Navigating Foundation Repair in Phoenix, AZ: A Detailed Guide


Being a homeowner in Phoenix, AZ, might bring with it concerns about your home’s structural foundation. The area’s desert climate, expansive clay soils, and temperature variations can all contribute to potential foundation issues. This comprehensive blog post will explore the realm of foundation repair in Phoenix, outlining the common causes, indicators of damage, remediation methods, and the necessity of engaging a reputable contractor.

Typical Causes of Foundation Issues in Phoenix, AZ

Expansive Clay Soils

Phoenix is notable for its expansive clay soils, which swell and shrink depending on moisture levels. When these soils soak up water, they exert upward pressure on the foundation, resulting in heaving and cracking. Alternatively, when the soil dries and contracts, it may leave voids beneath the foundation, causing uneven settling.

Temperature Variations

Significant temperature fluctuations are a characteristic of Phoenix, with its scorching summers and cooler winters. These temperature changes can lead to soil expansion and contraction around your foundation, resulting in progressive foundation movement and damage.

Insufficient Drainage

Poor drainage around your home can cause an accumulation of excess moisture in the soil, leading to expansion and subsequent pressure on your foundation. This can result in heaving, cracking, and other foundation issues.

Construction Challenges

Improper construction methods, such as insufficient soil compaction and poor foundation design, can contribute to foundation issues in Phoenix homes.

Identifying Signs of Foundation Damage

Wall and Ceiling Cracks

Cracks in walls, ceilings, and floors often serve as clear indicators of foundation issues. While minor hairline cracks are normal, larger cracks or a sudden proliferation of cracks may signal a foundation problem.

Uneven Flooring

If your floors appear uneven, it may indicate foundation settling or heaving.

Difficulty Opening Doors and Windows

A shifting foundation may misalign doors and windows, causing them to stick and become difficult to open and close.

Gaps between Walls and Ceilings

A moving foundation can lead to gaps forming between walls and ceilings, signaling structural movement within the home.

Foundation Repair Techniques


Underpinning, a common method of foundation repair, involves supplementing the existing foundation. This can be achieved using various techniques, such as:

Helical Piers: These are steel shafts with helical plates that are drilled into the ground to provide additional foundation support.

Push Piers: Also known as resistance piers, these are steel shafts driven into the ground and connected to the foundation, effectively transferring the home’s weight to more stable soil.

Slab Piers: These are utilized to support and elevate a concrete slab foundation, transferring the weight to more stable soil.


Mudjacking, also known as slabjacking, is a technique used to lift a sunken concrete slab by injecting a cementitious mixture underneath the slab, filling voids, and raising the slab to its original position.

Soil Stabilization

Soil stabilization methods, such as chemical injection or compaction grouting, can be used to enhance the soil’s load-bearing capacity, reducing the likelihood of future foundation issues.

Drainage Solutions

Implementing proper drainage systems, such as French drains, sump pumps, and gutters, can help prevent foundation problems by managing excess water around your home.

About Ram Jack

Ram Jack is a family-owned business that began operations in 1968, in Ada, OK, where we currently source our piers and brackets. Back then, concrete piering was the original repair method used simply because it was the only technology available at the time. Over time, it became evident that concrete piers did not provide long-term stabilization of foundations and only provided a short-term warranty period. To guarantee the highest grade of customer satisfaction, a greater solution needed to be found.

The Ram Jack owners embarked on a research program to develop a foundation repair system to stand the test of time. The U.S. Patent and Trademark Office first issued a patent to Ram Jack for its foundation repair system in 1985. Over the next few years, additional refinements and patents have followed, resulting in the strongest patented system in the industry. Ram Jack driven pilings are ICC-ES recognized (International Construction Code—Evaluation Services). Ram Jack is one of only two ICC-ES recognized foundation repair companies in the industry. Ram Jack’s products meet or exceed code requirements set down by ICC-ES for both commercial and residential properties.
