You can rely on Drain Defender to protect drains and gullys from blockages even during the heaviest downpours.
Sustainable
by design
Drain Defender has been designed with sustainability in mind from the ground up.
When the woven netting gets full, simply remove, rinse and replace. The unique hydrocarbon filter is also fully replaceable, making it more cost effective and environmentally friendly than competitors over its lifetime.
Protects
waterways
The Drain Defender collects silt, hydrocarbons and other debris before it reaches the waterways, protecting the environment and reducing the need for expensive remedial works.
Fits standard sized gully pots
Unlike others on the market, the Drain Defender has been designed and engineered right here at R&B to fit the most common drain sizes.
Environmentally friendly
Thanks to it’s unique reusable design, the Drain Defender is inherently sustainable. And with longer lifecycle than any other product on the market, it helps reduce waste too.
