All Tuff Cable snow melting systems are custom-designed to ASHRAE standards, taking into account the project’s geographic location, local snowfall data, surface area, and slab type. Heatizon’s design team calculates the required wattage, run spacing, and transformer sizing for each project. This design service is included with every Tuff Cable system and is provided before materials are ordered. Layout drawings can be provided for special circumstances and/or large/specified projects.

Tuff Cable is suitable for snow melting in concrete, asphalt, mortar beds under pavers or stone, and overlay systems over existing surfaces. It is used for driveways, walkways, entryways, parking areas, loading docks, stairs, and ramps — both residential and commercial. It can also be installed under pavers in a sand or mortar bed, and can be retrofitted into existing concrete or asphalt via saw cut.

Yes. Tuff Cable can be retrofit into existing concrete and asphalt surfaces using a saw-cut method. Channels are cut into the existing surface, Tuff Cable is laid into the channels, covered with a backer rod, and the surface is patched with a compatible overlay material and/or a sealant. This retrofit approach delivers performance equivalent to a new-pour installation at a fraction of the cost and disruption of full removal and replacement. Heatizon’s design team provides retrofit layouts and specifications as part of the standard project design service.

The Joint Jumper Kit is a Tuff Cable-exclusive accessory that allows the heating element to safely bypass expansion joints and control joints in concrete installations. Without it, running a heating cable directly through a concrete joint creates a stress point where cracking or movement in the slab can damage or sever the cable. The Joint Jumper Kit connects the Tuff Cable to a cold lead that passes under the joint, then reconnects to the Tuff Cable on the other side — allowing the concrete to move and shift without putting mechanical stress on the heating element. This makes Tuff Cable the only snow melting cable that can be reliably installed across multi-section concrete slabs, stairways, and driveways with multiple expansion joints.
