Whilst people may prepare themselves from flooding with flood barriers and doors, areas of vulnerability in the exterior of the building are often overlooked when selecting a flood defence. The two most common are overlooked in the exterior of a property are air bricks and the drainage system.
Designed to allow air flow into your home, it allows air to reach the floating floor – a timber frame at the bottom of a property that helps to support it. The timber and floor boards require air flow so rotting does not occur. The air bricks themselves can be easily spotted, taking on the appearance of a normal brick, but with holes or perforations allowing air in. With these holes in place though, it does mean that flood water can get into the property and 99% of the time they are overlooked.
Flood waters can be easily combated with one of our air brick solutions. An automatic air brick or smart air brick is designed to close off the moment that water touches it or rises to it. This is detected with a floating device inside the air brick (or vent). Usually the device is either a flap or floating ball.
Alternatively, you can purchase an air brick flood cover.
Why install an anti-flood air brick covers?
Air brick covers allow you to maintain necessary air flow to your property, ensuring you do not suffer from damp rot. Anti-flood air bricks can restrict the air flow to your property because they have a device inside the brick which is activated in a flood event. These devices (flaps or balls) restrict the air flow that normal air bricks provide.
- Air brick covers are easy to install, and do not require any expertise or concrete. This makes them more cost effective and quicker to install, particularly if you are retro fitting to a property.
- Air brick covers comply with Environment Agency guidelines on protecting your property from flooding.
- Air brick flood covers are quicker to install than alternatives, such as sand bags.
- Bright red cover to remind you to remove the cover once the flood risk has subsided.
During a period of flooding or sustained rainfall, if pressure builds up on the mains drainage system, you can get a fountain of water and raw sewage coming into the property, also known as back flow. 50% of all flood damage is caused by back flow, therefore we always recommend installing a non return valve. The best solution to prevent back flow is a drainage non return valve, which can be installed in the man hole or inspection chamber outside your house. The valves are a cost effective solution to the back flow problem, and can be installed in 1 minute. Retro fit non return valves require no tools to install.
If you cannot locate the inspection chamber outside your home, you will need to install an inline non return valve. This can be a big job, and requires digging a hole, cutting the pipe and installing the valve. We would recommend you speak to a drainage expert or plumber if you need to install an inline non return valve.
The size on the non return valve will depend on whether your building is a commercial or residential property.
- 110mm non return valve ar erequired for residential properties.
- 150mm non return valves are required for commercial properties.
