Why Builders and Homeowners Rely on KOI Superior Walls

The Extra-Insulated Wall Foundation System
Almost Every Element Of The Xi Wall Precast Concrete Foundation System Is Insulated, Including Corners, Studs And Bond Beams.
- The Xi Wall’s distinctive design keeps it thermally isolated and insulated from the exterior elements, producing home energy savings.
- The precast concrete wall panels are monolithically poured—cast all at once—using high-strength concrete for solid structural integrity, then reinforced with steel rebar and polypropylene fibers.
- The Xi Wall’s specialized high-strength, low-water concrete mix also needs no extra damp-proofing, drawing on technology created for the original KOI Superior Walls precast concrete system.
- The advanced engineering and many innovative features of the Xi Wall foundation insulation make it the precast concrete foundation system of tomorrow—and the clear choice for discerning architects, builders, and home buyers.
