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.

Please note, the Osmo barrier will not inflate with salt water, so should be inflated with fresh water before being used against sea water.

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

This flood barrier has succeeded in keeping our garage dry. We cannot install something permanent as the garage is rented. Losing a star because gel residue stays underneath and you have to be very careful not to step on the barrier when entering the garage. Ordering another one as this stopped absorbing water after a few months.

Good product

It does what it says it will do and stops water , in my case from getting under my garage door

Osmo Flood Barrier

Absolute waste of money! Instead of protecting my garage door, it flooded the garage instead! Also split within one day and the gel contents spilled out everywhere. Terrible product!!

Keeping our crypt clean and dry

Unfortunately due to the heavy rainfall and high winds, this did not stop our kitchen and hall flooding.

delivery was prompt and as described.

Not put it into action so far so cannot award it 5 stars.
