9. What is an example of floodproofing?

Some examples of floodproofing include the installation of watertight shields for windows and doors, use of sealants and membranes to reduce seepage of floodwaters through walls, and reinforcement of walls to withstand the pressures from floodwaters.

10. What materials can withstand a flood?
