Most people will never try to understand the physical components of a structure that lie below a home’s flooring. If and when the time comes for a foundation repair, understanding your foundation type and characteristics will lead to the best service and solutions. Contractors build homes in Arizona using three different kinds of concrete foundations: monolithic, post-tension (a type of monolithic) and stem wall foundations.

Monolithic Post Tension Foundations

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, while a post-tension foundation contains a horizontal grid pattern of steel reinforcement throughout the slab. The steel bars become tense as the concrete cools, 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 that can cause oxidation and wearing of the foundation material. Arizona’s homeowners can stop these destructive effects with a full repair, sealing, and painting method provided only by seasoned expert James Belville and Concrete Repairman LLC.

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.

FAQs About Post-Tension Foundations

A post-tension foundation is a reinforced concrete slab that uses high-strength steel cables (tendons) to provide additional structural integrity. After the concrete is poured and cured, the wires are tensioned using a hydraulic stressing jack, which compresses the slab and increases its resistance to cracking, soil movement, and settlement.

Traditional slabs use rebar reinforcement, while post-tension foundations incorporate tensioned steel cables anchored within the concrete. The tensioning process places the slab in compression, allowing it to handle better expansive clay soil movement common in regions like Arizona.

Arizona’s expansive clay soils are prone to swelling and shrinking, which can cause cracks in conventional foundations. Post-tension systems are engineered to resist these soil pressures by maintaining uniform stress across the concrete slab, making them ideal for the state’s unique soil conditions.

Warning signs include visible cracks in floors or walls, uneven slabs, broken cable ends protruding, or unexplained settling. If any of these occur, homeowners should contact a qualified foundation repair specialist for a post-tension inspection.

Yes. Damaged or corroded post-tension cables (tendons) can be safely replaced by trained professionals using proper stressing and anchorage techniques. It’s critical to avoid cutting into the slab without identifying cable locations, as this can cause severe structural and safety issues.

Experts recommend an inspection every 2–3 years, or immediately if cracks, lifting, or settling appear. Regular inspections help detect corrosion, cable tension loss, or anchor movement before they compromise the foundation’s stability.

No,  drilling or coring through a post-tension slab without verifying cable locations can be extremely dangerous. Cutting a live cable under tension can cause injury and significant structural damage. Always use X-ray or ground-penetrating radar (GPR) before any slab modification.

When properly installed and maintained, post-tension slabs can last 50 years or more. Longevity depends on soil stability, moisture control, and regular inspection of cables and anchor points to prevent corrosion or tension loss.

Homeowners should maintain consistent moisture levels around the foundation, monitor for cracks, and ensure proper drainage away from the structure. Regular inspections by a foundation repair contractor can identify early signs of wear or soil movement.
