Foundation repair and waterproofing contractors work in one of the most litigious segments of Texas construction. Texas soil — primarily expansive clay in the DFW Metroplex, Central Texas, and Houston — moves with moisture, and foundations in this state have a higher failure and movement rate than in most of the country. The combination of active soil conditions, homeowner emotion around structural issues, and the long time lag between a repair and a resettlement claim creates a distinctive insurance challenge.
Whether you install piers (push piers, helical piers, pressed concrete pilings), inject polyurethane foam for void filling, or apply waterproofing membranes and drainage systems in below-grade applications, the work carries completed operations exposure that outlasts many GL policies. Getting the right structure — particularly for completed operations — is the critical piece of this trade's insurance program.
The Texas Soil Context
Understanding why this matters for insurance requires understanding the soil. Texas Blackland Prairie and Houston-area soils are predominantly expansive clays (montmorillonite) that absorb water and swell, then dry and shrink. This seasonal movement can be several inches. A properly repaired foundation on expansive clay depends on maintaining consistent soil moisture — conditions outside your control as the contractor.
This creates a claims environment where homeowners who experience settlement or cracking after a repair argue that the repair failed, while contractors argue that the soil moved again after the repair was complete and properly done. These disputes are common, often end up in mediation or litigation, and generate claims on completed operations coverage years after the job was closed. Understanding this environment helps explain why foundation repair contractors need completed operations coverage with adequate limits and tail duration.
General Liability
General liability covers property damage and bodily injury you cause to others. For foundation and waterproofing contractors, the GL exposures span both ongoing operations and completed operations.
Ongoing operations exposures
During the work itself, you're excavating around foundations, drilling, operating jacking equipment, and applying chemicals. Potential ongoing GL claims include:
- Cracked utility lines during excavation (call 811 before digging — compliance documentation matters)
- Settlement or movement of adjacent structures caused by excavation disturbance
- Water intrusion or flooding events caused by improper temporary drainage during work
- Property damage to the home's exterior, landscaping, or adjacent hardscaping during access and work
- Damage to below-grade utilities (gas lines, electrical conduit, drainage) during boring or pier driving
Completed operations — the long-tail exposure
The more significant GL exposure for this trade is completed operations: claims that arise after the work is done. Common completed operations claims include:
- Foundation settlement after pier installation — the piers move, shift, or the bearing stratum wasn't reached
- New cracking in walls, floors, or exterior that the homeowner attributes to the repair
- Waterproofing membrane failure that allows moisture intrusion, leading to mold and interior damage
- Drainage system failure that redirects water into the foundation rather than away from it
- Movement of adjacent structures caused by changes in soil moisture resulting from your work (a waterproofing system that dries out soil on one side of a property can cause differential movement on the neighboring foundation)
In Texas, the statute of repose for construction defect claims is ten years from substantial completion. Foundation and waterproofing claims frequently arrive two to five years after completion, and occasionally later. Completed operations coverage must be structured to remain in place through this exposure window.
Completed operations aggregate — the number that matters. Your GL policy has a general aggregate limit and a products-completed operations aggregate limit. These are separate buckets. A $2 million general aggregate and a $2 million products-completed operations aggregate give you $4 million total, not $2 million shared. If you do significant volume and have had prior completed operations claims, review whether your products-completed operations aggregate is adequate for your current risk level.
Soil subsidence and settlement exclusions
Some GL policies include exclusions for earth movement, soil subsidence, or settlement. These exclusions can be applied by carriers to deny completed operations claims on foundation work by arguing that the loss was caused by soil movement — an excluded cause — rather than defective workmanship. Review your policy for these exclusions and confirm with your broker how they apply to your work. Some carriers include explicit carve-outs for claims arising from construction operations; others apply the exclusion broadly.
Workers' Compensation
Foundation and waterproofing contractors work in physically demanding and potentially hazardous conditions. Workers' comp covers employee medical costs and lost wages from job-related injuries.
Common injury types for this trade:
- Musculoskeletal injuries: The physical work of pier driving, excavation, and carrying equipment in confined spaces around foundation perimeters generates back, shoulder, and knee injuries. These are the most common WC claim type for the trade.
- Confined space hazards: Crawl space work creates confined space hazards — limited air exchange, potential accumulation of gases (particularly near gas lines), and difficult exit in an emergency. Crawl space work should follow OSHA confined space protocols when applicable.
- Equipment operation: Hydraulic jacking equipment, drilling rigs, and boring equipment can cause crush and pinch injuries if not operated correctly.
- Chemical exposure: Polyurethane foam injection and waterproofing chemical applications expose workers to chemical fumes and skin irritants. Appropriate PPE and ventilation are required for these operations.
Texas is the one state where workers' comp is optional for most private employers. Foundation repair contractors doing residential work may operate without workers' comp if their homeowner clients don't require it. But contractors who work on commercial properties or who are hired as subs on GC-managed projects will typically face workers' comp requirements from the GC. Many foundation repair and waterproofing contractors carry workers' comp regardless because the physical injury exposure in this trade is real and the uninsured liability is significant.
Commercial Auto
Foundation repair and waterproofing contractors operate service trucks, trailers, and specialized equipment vehicles. Pier installation rigs and drilling equipment may be mounted on trucks or transported on trailers. Commercial auto covers liability and physical damage for your business vehicles.
Standard limits for commercial contractor vehicles are $1 million combined single limit for liability. For contractors who operate heavy drilling rigs or specialized foundation equipment on public roads, confirm the vehicle classification is correct for the type of equipment being operated — oversized or overweight loads require permits.
Tools and Equipment (Inland Marine)
Foundation repair equipment is expensive and specialized. A hydraulic jack set, pier driving equipment, helical anchor installation drive heads, boring equipment, and polyurethane foam injection rigs represent significant capital investment. A fully-equipped pier installation truck and trailer can have $100,000 to $300,000+ in equipment value.
Commercial auto physical damage covers the truck. Inland marine covers the equipment it carries. For contractors with significant equipment schedules, the inland marine policy is a meaningful coverage — equipment theft and damage from job site incidents are real exposures. Price inland marine on a replacement cost basis to ensure total losses are covered at replacement value, not depreciated value.
What Homeowners and Commercial Clients Require
The certificate requirements for this trade vary significantly by client type:
Residential homeowners
Homeowners typically don't issue formal subcontract agreements with detailed insurance requirements. They're often buying the service directly. However, the larger foundation repair companies offer warranties and guarantees, and savvy homeowners sometimes ask for evidence of insurance before authorizing work. A basic GL certificate showing $1 million in coverage satisfies most homeowner requests. The homeowner as certificate holder with no additional insured endorsement is common for purely residential consumer work.
Commercial and GC-managed projects
Commercial property owners, GCs managing commercial projects, and property managers who hire foundation repair or waterproofing contractors as subs have standard contractor requirements:
- GL: $1 million per occurrence, $2 million aggregate
- WC: Statutory limits
- Auto: $1 million CSL
- Additional insured: GC/owner named as additional insured, ongoing and completed operations
- Primary and noncontributory
- Waiver of subrogation on GL, WC, and auto
For commercial work that involves structural remediation of occupied buildings or work in proximity to other occupied structures, some clients add umbrella requirements of $2 million or more.
Same-day certificates for property managers. Property management companies that maintain ongoing vendor relationships with foundation repair and waterproofing contractors need certificates quickly when a repair is authorized. We issue certificates in 15 minutes so service jobs don't wait on paperwork. For more on certificate requirements, see our Certificate of Insurance Guide.
What Waterproofing and Foundation Repair Insurance Costs in Texas
Premiums reflect the completed operations tail risk and the physical hazard of the work. The following ranges apply to a small to mid-size operation with 3 to 10 employees and $400,000 to $2 million in revenue.
| Coverage | Typical range | Key driver |
|---|---|---|
| General liability | $2,500 – $9,000/year | Revenue, completed operations history, residential vs. commercial |
| Workers' compensation | $4,000 – $18,000/year | Payroll, class codes, experience mod |
| Commercial auto | $2,000 – $7,000/year | Fleet size, driving records |
| Inland marine / equipment | $1,000 – $5,000/year | Equipment schedule value |
| Umbrella ($1M – $2M) | $1,000 – $4,000/year | Underlying limits, class |
Total range: approximately $10,000 to $40,000+ per year for a typical operation. Contractors with significant prior completed operations claims, those doing large commercial remediation projects, or those with high equipment values will be at the high end or above it.
Managing the Completed Operations Exposure
Beyond buying adequate completed operations coverage, there are operational practices that help manage the tail risk:
Warranty scope documentation
Foundation repair warranties are central to your business model — they're often a key selling point. But warranty scope matters for insurance. A warranty that guarantees "no future movement" is broader than one that guarantees "the installed piers will not fail." The first warranty creates potential liability for anything that moves after your work. The second is more narrowly tied to your workmanship. Review your warranty language with legal counsel to ensure the scope of what you're guaranteeing is consistent with what your insurance actually covers.
Pre-work documentation
Photograph the property thoroughly before starting — inside and out. Document existing cracks, movement, and damage before your crew does anything. This pre-work documentation is your defense when a homeowner claims that cracks that existed before your work were caused by your repair. It's also important for establishing baseline conditions for the soil and adjacent structures.
Post-repair monitoring records
For larger jobs and commercial work, consider documenting post-repair conditions at intervals — elevation measurements, crack documentation, photographs. This creates a record that the repair held for some period before any new movement occurred, which supports your position that post-repair settlement resulted from soil conditions rather than workmanship failure.
Frequently Asked Questions
Does my GL cover claims from homeowners who claim my foundation repair didn't fix their problem?
This depends on the nature of the claim. If the homeowner is claiming your repair was defective — that the piers didn't reach bearing stratum, that the waterproofing membrane was improperly applied — that's a completed operations claim that GL can cover (the "your work" exclusion doesn't eliminate coverage for damage caused by defective work to other property). If the homeowner is simply claiming the repair didn't work and wants their money back, that's a contract claim, not an insurance claim, and GL doesn't cover it. The distinction matters significantly for how you respond to warranty claims.
Is foundation repair work considered construction that triggers the Texas statute of repose?
Texas Occupations Code Chapter 16 applies the ten-year statute of repose to "construction or repair of an improvement to real property." Foundation repair is generally considered an improvement to real property. This means the legal window for claims against you runs ten years from substantial completion, which is why completed operations coverage duration matters for this trade. Consult a Texas attorney for advice specific to your situation.
Do I need a license for foundation repair work in Texas?
Texas does not have a state-issued foundation repair contractor license. However, if your work involves excavation that intersects with utility lines, Texas requires notification through 811 (the "call before you dig" system). Some municipalities have permit requirements for foundation repair and waterproofing work. The absence of a state license requirement doesn't reduce your insurance obligations — liability follows the work regardless of licensing status.
