Concrete cracked repair
Concrete cracked repair
(OP)
We're operating a meat processing plant with Freezers operating between -18°C to -27°C. The two huge freeers is separated by a an insulated wall with a roll-up door. Problem now...There's A crack along the opening of this door 2 to 4 inches wide and around 2 meters in lenght. How we are going to rectify this? We cannot shutdown or raise the temp to allow for concrete to dry. Is there any method applicable?

The crack was a failed in concrete. I cannot confirm the real cause but it seems a thermal movement. My real concern is when hotair below condensed then freezes the whole or huge part of the flooring might raise. Is there any fillings that we can use to fill the gap or cracked?
Thanks a lot

I still don't think I understand the problem or cause.

Does the roll-up door separating the freezers pass many heavily loaded fork lift trucks? Is there other machinery near the doorway? How is the door anchored to its lintel? How much of the wall surrounding the doorway is subjected to freezing? What else is above the doorway? Does the wall receive other thermal input/outflow?
The previous commentors have given you good advice. You need the services of a consultant.
Good luck.

The subject door is not a traffic one. The door was merely a connection between the two huge freezers with the same temp also. The the door was simply an opening on the insulated wall (about 6" thick. No other installation under the slab of the freezers other than perforated pvc pipes intended to trap hot air. The pipes burried on compacted soil and gravel, lean concreate, an insulation material then the concrete slab. the insulated wall intersects with the insulation on the flooring.
I am wondering if the injection of grouting will work.
Thanks
