Why slabs move
- Plumbing leaks under the slab that wash out or saturate soil
- Tree roots that dry the soil near the house
- Expansive clay that swells when wet and shrinks when dry
- Original construction issues such as poor compaction or fill
- Poor drainage and grading that send water toward the foundation
Signs specific to slabs
- Floors that slope or feel hollow
- Doors that rub in the frame or no longer close
- Wet spots or high water bills that suggest a slab leak
- Cracked floor tiles and gaps at baseboards
- Exterior brick cracks near corners and doors
Slab repair methods compared
| Method | How it works | Notes |
|---|---|---|
| Drainage and moisture control | Grading, gutters, drains and watering practices | Reduces future movement. |
| Polyurethane foam | Foam injected under the slab to fill voids and lift | Minimal disruption for some cases. |
| Helical piers | Steel shafts screwed to load-bearing depth | Used where access or soil suits. |
| Pressed or drilled piers | Piers placed under the footing down to stable soil, then the slab is lifted | Common for settlement. |
| Mudjacking | A cement-based slurry is pumped to lift the slab | Used for light settlement and flatwork. |
Slab leak testing
Whether a supply line is leaking under the slab can be shown by a plumbing pressure test or acoustic leak detection. Movement can remain if a leak is fixed without addressing the soil, so the plumbing and the foundation are assessed together.
How a foundation visit works, step by step
A sound foundation assessment is evidence first and a repair proposal second. Knowing the order helps you tell a diagnosis from a sales pitch.
- Interview: when you noticed the problem, what changed (drought, rain, plumbing leaks, remodeling) and where it shows.
- Exterior walk: cracks, gaps at windows and doors, brick and stucco condition, grading, gutters, downspouts, trees near the house.
- Interior check: sticking doors and windows, floor slopes, drywall cracks, gaps at trim and ceilings.
- Measurements: floor elevations with a manometer or laser, crack widths and patterns, photos with a scale.
- Cause: soil moisture, drainage, plumbing leaks, tree roots or construction issues, and which ones apply.
- Written findings: what is cosmetic, what is structural, what to monitor and what to repair, in order.
Questions to ask a foundation repair company
- What did you measure, and what do the numbers say?
- What happens to landscaping, utilities and flooring during the work?
- Is the repair engineered, and can I see the design?
- What caused the movement, and how will you address the cause?
- How will you verify the result?
Mistakes that make foundation problems worse
- Planting large trees too close to the foundation.
- Over-watering or letting soil dry out completely around a slab in clay soils.
- Choosing a repair before getting measurements and a cause.
- Repairing cracks cosmetically without finding the cause.
- Ignoring drainage. Water at the foundation is the most common driver of movement.
What shapes the written scope
Two foundation jobs on the same street can differ widely. The written scope should say what was found and which of these applied.
- How much the structure has moved and where, from elevation readings
- The foundation type: slab-on-grade, post-tension slab, pier and beam, basement or crawl space
- Access for equipment, utilities and landscaping, and any permit or engineer requirements
- Drainage, grading, gutters and plumbing leaks that feed the problem
- The soil, especially expansive clay, and how wet or dry it has been
Prepare your Omaha home for the assessment
- Gather any earlier inspection reports, repair invoices and the home's construction year
- Take dated photos of cracks with a coin or ruler for scale
- Look for leaks, wet spots and unusual water bills
- Check gutters and downspouts and see where water goes near the foundation
- Note when doors started sticking and when cracks appeared
Safety and when an engineer should be involved
Independent of anyone selling a repair, a structural engineer can evaluate movement and design the repair, and an engineer's report is useful for a sale, an insurance claim or a large repair. Keep out of a crawl space or basement with standing water or visible structural distress, and think about utility lines before any digging.
Foundation terms explained
- Elevation survey: measurements of floor heights to show movement
- Hydrostatic pressure: pressure from water in saturated soil
- Slab-on-grade: a concrete slab poured directly on the ground
- Differential settlement: uneven movement of one part of a foundation relative to another
- Pier: a column placed deep under the foundation to carry load on stable soil
- Underpinning: strengthening or deepening an existing foundation
- Pier and beam: a foundation of piers and wood beams with a crawl space
- Expansive clay: soil that swells when wet and shrinks when dry
Myths and facts
- Myth: all cracks mean a failing foundation. Fact: many cracks are cosmetic.
- Myth: you can skip an engineer. Fact: an independent opinion is useful for big repairs.
- Myth: foundation problems come only from old age. Fact: water and soil are the main drivers.
- Myth: a repair means the house will never move again. Fact: soil still changes, so drainage and monitoring matter.
- Myth: bigger piers are always better. Fact: the design depends on the load and the soil.
A checklist for this week
- Look for plumbing leaks and unusual water bills
- Gather inspection and repair records
- Check doors and windows for sticking
- Check that downspouts discharge several feet away
- Walk the outside of the house and photograph cracks with a coin for scale
- Look for ponding or soil pulling away from the foundation
What makes foundation work different in Omaha
Omaha has older brick and block foundations, finished basements and clay and loess soils that move with moisture. Freeze-thaw cycles in winter and spring heave and crack concrete and masonry.
Heavy spring rains saturate soil, add pressure to basement walls and find gaps at the footing. Drainage, grading and downspout placement strongly affect how much water reaches the foundation. Put the question to the provider: how do these local conditions affect the diagnosis and the repair at your address?
