Signs of a Slab Foundation Problem
A slab sits directly on the ground, so soil movement shows up quickly in the floors and walls above it. Homeowners in the Baton Rouge area commonly notice these signs.
- Cracks in the slab, or in tile and flooring above it
- Doors that rub or will not latch
- Floors that slope toward one side of the house
- Diagonal cracks running from the corners of doors and windows
- Gaps between the slab and the exterior walls or brick
- Garage floor cracks that keep growing
How Slab Foundation Repair Works
Why not wait?
Small movement rarely stays small. As the soil keeps shifting, cracks widen, doors bind and the plumbing under the slab can be stressed, which can turn a modest repair into a bigger one.
Slab repair starts with finding out why the slab moved. In clay-rich soil the cause is often moisture: the soil under one part of the house swells or shrinks and the slab follows. Plumbing leaks under the slab, poor drainage and large trees that pull water from the soil are other common causes.
Common repair methods
Piers or piles. Steel or concrete supports are driven or placed down to more stable soil and used to lift and hold the slab. This is a common answer when a section of the slab has settled.
Slab lifting. A material is injected under the slab to raise a low area. It is used more often for patios, driveways and garage floors than for the main house slab.
Crack sealing. Epoxy or polyurethane injection keeps water out of cracks, but it does not stop the movement that caused them.
Fixing the cause. Repairing a leak or changing how water drains can keep the soil from moving again.
The right method depends on the inspection. Ask the contractor why they recommend it and what the warranty covers.

Repair and follow-up
The work is done and the contractor rechecks floor levels and cracks.
Slab Foundations in the Baton Rouge Area
Many newer homes around Baton Rouge are built on slabs. Heavy rain followed by dry heat makes clay-rich soil swell and shrink, and a slab sits right on top of that movement.
Drainage matters as much as the repair. If water collects beside the slab, the problem can come back. Because the slab covers the plumbing lines, ask the contractor how they will check for leaks.
Slab Foundation Repair Questions
Still not sure? Describe your situation in the quote form and a local contractor can answer questions about your house.
How do I know if my slab has settled?
Look for sloping floors, sticking doors, diagonal cracks near door and window corners, and gaps along exterior walls. A contractor can measure floor elevation to confirm.
Are slab cracks always serious?
No. Small hairline cracks are common as concrete cures. Cracks that widen, run through tile or come with sloping floors deserve an inspection.
Can a slab be raised back to level?
Often a settled area can be lifted with piers or injection. How much can be recovered depends on the house and the cause.
How long does slab foundation repair take?
Smaller repairs can take a few days and larger projects take longer. Ask the contractor for a timeline with the estimate.
Should I fix drainage as well?
In many cases yes. Water that keeps collecting near the slab can cause new movement, so drainage is often part of the plan.
