For a limited time period we are giving away a free can of FloodFoam® worth £14.99 with every Airbrick starter pack. FloodFoam® is a unique waterproof expanding foam supplied with its own built in “genius gun” that makes for a really easy application. Unlike traditional expanding foams FloodFoam® remains flexible even when cured making it ideal to use where flexing and movement is required, such as sealing a door panel against floodwater where the levels will  rise and fall creating a change in the pressure against the panel. Use FloodKit FloodFoam as part of your flood defences.
