Our garage floor appears to have a slight dip just inside of where the overhead door closes. In the winter, water pools in these dips which is quite dangerous and slippery. The constant water has also caused concrete damage. We patched some of the damage last summer but now have new areas that are crumbling. We want to repair the dip and then seal the floor. We are thinking about using a self leveling floor resurfacer and then seal it with epoxy. We are concerned that using this approach may not fix the problem as we would not have a proper slope to the whole garage floor. Some suggestions and guidance would be greatly appreciated.
