Foam Glass Aggregate

Enviro-Rock is revolutionizing sustainable construction with foam glass aggregate made from recycled glass that is too challenging for any other purpose. Through innovation and substantial investment, we transform waste into a high-performance, eco-friendly aggregate that is very lightweight, fireproof, frost-proof, insect-resistant, and insulating.

Benefits

Enviro-Rock is a lightweight foam glass aggregate made in Canada from 100% recycled glass, designed to provide multiple performance benefits within a single material.

Its low density helps reduce structural loads, while its insulating, free-draining, and frost-resistant properties support durable, efficient building and civil applications.

Enviro-Rock also offers long-term stability, chemical resistance, and sustainable material performance across a wide range of projects.



Benefits & Properties
Explore key benefits and performance properties of Enviro-Rock Foam Glass Aggregate.

Enviro-Rock’s low density makes it easier to transport, move, and place than traditional aggregate. Its lightweight nature can also help reduce loads on structures and underlying soils while making installation more manageable on site.
Enviro-Rock provides insulating performance while also functioning as lightweight, free-draining fill. This can help simplify assemblies by combining thermal resistance with drainage and load reduction in a single material.
Enviro-Rock is made from recycled glass and is inherently non-combustible, making it well suited for assemblies where fire resistance and material safety are important. Unlike many lightweight fill and insulation materials, it does not rely on combustible components to achieve its performance.
Enviro-Rock’s porous structure can help reduce the transmission of sound and vibration through building assemblies. This makes it a useful material where acoustic performance is an added consideration alongside lightweight fill, insulation, or drainage.
Enviro-Rock is made from 100% recycled glass, turning a waste material into a high-performance building and civil product. Its lightweight nature can also reduce the amount of material being transported and supports projects looking to incorporate more recycled content and circular construction practices.

Enviro-Rock’s open structure allows water to drain freely through the material, helping reduce water buildup and the risk of frost-related movement. Its resistance to freeze-thaw conditions makes it well suited for foundations, backfill, landscaping, and other applications exposed to changing weather conditions.
Enviro-Rock is resistant to many common chemicals and does not provide a food source or habitat for pests. This helps it maintain long-term performance in demanding environments where moisture, soil conditions, or biological activity could affect traditional materials.
Enviro-Rock is designed to maintain its performance over the long term, even in demanding below-grade and exposed applications. Its stable glass structure resists decay, moisture damage, and biological breakdown, helping provide reliable performance throughout the life of the project.
Enviro-Rock’s free-draining, highly voided structure can create an effective sub-slab layer for radon gas collection and movement. Used as part of a properly designed radon mitigation system, it can help provide a continuous pathway beneath the slab while also contributing drainage and insulation.

Enviro-Rock can help reduce overall project costs by combining multiple functions in a single material, including lightweight fill, drainage, and insulation. Its low weight can also reduce transportation, handling, and structural demands, helping simplify construction and improve overall project efficiency.

Applications

Building Applications

Enviro-Rock provides a lightweight alternative to conventional aggregate for foundations and structural backfill. Its low density can help reduce loads on underlying soils and structures while also providing drainage and insulating performance within the same fill layer.
Enviro-Rock provides lightweight fill for rooftop landscapes, terraces, and amenity areas where reducing dead load is critical. Its free-draining and insulating properties also make it well suited for assemblies that need reliable drainage, thermal performance, and long-term stability.

Civil Infrastructure Applications

Enviro-Rock provides a lightweight, free-draining backfill option for utility corridors and trench applications. Its low density can help reduce loading on weak soils and buried infrastructure while also simplifying placement and supporting reliable drainage around the installation.
Enviro-Rock provides a lightweight fill solution for roadway construction and embankments where reducing load on weak or compressible soils is important. Its low density can help limit settlement while providing stable, free-draining fill for long-term infrastructure performance.
