I have a crack across the entire front of my garage floor. I believe that the crack was caused by a poor drainage issue that has been corrected. The drainage issue also caused the pavers in front of the garage to sink.
Although I believe the drainage issue was fixed, I'm not terribly confident in the base under the cracked concrete or the pavers. Would a complete cut-out of the cracked area (probably about 12 inches by 20 feet), repair of the base and replacement of the cracked area be the better of the two options given the base may (or may not) be compromised?
What is the best way to fix the garage floor? Should I cut out about 12 inches of concrete (between the pavers and the main garage floor), tie into the existing floor with rebar and then pour new concrete? Is there a better solution? Is this a DIY project or should I hire a professional? I have some (although limited) experience with concrete.
