BASE MATERIAL
STEP 1.5
Prepare the site that you want to heat with SlabHeat Cable. This includes making sure all
utilities and obstructions are accounted for.
STEP 1.6
New concrete slab: Lay a smooth, well-compacted gravel base. Ensure proper slope and
drainage as required by local building codes to avoid water buildup in any heated or surrounding
areas. Follow local building code and construction guidelines for grade thickness and type.
Make sure you account for the total grade and slab thickness as required. The SlabHeat Cable
should be located no more than 1-1/2" to 2" below the finished surface of the floor. See page
4 for some typical SlabHeat installations.
Existing concrete slab: If the cable is to be placed on an existing pavement, make sure it
is inspected for any sharp objects, loose sections, or other potentially damaging issues that
could cause problems later. It is very important for the cable to be completely embedded.
The cable should be covered by a minimum of 3/4" of concrete.
STEP 1.7
New concrete slab: Attach reinforcement, such as wire mesh or rebar, over the base at
about 2 inches below the level of the top surface. You must use "chairs" or other appropriate
objects to raise the wire mesh to the correct level. The SlabHeat Cable will be attached to this
reinforcement later. It is very important for the cable to be completely embedded in concrete.
Protect or remove sharp protrusions by bending them over, capping, or cutting. Sharp edges
may damage the heating cable.
