I'm planning to grind the edge of a concrete slab to slope away from the garage door. How am I about to mess this up?

Important details: - 25x25 metal garage on a slab in central NC with 2 - 9 foot wide, West facing garage doors - Slab slopes ever so slightly down towards the east. Like, 2 inches over the entire 25 feet - The roof doesn't overhang anywhere - When it rains if there's even a little bit of West -> East wind, water hits the garage doors, pools on the 6 inches of exposed concrete, and then runs into the garage. - Zero outward slope was added to the rim of the concrete during the pour The plan is to use a concrete grinding pad on an angle grinder to cut a slope away from the garage into the edge of the concrete up to the garage doors. Doesn't need to be much, like 1 inch over 8 inches. So, what are the ways I might screw this up? Safety concerns, properties of concrete I'm not accounting for etc. submitted by /u/IPlayTheInBedGame [link] [comments]
