The second type of concrete foundation, a post-tension foundation, also falls within the family of monolithic foundations but also contains an inner tension created after the concrete is poured – which is why it is called post-tension, or “after-tension.” A regular monolithic foundation probably contains a rebar inside only the perimeter. In contrast, a post-tension foundation contains a horizontal grid pattern of steel reinforcement cable with a protective covering throughout the inside of the slab. The steel cable becomes tense as the concrete warms, allowing the foundation to maintain shape with less cracking. The result is a strong foundation that allows some flexibility in its shape. This is particularly useful in places like Arizona, where the soils are prone to move, shift, or expand under concrete foundations. Unfortunately, over time, rebar reinforcement is subject to invading moisture from the exterior that can cause oxidation and wearing of the foundation material. Arizona’s homeowners can stop these destructive effects with a full repair, waterproofing, and painting method provided only by seasoned expert James Belville and Concrete Repairman LLC.

Stem Wall Foundation

Stem wall foundations are the least expensive of the foundation types and the least structurally stable solution you’ll find in Arizona. A stem wall foundation is, by definition, not monolithic and not made up of a single continuous piece. Stem wall foundations rely on an underlying pattern of short, upright walls – both around the perimeter of the foundation and along the lengths of interior room walls. These upright walls protrude slightly above the surface and support a flooring layer. A common and dangerous problem in stem wall foundations is the formation of horizontal cracks along the foundation, usually above the ground. This visible cracking often occurs because moisture invades beneath the paint’s surface, rises toward the steel, and begins to cause oxidation. This rust and corrosion deteriorates the concrete around it, leading to cracking, crumbling, and structural instability.

Until their residential or commercial foundation begins to deteriorate or fail, the characteristics of concrete foundations will remain mysterious to most home and property owners. It is common for a company to make foundation repairs without going very far beneath the surface, where the problem starts. James Belville knows that most repair companies and contractors often neglect to go deep enough, fail to create a lasting seal, and rarely repaint the surface of a repair. With a better understanding of their foundation type, homeowners and other property owners can take the correct steps for repairs and maintenance.
