Flood Protection & Defence
Protect your property from rising water, blocked drains and backflow with our range of flood protection and defence products. Whether you are in a flood-prone area or simply want added peace of mind, these solutions help safeguard homes and commercial buildings against unwanted water ingress. Many customers also combine flood defence with standard channel drains, heavy duty B125 channel drainage or threshold channel drains to direct surface water away from the building and reduce pressure on surrounding ground levels.
Anti-Flood Air Bricks
Standard air bricks are one of the first entry points for floodwater. Our anti-flood air bricks look and function like standard ventilation bricks but automatically seal when water levels rise, helping prevent floodwater entering sub-floor cavities. Available in Terracotta and Buff to blend with surrounding brickwork.
Air Brick Covers
Our air brick covers provide a rapid, temporary flood defence solution. A permanent frame sits around the existing vent, allowing the cover to clip on instantly when flooding is expected. Once the risk has passed, the cover can be removed to restore essential airflow.
Backwater & Non-Return Valves
Sewage and foul water backflow can cause significant internal damage. Our in-line backwater valves and non-return valves automatically allow waste to exit your property but block reverse flow from the public sewer. This also helps prevent rodent intrusion through pipework. For even greater protection, pair with a soakaway crate system to improve surface water dispersal around the property.
Flood Protection Bags
Flood protection bags expand when hydrated to create a firm, sandless flood barrier. Lightweight and easy to store, they can be deployed quickly to protect door thresholds, garages and outbuildings when heavy rainfall is forecast.
