In cold stores where the temperature constantly lies between -20 and -30ºC, cold will still be released to the surroundings even though the floor is well-insulated.
This means that the materials, which are in contact with the ground/soil, such as foundation and floor areas, will absorb the cold and leave the ground to freeze.
The water content in the ground soil will expand and this can cause considerable damages due to frost erosion.
The same problem also appears in ice rinks and threshold heating. This can be avoided with frost protection systems available from Devex Systems .
