Customer FAQ
Can You Fit My Homeplan?
The walls are custom-designed and built to fit virtually any building type and architectural style, complete with window and door openings.
How Long Does The Process Take?
Factory-to-job site delivery promotes reliable scheduling, allowing projects to run more quickly and efficiently, with less waste and less down-time. A Superior Walls project can typically be installed in just hours, not weeks.
How's Superior Walls Different?
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.
What are Superior Walls?
Superior Walls of North Carolina offers patented, insulated, precast concrete wall panels created in a factory-controlled environment. These panels are delivered to the construction site, lifted into position with a crane, and securely bolted and sealed together. Custom-designed to fit nearly any architectural style, Superior Walls come with pre-formed openings for windows and doors.
What makes Superior Walls better than conventional foundations?
Superior Walls foundations are crafted using a special low water/cement ratio concrete, ensuring dryness without the need for additional damp proofing (US Markets; see ESR-1662). They feature full-length insulation for enhanced energy efficiency and are made with high-strength 5000+ psi concrete, reinforced with steel rebar and polypropylene fibers. Convenient built-in features include accesses for wiring and stud facings for easy drywall installation. Additionally, a typical home foundation can be installed in less than one day, allowing for immediate construction upon the walls. For more details, refer to our Code Officials page.
Why does Superior Walls use a crushed stone footing?
Superior Walls employs a crushed stone footing along with a steel-reinforced footer beam to distribute the wall’s load over a large soil area, preventing soil bearing capacity from being exceeded. This clean, crushed stone layer effectively transfers the load from our wall system to the soil. For more information, see the Builder Guideline Booklet (MAN 42-9000) and the Public Documents page.
How are Superior Walls panels joined together?
Superior Walls panels are bolted together at the top and bottom, with a one-part polyurethane sealant specifically made for precast concrete products used to seal the joints.
What is the R-value of a Superior Walls foundation?
Superior Walls of North Carolina offers the Xi wall system with 2-1/2″ of high-density foam insulation, providing an R-value of 16. Availability may vary, so please contact Superior Walls of North Carolina for more information.
What is the Superior Walls warranty?
Superior Walls products are manufactured and installed by independently owned and operated factories licensed by Superior Walls. We offer a limited warranty covering defects in workmanship, materials, and sidewall water penetration. Warranty terms may vary due to state and local regulations.
How is the depth of the crushed stone footing determined?
The depth of the crushed stone footing is based on the allowable soil bearing capacity and the combined footing load per lineal foot. This is detailed in the Builder Guideline Booklet. More information is available on the Public Documents page as well.
Where can I obtain design values for the Superior Walls panels?
The ICC Evaluation Service has produced an Evaluation Service Report (ESR-1662) for our Xi wall systems, available on the corporate website. The report contains design value information, including allowable loads and uses for the wall system. Visit our Code Officials page for more details.
What are the standard heights and lengths of Superior Walls panels?
Superior Walls of North Carolina custom-makes wall lengths determined by panel weight, crane reach, and foundation geometry. We offer 4’, 8’2”, 9’, 10’, and 12’ wall heights. Availability may vary, so please contact Superior Walls of North Carolina for more information.
How soon can the walls be backfilled after installation?
To meet building code requirements, the wall must be supported at both the top and bottom before backfilling. This includes completing the framing/decking connection at the top and installing the floor slab at the bottom. More details can be found in our Builder Guideline Booklet on the corporate Public Documents page.
What types of exterior finishes can be applied to a Superior Walls foundation?
Superior Walls panels come with a brushed finish that can be left as is or covered with finishes like paint, stucco, cultured/manufactured stone, or stone/brick veneer. Paint manufacturers typically recommend elastomeric acrylic paints for precast concrete. For stucco and stone, follow the manufacturer’s instructions, which may involve cleaning the panels and prepping the surface. Masonry screws and wire lath may be needed for joint spanning.
How do I attach drywall to my Superior Walls foundation?
After installing corner studs and blocking, the panels are ready for drywall. Use at least ½” drywall, leaving a ½” gap from the floor to avoid moisture absorption. Attach drywall with 1” screws and construction adhesive on the top bond beam and stud faces. More details are available on our Public Documents page.
Can additional insulation be added to a Superior Walls foundation?
Yes, additional insulation can be added. We recommend closed cell insulation products like high-density foam to prevent moisture issues. Closed cell insulation keeps moisture from reaching the cooler wall surface and condensing. More details can be found under “Adding Insulation” on our Public Documents page.
Where can I find information about finishing my basement?
The Superior Walls “Homeowner’s Guide,” available on the corporate website, provides helpful information about finishing your basement. Additional “How to” documents on insulation, drywall blocking, and more are available in our Documents Center. For comprehensive guidance, refer to our Builder Guideline Booklet on the Public Documents page.
Can I add a window or door to an existing Superior Walls foundation?
Yes, you can add a window or door after evaluating factors like point loads and frost protection. Consult your Superior Walls of North Carolina sales rep and an engineer or competent structural designer for guidance. More details are available in the “Tech Resources” section on the Public Documents page.
Can Superior Walls Panels be used for more than basement foundations?
Yes, Superior Walls of North Carolina offers both the Xi and AG (Above Grade) Wall Systems. These systems can be combined for complete multi-story systems. For more information, explore our product offerings and their applications.
