Helical Piers: A Smarter Solution for Lasting Foundation Support

When soil conditions shift or traditional foundations start to fail, structural stability becomes a serious concern. That’s where helical piers come in. Engineered to provide deep, reliable support for everything from residential homes to boardwalks, retaining walls, and commercial buildings.

At Pinnacle Structural Services, we use helical pier systems to address foundation settlement and support new construction in a wide range of soil conditions across the Denver metro area. Whether you’re stabilizing a sinking foundation or building on unpredictable terrain, helical piers offer strength, precision, and flexibility unmatched by traditional foundation methods.

What Are Helical Piers?

Helical piers, also known as screw piles or helical anchors, are steel foundation elements designed to be advanced into the ground like giant screws. Their unique design features helical plates, or “blades,” welded along a central shaft. These plates allow the pier to be rotated into the soil with minimal disturbance, generating both tension and compression support once installed.

Because of their simplicity and load-bearing strength, helical piers are ideal for both foundation repair and new construction. They are particularly effective in areas with soft, shifting, or expansive soils. These are conditions frequently found across Colorado.

Key Components of a Helical Pier System

A standard helical pier assembly includes:

• Lead Section: The initial segment that contains one or more helixes for anchoring into soil.
• Extension Shafts: Additional steel segments that increase the pier’s depth to reach stable load-bearing strata.
• Brackets: Custom structural connectors used to secure the pier to the foundation—either underneath a footing or directly to a structure’s frame.
• Helical Plates: Circular steel discs that engage the soil and generate resistance as the pier is turned in.

Materials are typically high-strength galvanized or coated steel, offering long-term corrosion resistance and durability.

How Helical Piers Work

The strength of a helical pier lies in its ability to transfer a structure’s load through unstable or weak soil and into deeper, load-bearing layers. As each helix rotates into place, it pulls the shaft downward and disperses weight across a wider area than a straight shaft alone could achieve.

This method offers precise torque-to-capacity correlation, allowing contractors to verify each pier’s load resistance during installation. That means no guesswork. You know the system is secure the moment it’s installed.

Benefits of Using Helical Piers for Foundation Support

Quick, Low-Impact Installation

Unlike driven piles or drilled concrete piers, helical piers don’t require heavy excavation or vibration-inducing machinery. They can be installed using compact equipment, making them perfect for tight access areas or active job sites.

Strong Support in Poor Soil

Helical piers perform exceptionally well in expansive clay, sandy soils, or areas with high water tables. These conditions are common throughout the Front Range.

Long-Term Durability

Engineered for strength and corrosion resistance, helical systems are built to last for decades without significant maintenance.

Minimal Disturbance

With no spoils, no concrete curing time, and no large staging area needed, the installation process is fast, clean, and environmentally low-impact.

Versatility

Helical piers can be used to stabilize existing foundations suffering from settlement, or as primary deep foundations for new structures large or small.

When to Use Helical Piers

Helical piers are effective in a wide range of structural applications. Here’s where they shine:

Foundation Settlement & Structural Stabilization

If your home or building is showing signs of foundation movement: cracked walls, sloping floors, sticking doors, helical piers offer a fast and reliable method to halt and often reverse settlement. They are installed adjacent to existing footings and then hydraulically lifted to re-level the structure.

New Construction on Unstable Soils

Building on expansive clay, loose fill, or wet ground? Helical piers provide a solid base for decks, additions, sunrooms, and even full structures without waiting for concrete to cure or soil to settle.

Retaining Walls and Slope Reinforcement

In hillside or erosion-prone areas, helical tieback anchors can be used to reinforce retaining walls or stabilize soil. These anchors resist lateral movement and prevent costly slope failures.

Elevated Structures and Boardwalks

For projects requiring minimal ground disturbance like boardwalks, viewing platforms, or pedestrian bridges, helical piers provide both structural support and environmental sensitivity.
