Installation Under Pavers

For paver applications, the heating cable should be covered with approximately 2 inches of sand before installing the pavers. Pavers should not exceed 4 inches in thickness.

Installation Under Asphalt

The WSM cable can withstand direct asphalt contact for a limited time until the asphalt cools. For asphalt pours exceeding 220°F, apply a 2-inch sand layer above the cable before asphalt placement. Rollers exceeding 2 tons should not be used directly over the heating cable. Hand rolling is strongly recommended.

Installation Under Concrete

For concrete installations, ensure the cable is embedded no deeper than 4 inches below the finished surface. Re-mesh or wire mesh is recommended to properly suspend the cable within the slab during the concrete pour.

Warranty & Maintenance

When installed according to Warmup installation guidelines and properly tested throughout installation, the WSM snow melting cable system requires virtually no maintenance during its operational life. The cable is backed by Warmup’s 10-Year manufacturer warranty and protected by the Warmup SAFETYnet installation guarantee.
