Superior Walls foundations are dry, using a special low water/cement ratio concrete that requires no additional dampproofing (See ESRs-1553 & 1662). They are warm, with full-length insulation built in to increase energy efficiency. Superior Walls high strength 5000+ psi concrete is reinforced with steel rebar and polypropylene fibers for added strength and performance. The wall panels also feature convenient features like built-in accesses for wiring and stud facings for easy drywall installation with screws. Another important feature for builders is the speed of installation. A typical home foundation can be installed in less than one day. The walls can then be built upon or a modular home may be set on the walls immediately after installation.
