What Is Foundation Pier Underpinning?
Foundation pier underpinning is the permanent solution for a settling or sinking foundation. When soft or unstable soil beneath a home can no longer support the structure's weight, piers are driven or screwed deep into the earth — past the weak soil — until they reach stable, load-bearing ground. The foundation is then transferred onto these piers, stopping further movement and in many cases allowing the foundation to be lifted back toward its original position.
Grand Rapids sits on glacial till soils that can include clay, sand, and fill material of varying density. Homes built on sections of poor fill, in low-lying areas of Kentwood or Wyoming, or near the Grand River floodplain are particularly susceptible to differential settling. Pier underpinning addresses the root cause — inadequate soil bearing capacity — rather than just patching the symptoms.

Push Piers vs. Helical Piers — Which Is Right for Your Home?
Push piers (also called resistance piers or steel push piers) are hydraulically driven straight down through unstable soil until they meet firm bearing strata. They're the most common solution for Grand Rapids area homes experiencing settling due to weak or compressible soil. The hydraulic driving process provides a built-in load test — the pier stops when it reaches soil capable of supporting the structure. Push piers are installed entirely from the interior of the basement in most cases, with minimal disruption to landscaping.
Helical piers are screwed into the ground using a hydraulic torque motor. They're better suited for new construction, lightly loaded structures, or situations where driving piers would cause vibration issues. Helical piers are also used for stabilizing decks, additions, and porches. The torque reading during installation correlates directly to load capacity, providing real-time verification that each pier is properly rated for the load it will carry.

Differential settling — where sections of a foundation sink at different rates — produces a distinctive set of symptoms throughout the home. Doors and windows that previously worked perfectly begin sticking, catching, or no longer closing fully. Diagonal cracks appear at the corners of windows and door frames, often in a stair-step pattern. Floors develop noticeable slopes or feel bouncy in areas. In the basement, you may see gaps forming between the wall and floor slab, or visible separation between the foundation wall and the structure above.
These symptoms typically worsen over time as settling continues. Grand Rapids freeze-thaw cycles and seasonal moisture changes in clay soils cause ongoing movement in already-compromised foundations. The earlier pier underpinning is installed, the less damage accumulates — and the more likely the foundation can be partially lifted back to its original position. A home with 1" of settling can often be fully recovered; a home with 4" of settling may be stabilized but not fully lifted.
