So you have a cooler or freezer and the concrete floor is damaged. Probably near the entrance or where (2) slabs intersect.
Repair products using water are out. A water based product is going to either freeze before it cures or will not hit it's peak strength before a fork-truck runs over it. Not good.
What to do:
- Use a water based product anyway (naughty boy!)
- Raise the temperature
- Forget it and keep buying fork-truck tires (money to burn?)
Your best bet is an epoxy repair patch designed to be used in coolers or freezers. They are formulated for fast cure and high early strength. Remember, moisture in a cooler/freezer is your enemy, that goes for the patch you use too.
