Expert Foundation Repair Services for San Antonio Homes & Businesses
San Antonio foundations face a distinct set of challenges. Expansive clays common across much of Bexar County swell dramatically after heavy rains and shrink during prolonged dry spells, while northern and western areas near the Edwards Plateau encounter shallow limestone and caliche that create abrupt transitions in bearing capacity. These conditions produce differential settlement, cracking, and uneven floors that generic approaches often fail to resolve permanently.
Whether your property sits on a concrete slab or a pier-and-beam foundation, our team begins with a thorough evaluation to identify the root cause of movement. We then recommend the right combination of steel or concrete piers, helical systems where limestone is present, drainage improvements, and other measures matched to your specific soil profile and structural needs.
Our goal is lasting stability—repairs engineered to help your home or commercial building withstand San Antonio’s wet-dry cycles and varied ground conditions for decades.

Why San Antonio Homeowners Choose Dura Pier

We have repaired more than 45,000 foundations by combining quality workmanship, honest assessments, and systems built to perform long-term.
San Antonio’s combination of high-plasticity clays, limestone formations, and fluctuating moisture demands site-specific solutions rather than one-size-fits-all fixes. We start with a detailed inspection so the recommended repair plan matches your foundation type, soil conditions, and long-term structural requirements.
When you choose Dura Pier, you work with a team focused on transparency, engineering accuracy, and respectful service. We aim to restore your confidence in the home while safeguarding its value for years ahead.

Foundation Repair in San Antonio
San Antonio foundations contend with expansive clays that change volume significantly between wet and dry periods, plus limestone and caliche zones that can produce uneven support. Over time this leads to settlement, cracks in walls and brick, sticking doors and windows, and sloping floors. Dura Pier provides engineered repairs that stabilize the structure and address the source of movement.
- Dura Lock® piling system designed to transfer loads to stable soil or rock where appropriate
- Precision hydraulic lifting to restore settled foundations and improve alignment
- Expert repair for both concrete slab and pier-and-beam foundations
- Solutions for settlement, wall and brick cracks, uneven floors, and structural movement
- Lifetime transferable warranty on qualifying structural foundation repairs
Concrete Lifting in San Antonio
Shifting soils and changing moisture cause driveways, sidewalks, patios, and pool decks across San Antonio to settle. Our concrete lifting restores these surfaces quickly and cleanly without full replacement.
- High-density polyurethane foam injection (polyjacking) for precise lifting and stabilization
- Small injection points that minimize disruption and preserve appearance
- Restoration of proper slope to improve drainage and reduce standing water
Ideal for driveways, sidewalks, patios, garage floors, and pool decks - Fast-curing material that often allows same-day use
Sewer Line Repair in San Antonio
A damaged sewer line beneath your home can do more than cause plumbing problems. Leaks can saturate the surrounding soil, weaken the support beneath your foundation, and contribute to settlement or structural movement over time. Dura Pier provides sewer line repair in San Antonio with a coordinated approach that addresses both the plumbing issue and its impact on your foundation.
- Video camera inspections to accurately locate leaks, cracks, and damaged pipe sections
- Trenchless repair options available when appropriate to minimize excavation and protect your property
- Targeted excavation and pipe replacement for severely damaged sewer lines
- Soil stabilization and remediation in areas where leaks have compromised foundation support
- Integrated foundation and plumbing solutions that reduce disruption and help protect your home’s long-term structural integrity
Drainage Solutions in San Antonio
Effective drainage is one of the best ways to protect your foundation from unnecessary movement. In San Antonio, heavy downpours, uneven grading, and fluctuating moisture levels can allow water to collect around your home’s foundation, increasing hydrostatic pressure and contributing to soil expansion, erosion, and settlement. Dura Pier designs customized drainage solutions that help direct water away from your home and maintain more consistent soil conditions year-round.
- French drain systems to capture and redirect subsurface water away from the foundation
- Surface drains, catch basins, and channel drains to manage stormwater and prevent pooling
- Yard grading and regrading to create positive drainage away from your home’s foundation
- Downspout extensions and underground drain lines to safely move roof runoff away from the structure
- Comprehensive drainage systems tailored to your property’s layout, soil conditions, and water management needs
The Technology Behind Stronger Foundations
Most foundation repairs rely on generic pier systems.
Dura Lock® is different.
Standard systems often underperform in the reactive clays and mixed limestone conditions found throughout the San Antonio area. Our proprietary Dura Lock® and Dura Lock XD® systems use bolted segments that are driven and tensioned for superior grip, alignment, and resistance to both downward settlement and upward heave.
Key advantages include deeper penetration capability, stronger inter-segment connections, efficient installation, and permanent performance supported by our lifetime transferable warranty. This technology has been refined over decades specifically for Texas soils.
San Antonio Foundation Repair FAQs
Do I need a permit for foundation repair in San Antonio?
Usually yes for structural work. We pull permits as part of the job rather than leaving it to you, and we confirm current requirements before scheduling. If your property sits over the Edwards Aquifer recharge zone, some excavation and drainage work carries additional approval steps on top of the standard permit.
How do I know if my foundation is really moving?
Measurement is the only reliable answer. Some settling is normal in a home’s first year or two, and thin shrinkage cracks in a slab are ordinary. Real movement shows a pattern: cracks that widen over months, doors that stick in one season and free up in another, and floor elevations that vary more than construction tolerance. One set of readings gives you a baseline.
Does it matter which side of town I live on?
It changes the whole diagnosis. South and east of the fault line, deep Blackland clay swells and shrinks with the seasons and lifts a slab unevenly. North and northwest, there is very little soil and rock is often close to the surface, so movement usually traces to fill placed on a sloped lot or water finding a path through the limestone.
What does foundation repair cost in San Antonio?
It depends on how many piers your home needs, how deep they have to go, and whether drainage work is part of the job. Across this area, moderate repairs commonly land in the low-to-mid thousands, and whole-house corrections with drainage run higher. Depth is the biggest variable here because it changes so much across the city. Our on-site evaluation is free.
How long does the work take?
Most single-family pier jobs take a few days of actual work. Rock excavation on the north side, tunneling under a slab, and drainage work all add time. The calendar window is always wider than the working days because it includes scheduling, any permit, and the plumbing test after the lift. You get a date range in writing before we start.
Does homeowners insurance cover this?
Rarely, when soil movement is the cause. Texas policies generally cover sudden and accidental damage. Gradual settling from clay shrinking and swelling is usually treated as maintenance. A sudden plumbing leak under the slab is sometimes handled differently. Read your exclusions and call your carrier before you count on coverage.
Will my foundation move again after the repair?
The repaired sections are supported on piers that reach firm bearing, and those are covered by a lifetime transferable warranty. What the piers do not control is the soil around the rest of the house. That is why drainage and steady moisture around the perimeter matter after the work is done as much as before it.
How deep do the piers go?
It depends entirely on where your house sits. On the north side, rock can be within a few feet of the surface and piers are often short. On the clay side of town, they have to reach past the layer that keeps moving, which is deeper. We drive each pier until it hits firm bearing rather than to a set depth, so the number varies even across a single lot.
