When a cold store is installed at ground level, its low temperature will gradually transfer through the floor into the ground beneath. If this is allowed to happen then moisture, which is naturally present in the earth, will start to freeze. As this moisture turns into ice and expands, it pushes up on the floor above, causing the cold store floor to crack and bow. This often results in an uneven and unsafe floor and disruption to the racking. Once the floor itself is damaged, the situation can quickly deteriorate so that the entire cold store becomes un-useable.
To prevent this serious and very costly problem, specialists recommend a combination of insulation and low level heating in the floor of new cold stores.
Frost heave solutions
Thermatek® provide a range of frost heave prevention systems, which combine thermal insulation and energy-efficient, low-voltage heating. The heating elements are thermostatically controlled so that they apply just enough energy to prevent frost from forming in the ground. The insulation makes sure that the heat is directed into the ground without impacting the temperature of the cold store above.
