Performance Starts Below the Surface

Under-slab spray foam insulation improves energy efficiency and moisture control before your building is even finished. Installed beneath concrete slabs, spray foam adds insulation and structural support exactly where it’s needed.

Closed-cell spray foam insulation, namely, Walltite by BASF has been certified for use under concrete floors. This makes it an excellent choice to replace rigid board insulation when groundwater levels are not high.

Instead of dealing with boards prone to movement, twisting, and breakage, spray foam is applied directly onto the aggregate. This seamless application allows for straightforward installation of rebar and heating lines, as the spray foam can be walked on without fear of damage. The system offers both seamlessness and speed in installation, efficiently covering areas that would be laborious to achieve with rigid boards.

Spray foam also works to seal moisture and soil gas control. This is an approved system to replace poly, concrete, or rubber liners in crawl spaces for new construction. The spray foam insulation provides insulation for the floor at the same time as sealing it off from moisture and gases as per code.
