Geo-Seal provides a perfect blend of constructability and chemical resistance owing to its triple-layered composite design. Installed between the foundation slab of the building and the soil pad, triple-layered Geo-Seal eliminates vapor intrusion pathways and stops contaminant vapors from permeating through the slab and into a building.
Fully tested and proven highly effective against VOC vapor such as chlorinated solvents and petroleum hydrocarbons, as well as methane gas, Geo-Seal earns wide approval among various regulatory agencies across the country.
