Do any of you have an experience repairing a concrete floor? The building I am in at work burned down years ago before we were the tenant. They left the floor and rebuilt over it. The floor has large pockmarks where the concrete was damaged. They are not very deep maybe an inch at most, but are hard on fork trucks and moving equipment around. It would be nice to be able to fill these spots. Anybody know of anything that will hold up to some extreme abuse?
