Construction Company in San Antonio, TX
From commercial foundation repair to elevated pilings construction, Bats Foundation Repair delivers structural construction services built for Bexar County soil conditions. Free estimates.
Foundation work in San Antonio doesn't end with a residential slab. Commercial structures, elevated buildings, flood-zone homes, hillside properties, and sites with active drainage challenges all demand a broader range of structural construction expertise than a standard slab repair. Bats Foundation Repair, a local construction company in San Antonio, brings that expertise to every job — combining deep knowledge of Bexar County's soil and geology with the structural construction capabilities to handle complex projects that go beyond the scope of typical foundation companies.
From commercial foundation repair to elevated pilings construction, from tunneling beneath an occupied structure to house raising and lifting, our team handles the full scope of structural construction services that the San Antonio market requires. Every project starts with a free estimate and is executed by crews who have been working in this specific soil environment for a combined 40+ years.
The Balcones Escarpment runs directly through Bexar County — the geologic boundary where the Texas Hill Country meets the Coastal Plain. Properties on the west side sit on shallow limestone over fractured rock. Properties on the east side sit on deep, aggressive Houston Black Clay. Properties at the transition zone can have both soil types within the same lot. Every structural construction decision in San Antonio has to account for which geology you're in — and what that geology does under load, moisture change, and seasonal stress.
Commercial Foundation Repair in San Antonio, TX
San Antonio's commercial real estate base is as diverse as its residential market — retail centers, medical office buildings, restaurants, warehouses, hospitality properties, military-adjacent commercial developments, and multi-unit residential all face the same Bexar County clay conditions that damage residential foundations. The difference is scale, urgency, and the operational stakes involved when a commercial building's foundation starts to move.
Bats Foundation Repair provides commercial foundation repair across the San Antonio metro, applying the same diagnostic discipline and proven repair methods we use in residential work — scaled to the larger footprints, heavier loads, and operational constraints of commercial structures.
How Commercial Foundation Repair Differs From Residential
Load magnitude: Commercial slabs carry significantly heavier and more concentrated loads than residential slabs. Repair methods must account for live loads, equipment loads, and foot traffic volumes that residential piers aren't designed for.
Operational continuity: Most commercial clients cannot shut down operations for a repair. We plan commercial jobs around operational schedules — sequencing pier installation, tunneling, and lifting work in phases that keep the business running throughout the process.
Documentation requirements: Commercial foundation repair often requires documentation for insurers, lenders, property managers, and tenants. We provide thorough written assessments, repair specifications, and completion documentation for every commercial job.
Post-tension slab considerations: Many San Antonio commercial buildings use post-tensioned slabs. These require specific drilling and pier placement protocols to avoid cutting tendons — a critical technical distinction that not every foundation company gets right.

Commercial Warranty
Bats Foundation Repair's lifetime transferable warranty extends to commercial pier installations. For property owners and investors, this means the warranty value transfers with the asset at the time of sale — a meaningful differentiator in commercial real estate transactions where foundation history is part of the due diligence record.
House Leveling in San Antonio, TX
House leveling is the process of correcting differential settlement — restoring a home that has dropped unevenly across its footprint back to a level plane. In San Antonio, differential settlement is the expected long-term outcome of building on Houston Black Clay. The clay doesn't move uniformly. It moves more under some sections of the foundation than others, depending on soil moisture distribution, drainage patterns, tree root activity, and the sun exposure on different sides of the structure. Over years, those differences accumulate into measurable elevation changes across the slab.
A house that is out of level is a house under continuous structural stress. Doors bind because door frames have racked. Drywall cracks because walls are being pulled in directions they weren't designed to resist. Floors slope because the slab beneath them has dropped at one end. Bats Foundation Repair corrects that settlement — bringing the foundation back toward its original elevation and relieving the stress that differential movement has placed on the structure above.
The House Leveling Process in San Antonio
Elevation survey: We establish the current elevation of the slab at multiple reference points across the footprint using precision instruments — telling us exactly how much differential movement has occurred and where it is concentrated.
Soil and drainage assessment: We examine the soil conditions, drainage patterns, and moisture sources around the foundation perimeter to identify the drivers of the settlement — because leveling without addressing what caused it just sets up a repeat.
Pier installation and lift: Piers are installed at the settled locations and the foundation is carefully lifted toward level using hydraulic equipment. The lift is controlled — raising too fast or too far causes new cracking. Our crews work incrementally.
Interior check and documentation: After the lift, we walk the interior with the homeowner, document the elevation readings before and after, and review what to expect as the structure settles into its corrected position over the following weeks.
Neighborhoods With High House Leveling Demand in San Antonio
Alamo Heights and Olmos Park — 1930s through 1950s homes on deep Blackland Prairie clay with decades of accumulated differential settlement
Converse, Universal City, and Live Oak — large concentrations of 1970s through 1990s residential on active Bexar County Vertisol
Southtown, King William, and Government Hill — historic structures where shallow original footings have been moving for 80 to 100 years
Leon Valley and Northwest San Antonio — Edwards Plateau edge soils that create fast void formation and uneven slab support
House Raising and Lifting in San Antonio, TX
House raising and lifting is a distinct service from house leveling. Where leveling corrects differential settlement across the slab footprint, raising physically elevates the entire structure — intentionally lifting the home to a higher elevation for a specific structural or practical purpose. It is a more complex, more involved process that requires careful engineering, temporary shoring, and precision execution. Bats Foundation Repair provides house raising and lifting services for San Antonio homeowners who need the full structure elevated, not just leveled.
When House Raising Is the Right Solution
Flood zone compliance: FEMA flood zone requirements and local floodplain regulations sometimes require that existing structures be raised to a minimum Base Flood Elevation (BFE). Raising to meet BFE requirements can reduce flood insurance premiums dramatically and may be required for property financing.
Transitioning from slab to elevated construction: In some cases, a home on a slab foundation needs to be converted to an elevated pier and beam or elevated piling system — either for flood mitigation, significant foundation remediation, or to address a site condition that makes a continuous slab impractical going forward.
Foundation replacement: When a foundation has failed beyond repair and needs to be fully replaced, raising the structure off the existing foundation allows the old foundation to be removed and a new one constructed beneath the elevated home.
Grade and access changes: Site grading, road improvements, or utility work that changes the elevation relationship between the structure and the surrounding grade sometimes require lifting the home to maintain proper drainage, access, and code compliance.
San Antonio Flood Zone Context
The San Antonio River basin, Salado Creek, Leon Creek, and Olmos Creek all pass through established residential neighborhoods in Bexar County. The 100-year and 500-year floodplain boundaries affect thousands of homes across the city. For homeowners in these zones, house raising is not a last resort — it is sometimes the most practical path to long-term flood protection and affordable flood insurance.
Foundation Tunneling in San Antonio, TX
Tunneling is the method Bats Foundation Repair uses to access the soil beneath a slab at interior locations where exterior excavation isn't possible. When a foundation needs piers installed under the center of a home — not just around the perimeter — tunneling is how we get there without tearing out your floors.
The process involves excavating a narrow tunnel from an exterior access point, running beneath the slab to the interior locations where pier installation is required. The tunnel provides working access for our crews, allows them to excavate the pier holes at the correct locations, install the piers, and complete the work — then backfill the tunnel and restore the access point. The floors remain intact throughout.
Why Interior Pier Placement Matters
Slab foundations in San Antonio don't just settle at the perimeter — they can settle in the interior as well, particularly under load-bearing walls, heavy appliances, or areas where clay void formation has been concentrated. Perimeter piers alone can't correct interior settlement. To properly level a foundation that has dropped in the middle, piers need to be placed at the interior drop points. Tunneling makes that possible without a demolition project inside the home.
What to Expect During Tunneling Work in San Antonio
Exterior access point excavation — typically in the yard adjacent to the home, kept as small as the work requires
Tunnel dimensions allow trained crew access while minimizing disruption to the surrounding soil and landscaping
Pier installation at designated interior points as specified in the foundation repair plan
Backfill of the tunnel with compacted material after pier installation is complete
Restoration of the exterior access point — lawn, landscaping, and hardscape returned to pre-work condition
The living space inside the home is not disturbed — no floor demolition, no interior excavation, no interior mess
Elevated Pilings and Stilts Foundation Repair in San Antonio, TX
Elevated piling foundations — also called stilt foundations — lift the structure entirely above grade, supporting the home on a network of deep piers or pilings driven to load-bearing depth. This construction type is required in FEMA high-risk flood zones, common in properties near the San Antonio River and Bexar County creek corridors, and used in hillside construction where conventional slab or pier and beam foundations aren't practical.
These systems require specialized repair expertise. When elevated piling foundations settle, shift, or show signs of structural distress, the failure mode and the repair approach are fundamentally different from standard slab or pier and beam repair. Bats Foundation Repair has the experience and the methods to assess and repair elevated piling and stilt foundation systems across the San Antonio metro.
Common Failure Modes in Elevated Piling Foundations
Piling settlement: Individual pilings that have sunk deeper into the soil due to inadequate bearing capacity at the original installation depth — more common in areas where the soil profile transitions unexpectedly or where groundwater has altered the bearing capacity of the soil column.
Piling lateral movement: Horizontal displacement of pilings due to soil pressure, erosion, or impact loading. Even minor lateral movement at the base translates to measurable out-of-plumb at the structure above.
Piling deterioration: Concrete pilings that have cracked, spalled, or suffered corrosion of internal reinforcement over years of exposure to Bexar County soil moisture and chemistry. Wood pilings that have rotted or been compromised by moisture and insects.
Connection failure: Deterioration of the connection between the piling cap and the beam system above — often the first failure point in older elevated construction as hardware corrodes and wood members shrink away from their original bearing positions.
Elevated Construction and San Antonio Flood Zones
FEMA's National Flood Insurance Program requires structures in Special Flood Hazard Areas (SFHA) to be built or elevated to the Base Flood Elevation. Many properties in San Antonio's creek and river corridors were built before current FEMA mapping and floodplain ordinances — and some were elevated to standards that no longer meet current requirements. Bats Foundation Repair works with homeowners in these zones to assess existing elevated foundations and repair or upgrade them to current structural standards.
