Foundation

The foundation walls for the new townhomes were poured offsite by Durham, North Carolina-based Ideal Precast. Trucked to the site, the walls were set into place by a crane in one day. Made of high-strength steel and concrete, the wall incorporates EPS insulation, which improves the basement’s thermal performance.

After these walls were set into place, a vapor and air barrier (Stego Wrap) and five inches of high-density insulation were installed under the slab and footers by Mount Rainier-based contractor Pete McAvoy. The foundation was completed with the addition of a slab and concrete block party walls.
