I am worried about the damage that rainfall causes when it floods houses. I saw an interesting concept at an outdoor restaurant while visiting Nice, France. It is a thin rubber sheet folded in two and attached to the outside door base. About a two-inch flap is left hanging below the door. That excess flap lies on the ground and thereby covers the gap below the door.
I hope someone in Pakistan can also make this simple contraption and save their houses from water damage during the monsoon rain.
