4.6 Concreting
1. Before the concrete is poured, measure the resistance
and cable insulation and record these values on line #3
of the measurement chart on the electrical panel label.
2. Switch the electrical fault indicator on BEFORE any
circulation on the concrete cables and BEFORE
the concreting process begins.
If the electrical fault indicator rings during the pouring
process, mark the location where the cable was damaged
using a stake. Delineate an area at least 2 ft 2 (0.18 m 2 )
around the location where the cable was damaged and
DO NOT COVER that area with concrete. Finish the
concreting process and call Ouellet Canada Inc.’s
specialists for a repair kit (OWC-KIT) used for repairing
the concrete cable.
3. Install the material required for the protection of the heating cables during the concrete pouring process:
A. When using a concrete pump:
- Pay special attention when moving around the mats so as not to damage the cables.
- Always place pieces of plywood or polystyrene foam underneath the pump hose, more specifically,
under the joints and connections to ensure they do not come into contact with the heating cables.
- Once the pump is activated and the concrete is pouring, always lift the end of the hose to ensure
it does not come into contact with the heating cables.
