Osmo Flood Barrier is a disposable super absorbent barrier designed to form a water-tight barrier protecting homes and businesses from the flow of food water. Available in 1.5 metre and 3 metre lengths, simply place in front of a door, activate with water, and it absorbs up to 30 litres of water, crystallises, and forms a water-tight barrier. Using super absorbent technology, the barrier absorbs water and binds together to create a flood protection sock. The flood barrier absorbs water on contact, making it quick to deploy, and the ideal sandbag equivalent.

Looking for an award-winning flood barrier that can be fitted in seconds, and protect your house against up to 60cm of water? Have a look at our famous Floodshield flood barrier.

flood barrier

Product description accurate and fit for small low profile flooding.

Gilly Megg
Excellent flood barrier

Efficiently diverted water away from my garden entrance in heavy rain and flood conditions - totally blocks water flow. Simple to activate and position before event, and then move afterwards, although outside storage means it doesn’t totally dry out, but takes up little space. No longer worried about flood warnings - used many times already.

Excellent temporary barrier

I’ve used this to direct water to a drain where the concrete hasn’t been laid properly and it’s worked well for 3 months and now I’ve just replaced it until I can get the concrete repaired

Sadly not what I was expecting

I was very disappointed with this product. It took an extremely long time to inflate and even then only managed half! I would not purchase another unfortunately.
