How they work

WHEN floods strike you have little time to act.

FloodSax® are transformed from being as light as a pillowcase to become as tough and heavy as sandbags within minutes

Twenty fit into a cardboard box so can be ready for action anytime, any place, anywhere unlike sandbags that need vast warehouse storage space, are heavy and expensive to shift and require huge manpower and lorries to get them to the scene. If you think councils will react quickly to a flooding emergency by providing you with sandbags you are, unfortunately, burying your head in the sand.

Countries worldwide are being devastated by floods and in the UK alone more than 5.5 million – or one in six properties – are at risk of flooding but anyone can face a flooding emergency in their home such as a burst pipe at any time.

The semi-porous inner liner within FloodSax® contains gelling polymer which absorb water to become taut in just over 3 minutes. Once the water is in there, it stays there and the bags act just like sandbags to keep floods at bay. They are designed so they mould into doorways to keep floodwater out.

In short, FloodSax® take away the risk and are incredibly easy to deploy.

Stopping floods

FloodSax® are exceptionally tough and can stop a powerful torrent of water in its tracks. Just look at the video of how they saved a Yorkshire company from being flooded and check out how this powerful water jet fails to shift FloodSax®. They have even been known to hold back the sea.

Diverting water

And then there are times when you might want to divert water such as on this road where it was being pumped out of a flooded residential area and back into a pond or deep. British Waterways use them in canal locks undergoing renovation to keep water seeping in away from its staff carrying out the work. People use FloodSax® outside their homes to divert water away from airvents and directly down open manhole covers in to the sewers.

Home emergencies

But they can also be vital in those little domestic emergencies. If you have a cracked pipe, your toilet has a blockage and is overflowing or water is pouring out of your bath, pop a FloodSax® under and it’ll soak up the water.If your washing machine has sprung a leak put a FloodSax® in front to stop it spreading. And after the flood has finished FloodSax® can play a vital role in the clean-up and recovery stage. Pop them on the floor and they will soak up all the flilthy floodwater with each bag absorbing 22 litres.
