5. Know your flood resistance from your flood resilience
A combination of flood resistance and resilience measures offer the best way to protect your property and minimise recovery costs.
Flood resistance measures
Examples of products you can use to help minimise the risk of damage include:
- Doors
- Purpose-built flood-proof doors
- Flood barriers that can be installed in front of doors
- Raised door thresholds
- Walls and floors
- Damp-proof bricks
- Wall and floor coverings
- Sealing floors (tanking)
- Airbricks - specially designed covers that are easy to place over ventilation bricks
- Drains and pipes
- Non-return valves on drains
- Water inlet and outlet pipes
Don't forget to think about who will operate any flood defence products and whether they are physically capable of doing it.
Flood resilience measures
For bigger floods (when the floodwater is more than a metre high), it is important that water does enter your property. If it doesn’t, the pressure caused by its weight might inflict structural damage or even cause the building to collapse.
Here are some things you can do to reduce the damage floodwater might cause inside:
- Shelving - install high-mounted shelves for irreplaceable or valuable items
- Home entertainment - fix any audio-visual equipment (like TVs) to the wall at least 1.5 metres above floor level
- Skirting - fit water-resistant skirting boards or varnish them
- Pump - fit a pump in a basement or under-floor void to remove floodwater
- Walls
- Dry-line walls - use horizontal plasterboard or lime-based plaster instead of gypsum
- Get a special draining system for cavity walls
- Flooring - lay tiles with rugs rather than fitted carpets, as they can be rolled up and moved to a higher position
- Doors and windows - install synthetic, waxed or varnished window frames and doors
- Kitchen and bathroom
- Use water-resistant materials such as stainless steel, plastic or solid wood rather than chipboard
- Where possible raise fridges and appliances on plinths
- Electricals
- Raise electrical sockets, fuse boxes, controls and wiring to at least 1.5 metres above floor level
- If rewiring, bring cables down the wall to the raised socket so that cabling isn’t affected
