Apparently the moisture content at the time of any foundation or slab pour might have been incorrect. If this is the case, temperature changes will cause the concrete to expand and contract. A good example of this is a buckle in a highway. It may be necessary to remove a section of flooring across the extent of the floor slab and insert a control joint or expansion joint cover to allow for movement with the contraction and expansion. A commercial building contractor should be a guide in this process. Good luck.
