If you run a slabjacking, mudjacking, or polyjacking business, you know that concrete leveling work comes with real risks that most contractors' policies weren't designed to handle. Mud injection, polyurethane foam lifting, and stone slurry work all carry unique exposures — property damage from over-injection, chemical spill liability, specialized equipment vulnerability, and completed-operations claims that surface months after the job.
This guide covers everything you need to know about insuring a slabjacking or concrete leveling business properly.
What Is Slabjacking Contractor Insurance?
Slabjacking insurance is a commercial insurance package tailored to the specific risks of concrete leveling operations. It typically combines several coverage types into a comprehensive program:
- **General liability** — covers third-party property damage and bodily injury
- **Workers compensation** — covers crew injuries on the job
- **Commercial auto** — covers pump trucks and rigs
- **Tools and equipment** — covers injection pumps, drills, and mixing equipment
- **Contractor bond** — satisfies licensing requirements
The key difference between slabjacking insurance and generic contractor insurance is that the policies are specifically underwritten to recognize and cover the risks unique to mud injection and concrete leveling work — not just exclude them.
Why Generic Contractor Policies Often Fall Short
Many slabjacking contractors make the mistake of buying a standard general contractor's policy and assuming it covers their work. It often doesn't — or at least not fully. Here are the most common exclusions that create problems:
Subsurface Work Exclusions
Some GL policies exclude claims arising from work performed below ground level. Slabjacking by definition involves injecting material beneath a concrete slab — directly into the subsurface. If your policy has this exclusion, a claim from an injection-gone-wrong may be denied.
Earth Movement Exclusions
Concrete leveling involves changing the position of earth and concrete. Policies with earth movement exclusions may deny claims related to ground disturbance during mud injection operations.
Completed Operations Gaps
Settlement claims in concrete leveling often arise weeks or months after the job. If a homeowner's slab re-settles or cracks three months later and attributes it to your work, you need completed operations coverage to respond. Some budget policies drop this coverage to lower premiums.
Chemical Pollution Exclusions
Polyjacking uses expanding polyurethane foam — a chemical product. If foam spills during injection or migrates off-property, standard GL pollution exclusions may deny coverage for cleanup costs and third-party claims.
What Coverage Does a Slabjacking Business Need?
General Liability Insurance
This is the foundation of any slabjacking insurance program. A standard limit is $1M per occurrence / $2M aggregate. If you work on commercial properties or large HOA projects, you may need $2M/$4M or higher.
GL should explicitly cover: - Property damage from grout injection operations - Bodily injury at job sites - Completed operations - Personal and advertising injury
Workers Compensation
Required in most states once you have employees. Covers medical expenses and lost wages for crew injuries. Key risks for slabjacking crews include heavy equipment accidents, chemical exposure, and musculoskeletal injuries from drilling and ground-level work.
Commercial Auto
Your pump truck and any trailers need commercial auto coverage. Personal auto policies exclude business use — if you're driving to job sites for your business, you need a commercial policy.
Tools and Equipment
Injection pumps, foam rigs, core drills, and mixing equipment represent significant capital. A dedicated tools and equipment policy covers theft, accidental damage, and breakdown wherever your gear is — job site, truck, or yard.
Contractor Bond
Most states require a surety bond before issuing a concrete leveling contractor license. Bond amounts vary by state ($5,000–$25,000 is common). Premiums are typically 1-3% of the bond amount annually — a $10,000 bond often costs $100–$300/year.
How Much Does Slabjacking Insurance Cost?
Premiums vary based on:
- **Annual revenue** — the primary rating factor for GL
- **Number of employees** — affects workers comp premium
- **Number and value of vehicles** — affects commercial auto
- **Claims history** — prior losses increase rates
- **States of operation** — some states have higher workers comp rates
As a rough guide, a small slabjacking operation (1-3 employees, $250K annual revenue) might pay $3,000–$6,000/year for a full package. Larger operations with multiple trucks and crews will pay more. The cost of not having proper coverage — a single denied claim from an over-injection incident — can dwarf a year's worth of premium.
Finding the Right Insurance Partner
Not every commercial insurance broker understands slabjacking. When evaluating carriers and brokers:
- Ask specifically about subsurface work exclusions
- Confirm completed operations coverage is included
- Ask about pollution liability for polyjacking foam
- Verify the broker has written concrete leveling policies before
