Finishing the exterior of a slab-on-grade floor
Insulating the exteriors of basements and slabs leaves you with needed to finish the exterior. In this video you see an easy fix to have the exterior surface secured by set concrete, while avoiding any thermal bridges in the process.
Finishing the exterior of a slab-on-grade can be made very easy with a little foresight. We have eight inches of Roxul Comfortboard on the exterior of our slab, and in order to create an finished surface we have included a concrete board inside forms that we have attached with tie straps that pass through the insulation and are anchored into the concrete. When forms are removed, we have a solid surface ready to parge.
