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 using a metallic structure for reinforced concrete, pay special attention to the cables while moving around
the reinforcement structure. Make sure enough wedges or bricks have been used to ensure the structure can
withstand any shifting as well as the weight of the concrete, without varying in height. 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 lead or temperature sensor.
