Final answer:
To ensure a building is floodproofed, it's important to check elevation above the base flood elevation, that materials and utilities are flood-resistant and appropriately elevated, and that sealants and barriers are properly implemented to prevent water ingress.
Step-by-step explanation:
To ensure that a building is floodproofed, there are several aspects that need to be checked. Building codes in many More Developed Countries (MDCs) ensure that safety requirements are met for a house to be considered safe and livable. When floodproofing a building, these codes commonly highlight the importance of the following three things:
- Elevation: The structure should be elevated above the base flood elevation (BFE) to reduce the risk of floodwaters reaching critical areas. Checking how the building is elevated, including the use of stilts, piers, or mounds, is essential.
- Materials and utilities: The building materials should be resistant to flood damage. Utilities such as electrical systems, heating, ventilation, and other services should also be elevated and designed to prevent water entry or minimize damage if inundated.
- Sealants and barriers: Use of sealants to prevent seepage of water into the building and barriers like levees or floodwalls to protect against rising water levels. Proper implementation and maintenance of these barriers are crucial for effective floodproofing.
These measures, while sometimes costly and mandatory, are implemented to protect the safety of inhabitants from flood-related disasters.
