Resurfacing a garage floor or pouring new
Resurfacing puts a new top layer on the slab you already have, so it usually costs less and keeps you out of the garage for less time, but it only lasts if the slab underneath is solid. A new top over a floor that's still moving will crack right where the old one did. When the wear is only on the surface, I'll tell you to resurface. When the ground has given way, I'll tell you that too, and why replacement is the honest answer.
