Vapor caps are critical components in environmental remediation projects, especially where subsurface contamination poses long-term risks to human health or nearby structures. These systems act as protective barriers—typically installed just above contaminated soil or groundwater—to prevent harmful vapors like volatile organic compounds (VOCs) from migrating upward into buildings or breathable air zones.
Often used at former industrial sites, brownfields, or locations undergoing redevelopment, vapor caps help bring properties into compliance with environmental safety standards. When combined with other remedial measures, they contribute to risk mitigation, regulatory approval, and project viability.
Elastizell of Wisconsin brings unique value to vapor cap installations through our use of low-density cellular concrete (LCC) as a protective layer. LCC offers excellent sealing capability, uniform coverage, and the added advantage of being both lightweight and self-leveling—ideal for capping irregular surfaces or hard-to-reach areas. Unlike traditional soils or gravel, our solution reduces the risk of vapor intrusion while minimizing additional load on the subgrade.
With six decades of field experience and a reputation for precision work, Elastizell supports environmental engineers, remediation specialists, and developers across Wisconsin. Our in-house batching systems and union workforce ensure consistent quality and quick deployment, even on tight timelines or active remediation sites.
