The first two sources examine the impact of floods and extreme weather events on individuals, communities, and properties. These sources provide guidance on how to mitigate the effects of flooding and increase resilience to future flood events, including detailed instructions for constructing and modifying homes to be more flood-resistant. The third source examines the use of a specific construction system that creates a watertight seal between walls and concrete slabs during the construction of buildings. This system ensures that buildings remain protected from water ingress and maintain their structural integrity over time.
