How can I protect against floods?

Flood protection products




Warning!

In cases of severe flooding (where floodwater rises above 1 metre) keeping water out of your property can be more harmful than letting it in. The stress on the building caused by that amount of water can damage the structure and foundations of the building. Therefore you should never block doors, windows or air-vents over 1 metre in height.
