Flooding and Historic Buildings
Flooding is one of the most significant risks to historic buildings from climate change. Many historic buildings are in areas where there is a chance of river or coastal flooding. Even more are at risk from surface-water, groundwater or sewer flooding.
Historic buildings need careful attention
Although most historic buildings are very durable and relatively resistant to flooding compared with much modern construction, they can still suffer substantial damage.
Older buildings behave differently to modern ones and as a consequence need much more careful attention after flooding. They are often built with more permeable materials like timber, lime mortars and plasters and soft bricks. These will absorb water and need to be able to dry slowly. Repair works need to consider how the individual building is constructed and the materials used.
