What are the components of the Superior Walls System?

Superior Walls panels are created in a factory, where high-strength 5,000+ psi concrete is bonded directly to DOW® insulation. Solid concrete studs provide support, as does a built-in concrete footer that rests on a sub-footer of clean crushed stone. The attention to detail is evident in features that make finishing basements easy, such as pre-engineered wiring access holes and furring strips for easy drywall installation.

How does the strength of the Superior Walls System compare to the strength of a block wall?

A 5,000 psi concrete wall combined with top and bottom bond beam and solid concrete studs reinforced with rebar, means our Superior Walls system is about ten times stronger than a conventional block wall.

Why isn't a concrete footer used with Superior Walls Basement System?

Many people are under the mistaken impression that a concrete footer is what keeps your house from settling. Actually, the primary purpose of a concrete footer is to provide a level, solid area on which to start laying block. Water can be trapped under a footer or slab, allowing hydrostatic pressure to build up and actually cause settling or heaving. The gravel footer system, promoted by architect Frank Lloyd Wright, allows water to drain away from the basement slab and wall system. A site that is properly drained will not have any water or noticeable settling problems.

What is the insulation value of the walls?

Superior Walls offers two wall systems. The Xi wall system is built with a continuous layer of 2.5" Styrofoam, resulting in an R-value of 12.5. The Xi Plus wall system offers an R-value of 21.3.

What makes Superior Walls better than conventional foundations?

Superior Walls foundations are dry. By using a special low water/cement- ratio concrete, our wall system requires no additional damp proofing. They are warm, with full-length insulation built in to increase energy efficiency. Superior Walls high-strength 5,000 psi minimum concrete is reinforced with steel rebar and polypropylene fibers for added strength. They are smart, with convenient features like built-in accesses for wiring and treated wood nailers for drywall. An important feature for builders is the speed of installation. It takes just five hours to install a typical home foundation.

How are Superior Walls delivered and installed?

After manufacture in a factory-controlled environment, Superior Walls panels are delivered to the new home job site on special carriers. There, cranes carefully lower the custom walls onto a bed of clean crushed stone, where they are permanently installed into place by specially trained crews. A triple bead of Superior Sealant forms a tight permanent seal against moisture. As soon as the foundation is in place, building can begin immediately - usually the same afternoon.

Who is responsible for preparing our site for installation of the foundation system?

It is your responsibility to prepare the set site prior to the delivery of your foundation. The site must meet the guidelines listed in our "Site Preparation Manual." Upon initial down payment you'll receive easy-to-follow, fully illustrated manuals that include everything you need to know about preparing your site for our crews.

Is it necessary to parge or tar the wall after installation?

No! The Superior Walls basement system is made with 5,000 psi concrete. According to the American Concrete Institute, 4,000 psi mix is watertight.

A lot has been published about the dangers of radon. Does Superior Walls have a position on protection from radon?

Radon gas is a natural byproduct of depleted and disintegrating uranium. It's a radioactive heavy gaseous element that cannot be seen, tasted or smelled. Because the pressure in a dwelling is usually less than in the soil, radon can be drawn from deep within the earth into a home through foundation cracks or other openings. The surgeon general has warned that radon is second only to smoking as a leading cause of lung cancer in the United States today. Proper building techniques can minimize the possibility of radon entering your home. The PA Department of Environment Resources urges the builders of new homes to put a radon venting system in place during the construction process. Building codes regarding radon vary from area to area, so be sure to discuss these issues with your local code enforcement officer.

Where can homeowners and builders find Superior Walls?

All over the country. There are 20 Superior Walls franchises in 14 states. Foundations have been installed in over 30 states, protecting against everything from cold New England winters to hot summers in Florida. Superior Walls of America is headquartered in New Holland, Pennsylvania.

What is "Lower Level Living Space?

Lower Level Living Space is a term that refers to the additional marketable square footage in a home that is achieved by a combination of 8% natural light and 4% ventilation in the basement, or lower level of the home. This can be accomplished by using Superior Walls with the Boman-Kemp Egress Window System.

What are Boman-Kemp Egress Windows?

Boman-Kemp Egress Window Systems installed in Superior Walls meet Lower Level Living requirements and include stainless steel window frames to protect against corrosion, white vinyl windows with insulated glass, a white finish on galvanized area wells to reflect additional light, emergency escape ladders, metal safety grates and clear lexan covers

How do Superior Walls perform relative to the 2003 IRC Code?

The new IRC code includes new regulations on basement insulation requirements with increased R-values in the range of R-8 to R-11, depending on region. Whereas all foundation systems will require additional on-site insulation, Superior Walls is the only foundation system that does not require additional framing to accommodate the extra insulation. The extra insulation is simply installed between the existing wall cavities. Plus, the original R-5 Superior Walls system needs less extra insulation than traditional block or poured foundations to meet the new code requirements. The new Superior Walls Xi Wall (Xi stands for "extra insulation") offers an R-value of 12.5 built right in, and does not require the installation of additional on-site insulation.
