Foundation problems such as settling or sinking foundations tend to worsen over time. For this reason, you should repair such problems as soon as you notice them. This is where the helical pier system could come in handy. Consisting of a central shaft with one or more helix-shaped plates, which are also known as flights or blades, helical piers are essentially a ground anchoring system.

Helical piers are also known by a variety of other names including helix anchors, helix piers, helical anchors, screw piles, and helical piles. It is worth noting that the terms “pier” and “anchor” are generally used to refer to helical piles loaded in axial compression and axial tension, respectively. For both retrofit applications and new construction project, contractors typically use brackets to attach the top of the helical piers to structures. What’s more, if need be, contractors may use extension shafts with additional helix flights to extend helical pier systems to competent weight-bearing soil and achieve the desired settlement.

How Do We Install Helical Piers?

Building contractors use a hydraulic torque motor to screw/install helical piers into the ground. However, because helical pier systems are self-auguring, the installation process is typically gentle and vibration free. What’s more, these systems can even be installed in tight spaces, thanks to the maneuverability and relatively small size of the installation equipment.

Where Can We Use Helical Piers?

Developed over 150 years ago, the helical pier system is a tested and proven technology. This anchoring system can successfully support structures in almost all soil types. Besides foundation anchoring, helical pier systems can be used for Deadman anchoring, fixture anchoring, seismic protection, and tieback anchoring.

What Are the Benefits of Helical Piers?

Helical pier systems offer several benefits. For starters, they place no mechanical stress upon the foundation during the installation process. Secondly, they can be installed even in tight spaces. Thirdly, they can be installed inside or outside a building. Fourthly, the installation process is fast, efficient and environmentally friendly.

Helical pier systems are used to stabilize and protect existing foundations from structural damage, as well as secure new foundations. Common foundation problems include settling/sinking foundation and cracked wall or floor. In addition, they can be used for fixture anchoring, Deadman anchoring, and seismic protection, among other things. Helical pier systems are generally easy to install, can be installed in any weather condition and require minimal excavation. What’s more, they can be used in virtually any type of soil.
