Green Roofs & Terraces
Build depth without the weight.
Enviro-Rock is a lightweight foam glass aggregate used in green roof, rooftop landscape, and terrace assemblies where reducing dead load is critical. At approximately 200–240 kg/m³, it can replace heavier granular fill while providing a free-draining, insulating layer beneath growing media, pavers, and other rooftop finishes.
Key Uses
- Green roof build-ups
- Rooftop gardens and landscaped areas
- Terraces and amenity spaces
- Beneath pavers and pedestal systems
- Lightweight fill over structural roof slabs
- Drainage layers beneath growing media
- Deep-fill rooftop assemblies
- Areas requiring additional thermal insulation
Overview
Green roofs and terraces can require substantial fill depths to accommodate growing media, planters, drainage, pavers, and changes in finished elevation. Using conventional aggregate for these build-ups can add significant weight to the structure.
Enviro-Rock provides a lightweight, free-draining alternative that can be incorporated beneath landscaped and hardscape areas. Its approximately 42% void space supports drainage through the fill layer, while its low density makes it particularly useful where deeper rooftop build-ups are required.

Key Performance Considerations
Reduced Dead Load
Creates substantial rooftop build-up depth while limiting additional dead load compared with conventional granular fill.
Compressive Performance
Confined compressive performance supports lightweight fill within loaded rooftop landscape and hardscape assemblies.
Drainage & Permeability
Provides an open, free-draining layer beneath growing media, planters, pavers, and other rooftop finishes.
