Last summer we decided to get our garage floor coated with epoxy.
We had a section that was cracked (see first photo) and hired a concrete guy to repair it (see second photo). He put rebar every 16" to join the old and new concrete.
We waited a month for it to cure, then we had the epoxy floor installed by a professional.
The next spring, we noticed a long crack along the joint of the new/old concrete.
I am nervous that if we don't fix that crack, water will get under the epoxy and ruin the coating.
My questions:
- Does it seem like the initial repair to the concrete was done poorly? Or is cracking at the joint normal?
- Does anyone know how to fix the crack without completely redoing the entire epoxy floor?
- If I fix the crack, should I expect it to get worse every winter? (I live in MN)
