Concrete Flat Roof
Posted: Mon Sep 03, 2007 3:51 am
My concrete roof garage (designed to be a roof top deck) does a great job of collecting water whenever it rains. In the middle, about 10-20 cm (2 inches) or so of water collects every time it rains. I'm wondering if there is a light weight material that I can put down to fill in the ponding area and divert the water off the end of the garage? Or if there are any other possible solutions.
