Walk in freezer concrete floor construction requires a specially cured solution that can handle constant sub freezing temperatures.
Concrete freezer floor design.
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.
Industrial floor designresidential concrete slabs often have few design requirements to get between the contractor and completion of the job.
Most residential projects only specify minimum concrete.
When you think of exterior conditions you think of freezing temperatures.
Moisture from the ground below the box is drawn toward the cold freezes expands and so on.
This concrete is also required to be strong enough to support heavy equipment traffic from forklifts and other machinery.
Freezer floors also experience a secondary contraction when cooled to below zero temperatures and it s not unusual to see a 10 to 15mm gap between the concrete floor and the insulated wall panels.
In this case the minimal insulation in the freezer floor became saturated with water from floor washing operations further reducing its.
Kwik bond is designed for concrete floor repair on frozen surfaces such as freezers coolers and holding boxes.
Finished floor in freezer applications this surface is typi cally concrete.
An atypical concrete job.
Concrete curing in freezers is a unique experience.
The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation.
As this surface does not generally affect the overall heat load this design guide assumes a 4 10 cm layer of concrete.
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.
Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure.
Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room.
Thus shouldn t air be added to concrete for a freezer floor slab as well since the concrete will be exposed to freezing temperatures.
