Snow melting cables are designed to be easily installed beneath driveways and patios under asphalt, concrete or pavers in mortar to melt snow to keep the surface dry durning the snow season. Snow melting systems are usually available in 120 volt and 240 volt systems and are ideal for commercial and residential driveways and patios. During use, the paving material absorbs the heat generated from the snow melting cables and melts the snow and ice on the surface providing safe passageways.
