With sincere wishes of warmth and comfort!
In refrigeratories and big fridge-stores the temperature is kept at -20C - -30C. Frost is spread through all the constructions. Even if there is a good heat insulating the basement and soil freezing exists, that leads to ground swelling and basement damage. There is the same problem at artificial ice rinks. You can solve the problem of soil heating at refrigeratories by a hating cable.
