650mm Flood Defence Barrier

Our 650 mm Flood Defence Barrier offers rapid, reliable protection for commercial, industrial, and residential sites at risk of flooding. Designed with the same proven engineering as our larger systems, the 650 mm unit provides a lower-height option ideal for doorways, vehicle entrances, pathways, and areas where full-height barriers may be unnecessary. 

Lightweight when empty but exceptionally stable once filled, these modular units are easy to transport, fast to deploy, and strong enough to withstand rising floodwater and high winds. The interlocking system allows you to build a continuous water-resistant wall of any length, giving you flexible protection tailored to your site. 

Benefits 

When flood waters rise, the majority of modular units automatically fill via self-filling holes. Once filled, the combined weight (and weighted universal keys) ensures that the assembled barrier holds back floodwater effectively. All units and keys incorporate hard-wearing gaskets for secure sealing. 

Because the barrier units interlock, you can create a continuous wall of any length required. Once deployed, the barrier remains stable even in strong winds, making it a more reliable and cost-effective solution than traditional sandbags.  

Installation 

The flood barrier is assembled by connecting the modular units using the universal key. The system is self-balancing, requiring no bolting. 

Thanks to its moderate size and weight, the 650 mm barrier can be rapidly deployed by a small team, making it suitable for quick-response flood protection. 

For cornering or wall adjacency, a Multi-hub unit can be used for rotation or angled assembly; enabling flexible layouts adapted to your property or site.  

When flood waters recede, the units drain themselves and become light enough to be carried away or stored for future use.
