BENEFITS & PROPERTIES
Radon Gas Mitigation
Open voids create a highly permeable layer for sub-slab gas collection and depressurization.
Enviro-Rock’s open-graded structure creates interconnected pathways beneath slabs, allowing soil gases such as radon to move freely toward collection piping or a depressurization system. Its foam-glass particles provide the structural fill layer while supporting below-grade radon-control strategies.
Sub-Slab Gas Control
The permeable aggregate layer helps direct soil gas toward a collection point beneath the slab.
Interconnected Gas Pathways
Open void spaces between particles create continuous pathways for soil-gas movement.
Multi-Function layer
Provides structural support, thermal insulation, and soil-gas permeability in one layer.
Why Radon Gas Mitigation Matters
A permeable sub-slab layer allows soil gases to move laterally toward a collection point rather than relying on isolated pockets beneath the slab. Enviro-Rock’s interconnected void structure can provide this gas-collection layer while also serving as lightweight structural fill.
Where active or passive radon-control systems are required, the complete assembly—including piping, sealing, membranes, and ventilation—should be designed in accordance with applicable building-code and project requirements.
Where Radon Gas Mitigation Makes a Difference
Foundations & Basements
Creates interconnected gas pathways below occupied below-grade spaces where soil-gas control is important.
Slabs-on-Grade
Provides a permeable layer beneath the slab that can support passive or active sub-slab radon systems.
