i have a garage that has sunk in the middle where the support column is due to a floor drain that was installed and goes nowhere. the ground has compacted in that area, causing the concrete to sink and crack, as much as 2 inches, i would like to temporarily remove the beam, bust the concrete out, refill with some good 3/4 inch crush, pack it down and repour the concrete. Is there some old school trick to determining how high and low the floor is in spots, cause i've been trying with a laser level, and it's level bubbles are untrustworthy, too cheap a tool. Any ideas? Don't worry i won't remove the beam without backup beams, lol...
