Heated Driveways
Keep the heat where it matters.
Enviro-Rock is a lightweight foam glass aggregate used beneath heated driveways and snow-melt pavement systems where thermal efficiency, structural support, and frost performance are important. With a design thermal value of approximately R-2 per inch, it can provide an insulating granular layer beneath the heated pavement while also reducing heat loss into the underlying ground.
Key Uses
- Heated driveways
- Snow-melt pavement systems
- Heated walkways and pedestrian areas
- Heated patios and exterior slabs
- Pavement systems requiring thermal insulation
- Driveways over weak or compressible soils
- Frost-sensitive pavement applications
- Replacement for heavier conventional granular fill beneath heated surfaces
Overview
Heated driveway systems rely on directing energy toward the pavement surface rather than losing heat into the ground below. Conventional granular base materials provide little thermal resistance, allowing a portion of that energy to move downward.
Enviro-Rock combines structural fill and thermal insulation within the same granular layer. Its closed-cell foam glass structure provides a design thermal value of approximately R-2 per inch, helping reduce downward heat loss while its tested compressive performance supports the pavement assembly.

Key Performance Considerations
Thermal Insulation
Helps reduce downward heat loss so more thermal energy can be directed toward the heated surface.
Compressive Performance
Confined compressive performance supports the granular layer beneath loaded driveway and hardscape assemblies.
Freeze-Thaw Durability
Tested for repeated freeze-thaw exposure in exterior assemblies subject to seasonal moisture and temperature cycling.
