Protect your property from rising floodwater with the Osmo Flood Barrier – 3m. Ideal for garage doors, shutter doors, footpaths and driveways, this barrier expands rapidly when soaked with water, forming a watertight seal to block ingress.
With a compact flat-pack design, it takes up minimal storage space – perfect for homeowners and small businesses who want fast protection during flash floods. Simply unroll, add water, and let it self-inflate in minutes. Once activated, it rises to 90mm high and absorbs up to 30 litres, creating a resilient reusable barrier.
