Building materials to protect against flooding

Whilst there are some areas of the country that are more liable to flooding, there is no harm in making a few small changes to your home to ensure you are protected should a sustained period of heavy rainfall cause flooding where you live.  

Whilst it is impossible to fully safeguard your home, in this article we look at some of the building materials you can use to help stop your home from flooding, or help to reduce the cost of recovery. 

What building materials are available?

Air bricks are an essential building material when constructing a house, as they help with airflow and will prevent moisture build up that could cause damp.  However, as they are generally fitted at ground level, they can be one of the first places where water will enter a home. 

If you do live in an area that has a high flood alert, or you have been flooded in previous years, it may be worth considering changing to flood resistant air bricks.  These can be fitted to existing vents and work in the same way, however they automatically close under flood conditions preventing water from flowing through them.  Alternatively, add air brick covers, which can be closed as water levels begin to rise, but you must remember to open them again once the water drops. 

We would also recommend fitting non-return, or check valves to drains and pipes as these allow water to only flow one way helping to prevent water from coming in. 

Is there anything I can do to the outside of my home?

In addition to picking up building materials to help protect the inside of your home, there are a couple of things you can do outside. Start with re-pointing any bricks and covering with a waterproof sealant to stop water from seeping through any gaps. 

Whilst your council will have a stock of sandbags that it will give to more at risk properties, there is no harm in taking matters into your own hands and speaking to your local builders merchant who will be able to help.  Place these where water could get into your home, such as at the foot of external doors. 

What else can I do?

It's not just about using building materials to make changes in a home.  By using ceramic floor tiles and rugs instead of carpet can help the clear up from a flood and reduce the cost of the recovery.   If you are at risk, another good option is to raise the height of low level electrical sockets to at least 1.5 metres above ground floor level, although this can be a costly process, so it's best to assess your chances of flooding first. 

If you get a warning, then start moving more high value items, such as TVs, game consoles and even sofas, upstairs to protect them.  Alternatively, it is possible to buy large sealable bags which you wrap around items such as cookers, fridge freezers, etc. 

Finally, make sure you regularly clear your drains and pipes as these will mean the water has somewhere to run away.
