What Is a Helical Pier System?

A helical pier system is an engineered foundation repair method that uses screw-like steel piers to secure unstable or sinking foundations. The piers are mechanically advanced into the ground until they reach competent, load-bearing soil. Once installed, the structure’s weight is transferred to the piers, halting further settlement and in many cases, lifting the foundation back to its original position.

Helical piers are ideal for both new construction and existing foundations showing signs of settlement, and they are particularly effective in areas with difficult soil conditions or limited access for heavy equipment.

How Helical Pier Foundation Repair Works

1. Site Evaluation and Planning

Our team begins with a comprehensive inspection of your foundation to determine the extent of settlement and evaluate soil conditions. We then design a repair plan customized for your structure and soil profile.

2. Pier Installation

Helical piers are installed using specialized hydraulic equipment that rotates the piers into the ground like a giant screw. The helical blades pull the pier downward until it reaches a pre-determined torque that indicates stable soil.

3. Load Transfer and Stabilization

Once all piers are installed, steel foundation brackets are attached to the footing of your home or building. The weight is then transferred from the foundation to the piers. In many cases, the structure can be lifted to its original position.

4. Finalizing the Repair

After achieving the desired stabilization or lift, the system is permanently secured. Excavated areas are backfilled, and your property is restored with minimal disruption.

Benefits of Helical Pier Foundation Repair

• Immediate Load Capacity: Helical piers are ready to support weight as soon as they are installed, offering quick and effective stabilization.
• Ideal for Challenging Soil Conditions: Helical piers perform well in soft, loose, or expansive soils common throughout the St. Louis region.
• No Vibration or Disturbance: Unlike driven piers, installation causes minimal vibration, making it safe for fragile structures.
• Precise Installation: Torque monitoring ensures each pier reaches competent soil before load transfer begins.
• Minimal Excavation: Helical pier systems require only small excavation points, reducing damage to landscaping or hardscaping.
• Versatile Application: Suitable for residential, commercial, and industrial structures, as well as lighter buildings or those with variable loads.
• All-Weather Installation: Helical piers can be installed in nearly any weather condition, ensuring year-round service availability.
• Durable Materials: Constructed from high-strength galvanized steel for long-term performance and corrosion resistance.
• Lift Capable: In many situations, our system can lift a sunken foundation back to its original level.
• Ideal for New Construction Foundations: Helical piers provide a strong, stable foundation for new buildings, preventing future settlement and offering peace of mind from the start.

Technical Features of Helical Pier Systems

Helical piers are manufactured using high-strength tubular steel with helix-shaped plates welded to the shaft. These plates provide the "screw-in" action and help anchor the pier deep into stable soil. Key features include:

• Shafts: Typically 2 7/8" or larger in diameter, made of round or square shaft tubular steel with high yield and tensile strength.
• Helix Plates: 3/8" to 1/2" thick steel plates that vary in diameter depending on load requirements.
• Brackets: Heavy-duty foundation brackets attach the pier system to your home’s footing for secure load transfer.
• Corrosion Resistance: Many systems feature galvanized coatings for added durability in wet or chemically active soils.

Why Choose Helical Piers Over Other Foundation Solutions?

Helical pier systems offer a number of advantages compared to other foundation repair methods:

• Unlike push piers, helical piers do not rely on the structure’s weight to drive them into the soil, making them suitable for lighter buildings.
• They can be installed with smaller equipment and in tighter spaces, making them ideal for urban or limited-access sites.
• Installation is fast, clean, and precise.
