Build Your Dream Home On A Superior Foundation

Nearly Everything Is Insulated In The Xi Wall Precast Concrete Foundation System, Including Corners, Studs And Bond Beams.

  • Special engineering makes the Xi Wall thermally isolated and insulated from the exterior elements. The foundation wall is monolithically poured (poured all at once) with high-strength concrete for solid structural integrity and reinforced with steel rebar and polypropylene fibers.
  • The Xi Wall’s special high strength, low-water concrete mix also requires no additional damp-proofing, benefiting from technology developed for the original Superior Walls precast concrete system. And the Xi Wall meets or exceeds energy conservation requirements from both the 2009 IECC and the 2009 IRC in most climate zones.
  • The high-tech engineering and numerous advanced features of the Xi Wall make it the precast concrete foundation system of the future and the only choice for selective architects, builders and home buyers.
