The heating cable layout will depend from
the surface type.
Asphalt surfaces
Stages of works:
• Metal installation tape or mesh is placed on the
compacted (hard core) base, with the heating
cable attached to it – installation tape’s tongues
should be folded so that they would not
straighten up during asphalt rolling
• Power supply conductors (”cold tails”) in
asphalt should be positioned in the protective
metal installation conduit. Alternatively, power
supply conductors can be led out of the area
where asphalt will be poured out
• The 40-50 mm-thick layer of asphalt is laid out
manually – Stage 4
• The asphalt surface is rolled – Stage 4

Concrete surfaces
Concrete surfaces require epansion joints. Unreinforced
concrete slabs should be divided into expanded areas
of the surface no larger than 9 m
2
, reinforced concrete
flagstones – into areas no larger than 35 m
2
. The length
of the heating cables should be selected so that they
would not cross the expansion joints. Only the power
supply conduits (“cold tails”) can cross the expansion
joints. They are to be placed in a metal protective con-
duit of the length of approx. 500 mm.
