Concrete / Lawrence
What is moving beneath the slab?
A raised sidewalk edge and a sloping floor inside a home are different concerns. The location of the movement changes the questions.

Flatwork or foundation?
A walkway can settle as support below it changes. A crack in a home’s structural slab needs a different level of scrutiny, particularly when doors or walls are changing too. Photograph the edge and the surrounding area, not just the crack.
Lawrence-area clay may swell after rain and shrink in a dry spell. Drainage can also move material beneath concrete. Neither possibility should be treated as a diagnosis without seeing the slab and nearby ground.

Lift, patch, or investigate further?
Leveling settled concrete
Some sound slabs can be lifted by adding material beneath them. Ask whether drainage could cause the problem to return.
Repairing a stable crack
A patch can address a surface opening; it cannot correct a continuing loss of support below the concrete.
Assessing a house slab
If indoor floors, walls, and openings are also changing, seek a broader foundation inspection.
Questions to bring
Ask about the result, not just the method.
Will the repaired surface direct water away from the home? Is the slab sound enough to lift? What change should you expect afterward? A written scope should describe the area, method, and restoration.
If water collects nearby, review our basement and drainage guide. For budgeting questions, use the repair cost guide as a checklist rather than a quote.
Slab FAQ
Before a repair.
Can you fix a foundation yourself?
You may be able to maintain a small, stable surface crack. A house slab that is moving, or a crack with height difference and recurring water, needs a professional assessment before patching.
Is leveling a walkway foundation repair?
Not usually. Outdoor flatwork and a structural slab have different roles. Ask the professional to identify which is affected.
