Flooding

According to a report published in 2014, 2.4 million properties are at risk of flooding from rivers or from the sea and nearly half a million of these are at serious risk. Three million are vulnerable to surface water flooding alone. Overall some five million properties (almost one in six) are at risk from flooding.

BS 85500 Flood resistant and resilient construction – Guide to improving the flood performance of Buildings has been developed to provide guidance on how to improve the flood resistance and resilience of buildings, in order to reduce the impacts of flooding from all sources, by the use of suitable materials and construction details. It applies to both new build and retrofitting of flood resistance / resilience measures to existing buildings. The standard recommends that materials and components used for the building fabric and finishes need to be flood resilient and / or resistant for new buildings or retrofit situations.

For insulation, a key factor in flood resilience is the ability of insulation to recover from the effects of immersion in water and to return to the expected level of thermal performance as soon as possible after the water has subsided. The use of closed cell insulation is recommended as this minimises the impact of flood water.
