CJR Grocers — 140 ft of Failed Freezer Wall Replaced While the Store Stayed Open

Existing refrigeration plant retained on the operational sections of the CJR envelope. Refrigeration on the rebuilt 140 ft section isolated during demolition and panel install, then recommissioned against the new wall once the envelope was sealed and pressure-tested. No new condensing units or evaporators introduced. The rebuild restored the existing plant to full operating spec.

A 140 ft section of the freezer wall was cracking, with cold air leaking out at the failure points. The root cause was ground movement under the original concrete pad. The slab was shifting, which stressed the insulated panels above it from the base up. Once the panels crack, the vapor barrier breaks and the failure accelerates. By the time WFE was on site the wall section needed full replacement, not patching.

Yes, on most failure types. The CJR rebuild was sequenced around live grocery operations: refrigeration on the unaffected sections kept running, the failed wall came down and went back up in phases, and the recommissioned refrigeration brought the rebuilt section back online without forcing the operator to shut the facility down. Whether this approach works depends on the failure scope, how much of the refrigeration plant has to come offline, and whether temporary cold storage is needed to cover product during the work. WFE diagnoses on site before quoting the rebuild approach.

Ground movement under the original concrete pad. The fix involved pouring new concrete under the failure zone to address the shift, then installing new steel impact guards at the floor line, both to absorb routine forklift contact that contributes to base-of-wall damage over time and to add structural protection against the original failure mode. The rebuilt section is now protected the way it should have been from the start.
