Precast concrete foundation walls - which company?
I'm building a house in western NC with Deltec homes which builds a round house using panelized construction. Deltec recomended using a precast foundation which matches their construction method of building wall panels in a factory. Superior Walls was recommended by Deltec. I've since found another company, Ideal Foundations. Both erect insulated concrete panels over a crushed stone foundation. Another company, International Precast of Siler City, NC, offers insulated concrete panels that are secured to concrete footings. My mountain lot is moderately sloped. Anyone have experience with precast foundations from these companies?
