Sub-zero storage demands a concrete floor system engineered for the job. Thermal shock at entry doors, moisture cycling, heavy forklift loads, and constant cold all work against standard coatings. Gatineau Concrete installs urethane cement systems rated for freezer conditions, with the cold-temperature installation protocol that bonds properly to the slab. Free written estimate on every project.
Standard Coatings Don't Survive Freezer Conditions
Epoxy and standard polyurethane coatings fail in freezers because they cannot handle the combination of constant cold, repeated thermal cycling, and moisture migration through the slab. The concrete itself stays cold, and water vapor moves through it continuously, attacking the bond from underneath. Within months, the coating delaminates.
Urethane cement is formulated to cure at low temperatures, bond to cold-side concrete, and resist moisture migration. It's not a surface coating; it's a structural layer that becomes part of the slab. The install protocol matters as much as the material. We follow the manufacturer's cold-temperature procedure, which sometimes includes brief localized warming during cure to ensure the chemistry develops correctly.
We document the freezer's temperature range, door-opening frequency, forklift traffic volume and type, any chemical exposure, and your available shutdown window. This data determines which urethane cement system is right for the job.
Prepare slab at operating temp
The concrete is diamond-ground while cold to remove contaminants and old coating residue. Cracks are repaired with cold-compatible bonding materials. The surface is cleaned and left ready for the urethane cement application.
Apply cold-rated system
Urethane cement is mixed and applied following the manufacturer's cold-temperature protocol. Depending on the product, this may include brief localized heating during the cure window to ensure proper chemical development without disrupting freezer operation.
Verify bond and document
After cure at freezer temperature, we test the bond at multiple points across the floor. Documentation is provided for your facility records, along with the maintenance protocol for long-term care of the concrete.
The door zone problem
Entry Doors Create Thermal Cycling Stress
Every time a freezer door opens, warm air enters and the slab near the door experiences a temperature swing. This cycling creates differential expansion and contraction that standard coatings cannot handle. The door zone fails first, often within the first year of operation.
We specify urethane cement systems rated for the thermal cycle your freezer experiences, and we reinforce the door zone with additional material or a cove transition where engineering requires it. This handles the shear stress that kills standard systems. Coordinate with our broader cold storage services and any warehouse floor coating work in adjacent spaces.
Cold install, urethane cement, thermal cycling and door-zone engineering.
With the right cold-rated system, mostly yes. Some products allow install at freezer temperature; others require localized warming during the cure window. The right protocol depends on the system spec; we will explain the options.
Urethane cement handles thermal shock and constant cold dramatically better than standard epoxy. It bonds to cold-side concrete, cures at lower temperatures, and resists the moisture migration that destroys epoxy in freezer environments.
Door zones see the harshest thermal cycling and fail first on standard systems. We use systems rated for the cycle and reinforce the door-zone install where engineering calls for it, often with a cove transition that handles the differential movement.
Depends on the system and project size. Some installs can happen with the freezer cycling on a planned shutdown window; others require continuous freezer operation throughout. The project plan answers this for your specific install.
Properly installed urethane cement systems last decades in freezer environments with minimal maintenance. The wrong system fails within a year; the right system effectively becomes part of the freezer infrastructure.

What Gatineau Operations Say About Their Freezer Floors
Urethane cement install during a planned 48-hour shutdown. Freezer back to temp on schedule, floor has held perfectly through three years of daily forklift traffic and door cycling. Right system, right install.

Cold Storage Manager, Gatineau
★★★★★
Door zone replacement after the previous coating delaminated from thermal cycling. The new system has held through full year-round door operations. Engineering for the cycle was the difference.
Y. D5
Food Distribution, Ottawa
★★★★★
They explained the cold install protocol clearly and stuck to it. Bond verified at handoff, documentation provided for our facility records. Real cold-environment expertise.
Q. D5
Logistics Operations, Barrhaven
★★★★★
Phased install across a multi-cell freezer over several scheduled shutdowns. Each cell back to operating temp on schedule, no chain disruption. Real operational awareness.
