What surfaces can Tuff Cable be used for snow melting?

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.
