Directing Water To Drain Properly, On Sunken Concrete Garage FloorNovember 21st 2006
Q. I have a drain in the middle of my double car garage, the flow to drain is effective for my car which is parked closest to the house but any water that gathers on the far outside wall where the van is parked now flows to that wall instead of flowing to the drain. I have to cut away some drywall (which unfortunately was hung too low). I'm guessing the garage has settled.
What can I do to prevent the water from flowing to the far outside wall? If I can't do anything about that, is there a caulk that I can use to at least prevent the water from eventually rotting the 2x6 walls?
A. The main concern is the water affecting the outside wall structure. Rent a circular diamond bladed saw and cut the concrete slab in the area of the pooling water, directing the water back to drain grate.
This can be done by using a wedge cut 2x2 to run the sole plate of the saw on the groove or on an angle directing the water back to the drain. You will be required to cut multiple cuts to handle the volume of water. You may have to lower the grate to accommodate the water flow.
