Property-level protection (PLP) is a process undertaken by individual property owners to protect their homes and business from flooding. PLP includes resistance measures (the fitting of manufactured products, such as barriers and airbrick covers, aimed at preventing flood water from entering the property) and resilience measures (actions taken to minimise damage caused by flooding). It is essential to evaluate the options available through independent professional flood risk surveys to determine what will work best for you and your property.
- Barriers come in various shapes and sizes and can be fitted to openings such as doors, windows and even cat flaps. They provide a watertight seal to keep floodwater out of your home.
- Automatic flood doors are now available that require no manual deployment on receipt of a flood warning. Simply close and lock the door. These are of value where there is little or no warning of a flood and where residents would find it difficult to fit manual barriers.
- Non-return valves (NRVs) can be fitted to drains around your home to prevent floodwater backing-up. They can also be used to prevent backing-up and ingress of sewage in foul chambers.
- Airbricks can be replaced with automatically closing airbricks to create a seal and help limit ingress of floodwater into a property.
- Pumps can help keep floodwater at manageable levels for those at risk of rising groundwater entering through the floor of the property.
Even in the most prepared household, water can still find its way in. Measures like waterproof plaster, solid concrete floors and tiled floor coverings can reduce the time it takes to get back to normal after a flood. Other preventive steps include raising electric sockets above likely flood levels, to preserve electricity supply, and moving paperwork and valuables to higher levels to minimise potential damage.
