Why slabs move
- Original construction issues such as poor compaction or fill
- Poor drainage and grading that send water toward the foundation
- Expansive clay that swells when wet and shrinks when dry
- Tree roots that dry the soil near the house
- Plumbing leaks under the slab that wash out or saturate soil
Slab repair methods compared
| Method | How it works | Notes |
|---|---|---|
| Pressed or drilled piers | Piers placed under the footing down to stable soil, then the slab is lifted | Common for settlement. |
| Drainage and moisture control | Grading, gutters, drains and watering practices | Reduces future movement. |
| Mudjacking | A cement-based slurry is pumped to lift the slab | Used for light settlement and flatwork. |
| 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. |
Slab leak testing
A plumbing pressure test or acoustic leak detection can show whether a supply line is leaking under the slab. Repairing a leak without addressing the soil can leave movement behind, so the plumbing and the foundation are assessed together.
Signs specific to slabs
- Exterior brick cracks near corners and doors
- Doors that rub in the frame or no longer close
- Floors that slope or feel hollow
- Wet spots or high water bills that suggest a slab leak
- Cracked floor tiles and gaps at baseboards
Questions to ask a foundation repair company
- How will you verify the result?
- What happens to landscaping, utilities and flooring during the work?
- What caused the movement, and how will you address the cause?
- Is the repair engineered, and can I see the design?
- What is the warranty, and is it transferable if I sell?
How a foundation visit works, step by step
Evidence comes first in a sound foundation assessment, and the repair proposal follows. Once you know that order, a diagnosis is easy to tell apart 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.
What shapes the written scope
Neighboring houses can need very different foundation work. A written scope should state what was found and which of these factors applied.
- The foundation type: slab-on-grade, post-tension slab, pier and beam, basement or crawl space
- Drainage, grading, gutters and plumbing leaks that feed the problem
- Access for equipment, utilities and landscaping, and any permit or engineer requirements
- The soil, especially expansive clay, and how wet or dry it has been
- How much the structure has moved and where, from elevation readings
Prepare your Corpus Christi home for the assessment
- Check gutters and downspouts and see where water goes near the foundation
- Take dated photos of cracks with a coin or ruler for scale
- Gather any earlier inspection reports, repair invoices and the home's construction year
- Look for leaks, wet spots and unusual water bills
- Note when doors started sticking and when cracks appeared
Safety and when an engineer should be involved
A structural engineer can evaluate movement independently of anyone selling a repair, and can design the repair. A report from an engineer is useful for a sale, an insurance claim or a large repair. Do not enter a crawl space or basement that has standing water or visible structural distress, and keep utility lines in mind before any digging.
Mistakes that make foundation problems worse
- Repairing cracks cosmetically without finding the cause.
- Choosing a repair before getting measurements and a cause.
- Ignoring drainage. Water at the foundation is the most common driver of movement.
- Planting large trees too close to the foundation.
- Over-watering or letting soil dry out completely around a slab in clay soils.
Foundation terms explained
- Underpinning: strengthening or deepening an existing foundation
- 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
- Elevation survey: measurements of floor heights to show movement
- Expansive clay: soil that swells when wet and shrinks when dry
Myths and facts
- Myth: you can skip an engineer. Fact: an independent opinion is useful for big repairs.
- Myth: a repair means the house will never move again. Fact: soil still changes, so drainage and monitoring matter.
- Myth: foundation problems come only from old age. Fact: water and soil are the main drivers.
- Myth: all cracks mean a failing foundation. Fact: many cracks are cosmetic.
- Myth: bigger piers are always better. Fact: the design depends on the load and the soil.
A checklist for this week
- Check doors and windows for sticking
- Gather inspection and repair records
- Check that downspouts discharge several feet away
- Look for plumbing leaks and unusual water bills
- Walk the outside of the house and photograph cracks with a coin for scale
What makes foundation work different in Corpus Christi
Corpus Christi sits on the Gulf coast with clay soils that swell when wet and shrink in drought, and many homes are built on concrete slabs. Wet and dry cycles move the soil under a slab and can cause cracks, uneven floors and sticking doors.
Coastal storms and flooding saturate soil and can undermine foundations and drainage. A high water table and salt air affect concrete, rebar and plumbing. Ask the provider how these local conditions shape the diagnosis and the repair at your address.
