Heating of outdoor surfaces
It is possible to protect any area used for passage with the help of heating cables – pavements, paths, drive-up ramps, staircases etc. Special heating cables are used for these applications – robust structures with stranded resistance and wattages of 20–30 W/m. The heating can be provided by a heating circuit as well as a heating mat. For thoroughfares which are walked on, the heating element is placed in a sand bed or into a concrete slab, while in the case of stairs, terraces and similar areas the element is embedded into bonding cement. In thoroughfares used for driving, we unambiguously recommend that the heating element is placed into a concrete slab which will protect the heating cable from damage when the thoroughfare is used by a car.
Heliports are a specific category of installation of heating cables in concrete. These are often located on the roofs of hospitals or high-rise office buildings, and therefore the thermal expansion of the load-bearing structure must be taken into account here.
