Answer 2

For the most part, houses in such regions are based on elevated foundations. Bringing the foundations up in wet/flooding climatic zones is perfect as it likewise finds cooling breezes under the house. Wet sealing or dry-sealing opposes water damage.

The steeply inclining rooftop will enable the water to keep running off and maintain a strategic distance from it gathering on the rooftop, adding undesirable weight to the rooftop, and harming the common setting of the concrete/RCC.
