If your slab-foundation home in Montgomery is showing the classic warning signs — diagonal cracks above doorways, gaps between baseboards and the floor, doors and windows that have started to stick — your slab is moving. The question is how far it’s gone, what’s causing it, and what the right fix is.
Why Slab Foundations Fail in Montgomery
The newer subdivisions east of I-65 — Halcyon, Sturbridge, Wynlakes, and out into Pike Road — were almost all built on concrete slab. So were most of the homes around Maxwell AFB and through Eastdale. When these neighborhoods were developed, the topsoil was scraped, the building pad was prepared, and the slab was poured directly onto the underlying Black Belt clay.
That clay is the problem. Black Belt soil — technically called Vertisol — has an extraordinary capacity to absorb water. When it’s wet, it swells. When it dries out, it shrinks and cracks. Over a year in central Alabama, with our wet winters, dry summers, and unpredictable hurricane seasons, the clay under your slab moves up and down by an inch or more in some locations. The slab can’t move with it indefinitely. Eventually it cracks, and the cracks propagate upward into the framing of your home.
You can sometimes see this happening before the slab itself cracks visibly. Common early signs in Montgomery homes:
- Diagonal cracks at upper corners of doorways — the most reliable early warning
- Cracks running from the corners of windows — especially over garage doors
- Sticking doors and windows that worked fine a year ago
- Gaps appearing between crown molding and ceiling, or between baseboard and floor
- Cracks in the brick veneer, especially stair-step cracks following the mortar lines
- Cracks in the slab itself, visible if you have unfinished garage flooring or removed carpet
What We Do About It
The standard repair for slab settlement in Montgomery is underpinning with steel piers. We use two main types depending on your specific situation:
Steel push piers are hydraulically driven sections of high-strength steel pipe that we push down through the unstable clay until they reach load-bearing strata — typically 18 to 30 feet down in our area. The weight of your home then transfers through the piers to that stable layer, bypassing the expansive clay entirely.
Helical piers are steel shafts with helical plates that screw down into the soil. We use these when push piers aren’t ideal — for lighter loads, for porches and additions, or when soil conditions make pushing difficult.
In either case, the installation typically takes two to four days for a typical Montgomery home, and we can usually lift your home back to or near its original elevation while we’re at it.
Getting It Done Without Disrupting Your Life
We work around the perimeter of your home, which means most of your interior stays untouched. We dig small access holes (about 3 feet by 3 feet) at each pier location, drive the piers, attach the brackets to your foundation, and then back-fill and restore landscaping. Your home stays occupied throughout the work in almost every case.
We’ve done this work on homes in every part of Montgomery — from quiet streets off the Atlanta Highway to busy locations near Eastern Boulevard. We can work around your schedule.
Lifetime Transferable Warranty
The piers themselves are warrantied for the life of the home, transferable to future owners. This matters in Montgomery’s real estate market — when you sell, having a documented foundation repair with a transferable warranty is often the difference between a smooth closing and a painful renegotiation.
