I have a concrete porch that sits about 2 feet off the ground; it has a brick foundation and most of it has a screen porch on it. The section that is not under cover does not drain when it rains. I have to squeegee the water off. Obviously when it was built; no allowance was made for drainage. Are there any solutions to correct this. Keep in mind that the floor is continuous from the screened portion to the open portion of the floor.
