Flood resistant building technology developed by BRE

Created: February 1, 2017. Updated: March 12, 2018.

The UK’s Building Research Establishment (BRE) has developed a ‘flood-resilient prototype house’ to show how homes can be protected against flood damage.

BRE has developed the ‘Resilient House’ to show how practical measures can be installed in a home to prevent flood water entering a property.

The measures developed in the house aim to not only help prevent flood water entering a building, but also aid rapid recovery after any flooding, reducing the cost and disruption of repairs.

  • BRE recommends the use of floor and wall membranes which can channel water towards floor drains;
  • an automatic sump pump that stops water rising through the floor and disperses water quickly should it get in;
  • one way valves fitted to the toilets and sinks to prevent flooding via sewers.

Other solutions include: flood resistant doors and windows; water resilient walls and insulation; a resilient kitchen with moveable kitchen units.

Different types of water resilient insulation have been used in the house including injected cavity wall insulation, thermal board and PUR spray foam. Other practical issues have also been addressed, such as how to improve floor insulation, where to place electric sockets and home appliances and how to seal off areas where water could enter the property.

BRE says the aim of this project is to show contractors and householders in a tangible way that resilient repair isn’t as challenging or difficult as they may think it is.

BRE has also launched a new certification scheme and training courses aimed at property flood resilience surveyors.
