Concrete Freezer Floor Design

The major problem with concrete freezer floors is frost buildup under the floor which will cause the floor to lift or heave often destroying the floor and the walls of the freezer as well.

Concrete freezer floor design.

Industrial floor designresidential concrete slabs often have few design requirements to get between the contractor and completion of the job. The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation. Concrete curing in freezers is a unique experience. If the contractor knows what he or she is doing and knows what the customer wants then the lack of specifications is probably a good thing.

Typically air entraining admixtures are added to exterior concrete to increase the concrete s durability. Type and thickness of insulation this design guide is based on industry standards with a thermal conductivity of. Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure. Kwik bond is designed for concrete floor repair on frozen surfaces such as freezers coolers and holding boxes.

An atypical concrete job. Finished floor in freezer applications this surface is typi cally concrete. Thus shouldn t air be added to concrete for a freezer floor slab as well since the concrete will be exposed to freezing temperatures. It is not a good idea to cool a new freezer store quickly as it s more likely to crack especially around the door a high traffic area.

Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room. This concrete is also required to be strong enough to support heavy equipment traffic from forklifts and other machinery. As this surface does not generally affect the overall heat load this design guide assumes a 4 10 cm layer of concrete. When you think of exterior conditions you think of freezing temperatures.

In this case the minimal insulation in the freezer floor became saturated with water from floor washing operations further reducing its. Most residential projects only specify minimum concrete.
