Helical Piers: Stabilizing Settling Foundations From The Soil Up

Both are steel piers that stabilize a foundation by transferring its weight onto deeper, stable soil, but they get there differently. A helical pier is screwed into the ground with hydraulic torque, much like a large screw, and the installation torque tells the crew when it has reached load-bearing soil. A push pier is hydraulically driven straight down using the weight of the structure itself as resistance. Helical piers are often well suited to lighter structures and to situations where the soil conditions favor a screwed pier. During your inspection we explain which system fits your foundation and why.

Often, yes, at least partially. Once the piers are installed and bearing on stable soil, we can in many cases use them to raise the foundation back toward its original elevation, which frequently helps close settlement cracks and bring doors and windows back into alignment. How much lift is realistic depends on the specific structure, how long it has been settling, and the soil involved. We set honest expectations about achievable lift during the inspection rather than promising a full correction sight unseen.

It usually comes back to the soil beneath the footing. In the Piedmont around Charlotte, Greensboro, Winston-Salem, and the Triangle, clay-rich soils swell when they take on water in wet seasons and shrink as they dry out, and that repeated movement can leave a footing without consistent support. In the Asheville area and the mountains, sloped lots and heavy rainfall can move water through hillside soils and undermine the ground beneath a foundation. Poorly compacted fill soil under part of a home is another common contributor. Helical piers address settlement by reaching past that active surface soil to firmer ground below.

Helical piers are a permanent structural solution. They are made of steel and bear on deep, stable soil that does not move with the seasons the way shallow surface soil does, so once the load is transferred the foundation is supported for the long term. The honest qualifier is that piers address the structural support beneath the home and not surface drainage or moisture, so where water management is part of the picture we address that separately to protect the overall repair.

Cost depends on the number of piers your foundation requires, how deep they must go to reach load-bearing soil, access to the affected areas, and the soil conditions involved. Because those factors vary from one home to the next, we provide pricing after a no-pressure inspection rather than a flat number online. The inspection is how we give you an accurate, honest quote for your specific situation.

Installation involves excavating small access areas at each pier location along the affected section of foundation so the brackets can attach to the footing. It is a focused operation rather than a tear-out of your foundation, and much of the work happens below grade. We backfill and restore the access areas once the piers are in place, and during the inspection we walk you through what to expect for your specific project.
