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.
B. Concreting process using a wheelbarrow:
- Pay special attention when moving around the mats so as not to damage the cables.
- Protect the heating cable installation with a piece of plywood while moving the wheelbarrow around.
- It is important to install a plywood panel underneath the wheelbarrow before pouring any concrete
so the wheelbarrow buffer does not come into contact or damage the heating cables.
- Avoid using the same trajectory with the wheelbarrow. This will allocate stresses throughout
the entire installation.
4. The heating cable system must be encased with a minimum of 4” to 6” (10 to 15 cm) of concrete.
Note: It is imperative that the ENTIRE heating cable installation be encased in concrete. There should be
no jutting parts or heating cable visible.
5. If it’s necessary to replace the metallic structure for reinforced concrete, be careful not to catch any of
the cables with the tools.
6. Level the concrete in a normal fashion paying special attention not to catch any of the cable ducts used
for the cold conductor or temperature sensor
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.
