Shield your property from flood damage in minutes with the Osmo Flood Barrier – 1.5m, the compact, fast-acting flood defence designed for regular doorways, garden gates and narrow access points.
Lightweight, flat-packed and ready to go, this self-inflating barrier expands when exposed to water, creating a watertight seal against flash floods, surface runoff and heavy rain. With a 1.5 metre length, it's ideal for standard front doors, side gates, sheds and conservatories – giving home users a simple, effective way to prevent water ingress.
Deploy in a few minutes with no tools, filling or faff. Just place it and add water with a hose pipe or watering can. Once fully activated, it rises to 90mm high, absorbing up to 30 litres of water. Need more height? Stack multiple barriers. Need coverage around corners? The flexible construction curves to suit your site.
Manufactured using at least 50% reclaimed materials, it’s non-toxic, non-hazardous and reusable depending on conditions. Whether you’re buying a single unit for your doorstep or a 34-pack for wider protection, the Osmo 1.5m flood barrier is a smarter, cleaner alternative to traditional sandbags.
