La Vergne Pier Systems

Pier systems are a fundamental tool recommended in structural engineering and utilized in foundation repair. They are primarily composed of steel shafts strategically placed deep into the earth near the foundation perimeter. This installation involves rigorous scientific calculations to ensure optimal placement and stability. These steel shafts are not standalone; they are affixed to the structure using high-grade metal brackets, creating a robust, reliable system.

The Importance of Pier Systems in Foundation Repair

Pier systems are critical in foundation repair due to their unique structural properties and deployment mechanics. These systems are designed to penetrate the ground until they encounter the point of refusal, or competent load- bearing soils. The term "competent" refers to soil layers that consistently withstand the load imposed and demonstrate the ability to bear and distribute weight effectively.

When the pier systems reach these competent strata, they act as load-distributing pillars. They manage the weight of the building, redistributing it from the compromised areas of the foundation to the stable, load-bearing soils. This function is crucial in alleviating stress on weakened parts of a structure's foundation and is fundamental to foundation repair. 

Types of Pier Systems

At United Structural Systems, we primarily rely on two types of pier systems: push and helical. Both are designed to cater to different foundation issues and soil types.

Push Piers

These unique pieces of technology are essentially hollow steel tubes. They are forcefully embedded into the earth using a hydraulic ram, a powerful piece of machinery that ensures the pier reaches the required depth. This depth is not arbitrary; the piers are pushed until they interact with the load-bearing soil strata, or point of refusal, promising a stable base.

But when is the ideal time to call upon these push piers? They are the go-to choice when dealing with a situation known as differential settlement. This occurs when different parts of a foundation settle at varying rates, leading to instability. Push piers provide a uniform lift, returning the structure to a balanced and secure state.

Helical Piers

Helical piers consist of steel rods equipped with helical blades resembling giant screws. With the assistance of hydraulic machinery, these piers are rotated and drilled into the earth.

Helical piers have a special role in the world of foundation repair. They are particularly effective in soil conditions that may restrict other stabilization methods. For example, helical piers provide a reliable solution when the soil is too loose or inconsistent. Another situation where they shine is when the structure is too light to generate the necessary force for push piers to penetrate to the required depth. In such cases, helical piers provide the adequate support needed for stability.

Our Approach to Implementing Pier Systems

Implementing pier systems is no simple task; it requires a systematic and thoughtful approach, which we at United Structural Systems have honed over years of experience. Our methodology revolves around careful assessment and tailored solutions.

Stabilizing a structure begins by thoroughly examining the property and surrounding environment. Each property comes with its own unique set of characteristics—the construction material, the architectural design, and the age of the structure—all of these factors play a part in our evaluation.

However, the focus of our evaluation is undoubtedly the soil. The nature and condition of the soil significantly influence the type of pier system we choose. The presence of clay, silt, sand, or rock; the level of soil compaction; and the depth at which stable, load-bearing soil can be found—all these aspects are closely studied.

This detailed assessment allows us to determine whether push or helical piers would be the most effective solution. Whether combating differential settlement with push piers or overcoming weak surface soils with helical piers, our team ensures the chosen solution is ideally suited to the conditions of your soil and the needs of your structure.

We pride ourselves on our ability to craft customized strategies to address the particularities of each foundation challenge. We approach every La Vergne pier system project with an open mind, a keen eye for detail, and a deep commitment to finding practical solutions.

The stability of your property should never be a matter of compromise. Secure your peace of mind and the structural integrity of your building with our services. Call (615) 307-9510 or submit an online contact form today.
