BASE MATERIAL
STEP 2.5
Prepare the site that you want to heat with SlabHeat Cable. This includes making sure all utilities and obstructions are accounted
for.
STEP 2.6
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 2.7
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.
Optional finished floor covering should
have a maximum R value of R3.
