Foundation Settlement Repair in Montgomery, AL

Foundation settlement is the gradual sinking of a home’s foundation into the soil. In

Montgomery, Alabama, settlement is almost always caused by the region’s expansive clay,

which contracts during dry spells and loses its ability to support weight. Foundation settlement

repair in Montgomery involves stopping the movement and then lifting the foundation back to

its original position using engineered piers.

Active Settlement vs. Past Settlement

Not all settlement requires immediate repair. “Past settlement” occurs when the foundation

moved years ago and has since stabilized. In these cases, cosmetic crack repair may be all

that is needed. “Active settlement” means the foundation is still moving, typically at a rate of

1/8 inch per year or more. Signs of active settlement include cracks that grow wider over time,

fresh gaps between walls and ceilings, and doors that bind in summer but close easily in winter

(or vice versa). Montgomery Foundation Repair Co uses crack monitors and repeated level

surveys to determine whether your home is still moving before recommending repair.

The Role of Expansive Clay in Montgomery Settlement

Montgomery County’s red clay, part of the Sumter and Vaiden soil series, is highly expansive.

When dry, it shrinks and creates voids beneath the foundation. When wet, it swells and pushes

upward. This cycle of contraction and expansion is called “shrink‑swell” behavior. Over years

of repeated cycles, the soil structure breaks down, and the foundation settles deeper into the

ground. Unlike sandy soils that drain quickly, clay holds water for weeks, prolonging the

unstable period. Montgomery Foundation Repair Co designs repairs that bypass this

problematic layer entirely, anchoring your home to deep, stable strata where moisture changes

have no effect.

Repair Methods for Settled Foundations

The standard repair for active settlement is deep foundation underpinning with steel push piers

or helical piers. Piers are installed around the perimeter (and often interior for slab homes) to

transfer the building’s load to competent bearing strata. After all piers are in place, hydraulic

jacks lift the foundation back to its original elevation, usually within 1/2 inch of level. For homes

with minor settlement (less than 1 inch) that has stabilized, polyurethane foam injection may be

used to fill voids and provide shallow support. However, Montgomery Foundation Repair Co

always prioritizes pier underpinning when there is any evidence of ongoing movement.

What Happens If You Ignore Foundation Settlement

Delaying foundation settlement repair is never a money‑saving strategy. As the foundation

continues to sink, cracks in brick veneer widen, allowing water intrusion that damages interior

finishes. Plumbing lines can rupture where they enter the foundation, leading to slab leaks or

sewer backups. Floor tiles crack, hardwood floors gap, and drywall seams become visible.

Eventually, the foundation may settle so unevenly that the home becomes unsafe to occupy. At

that point, repair costs can double or triple, and some lenders may refuse to finance a home

purchase until repairs are completed. Montgomery Foundation Repair Co strongly

recommends addressing settlement as soon as it is detected.
