Driveways and ramps
For all outdoor installations, care must be taken whilst covering the heating cables.
Do not drop stones or slabs on the heating cable. Asphalt should not have a higher temperature than approx. 160°C (320° F).
After placing the heating cables correctly, they manually should be covered by a thin layer of asphalt before the thicker layer is laid and compacted.
If the heating cables shall be moulded in concrete, it is important that the underlay is stable, and that the concrete is compacted.
