Ohio Concrete Contractor Insurance

You poured a driveway, a patio, a commercial slab, standard job. A few weeks later, cracking shows up that's well beyond normal shrinkage cracking, the kind that points to a bad batch from the supplier, wrong water-cement ratio, contamination, something that wasn't your workmanship.

The customer wants it fixed. You call your insurance company expecting general liability to step in. That's when you find out general liability policies exclude damage to "your work," repairing or replacing your own completed work isn't treated as a liability claim, even when the underlying cause was a bad load of concrete that wasn't really your fault. You're left negotiating with the supplier while eating the cost of the repour in the meantime.

Here's what most concrete contractors don't know, some carriers offer a buyback for exactly this, an endorsement that restores coverage for repair or replacement costs tied to defective material or workmanship. It's not standard, and not every carrier offers it, but if you've never had anyone confirm whether your policy includes it, you don't know whether a bad batch is your problem alone or something your policy actually responds to.

At Equilibrium Insurance Partners, we're Certified Insurance Counselors (CIC). We know which carriers offer this buyback and we make sure you know what you're carrying before a bad batch turns into a repour you're paying for twice.

There's a difference. You'll know exactly what that difference is the day a slab cracks for reasons that weren't your fault.

Concrete contractor insurance isn't one policy. It's a program built around the specific risks of placing and finishing concrete, driveways, patios, sidewalks, foundations, and slabs, across residential and commercial properties in Ohio.

Concrete work carries a distinct exposure most trades don't, your finished product can fail due to factors outside your control, a bad batch, contaminated water, improper curing conditions, and standard general liability treats "fixing your own work" very differently than it treats "damage you caused to someone else's property." Understanding which side of that line a given problem falls on, and whether your policy has a buyback that changes the answer, is central to what concrete contractors actually need from their coverage.

Ohio requires concrete contractors to carry liability coverage to maintain operations. Most concrete contractors we talk to have never had anyone confirm whether their policy includes a buyback for defective material or workmanship, or how their completed operations coverage treats slabs and driveways that heave or crack after a season of Ohio's freeze-thaw cycles.

General Liability Insurance

Your foundation. General liability covers bodily injury and property damage resulting from your operations, to other property and other people. Equipment damages a customer's landscaping during a pour. General liability responds, assuming your limits are adequate.

Minimum recommended limits for Ohio concrete contractors are $1,000,000 per occurrence and $2,000,000 aggregate. Commercial GCs often require higher limits.

Coverage for Defective Materials and Workmanship

Standard general liability policies exclude the cost of repairing or replacing your own completed work, this is often called the "your work" exclusion. It applies even when the underlying cause was a bad batch from the supplier rather than your workmanship. A slab cracks from contaminated concrete, the repour is on you, not your policy, unless something specific changes that.

Some carriers offer a buyback endorsement that restores coverage for repair or replacement costs tied to defective material or workmanship. This isn't standard, and not every carrier offers it. If you've never had anyone confirm whether your policy includes this, you don't actually know whether a bad batch is your problem alone or something your policy responds to.

Completed Operations Coverage

Concrete work has two distinct failure modes that show up after the job is done, and both are covered under completed operations, when the coverage is structured to address them.

The first is surface heaving. Slabs, driveways, and sidewalks installed over improperly prepared subgrade can heave, settle unevenly, or crack after a season or two of Ohio's freeze-thaw cycles. Someone trips on an uneven edge or a lip between slabs and gets hurt, that's a bodily injury claim to a third party.

The second is foundations. A foundation that develops cracking or settling issues after the job is complete can lead to water intrusion into a basement, or structural problems with the building above it. That's property damage to the structure, discovered well after the pour.

Both of these are completed operations claims, surfacing months or years after the work, on different parts of the property, with different consequences. Confirm your completed operations coverage extends through at least a couple of Ohio winters for the heaving scenario, and confirm it would respond to a foundation-related claim discovered later as well.

Workers' Compensation

If you have employees in Ohio, workers' comp is required by law. Ohio is a monopolistic state, meaning you purchase through the Bureau of Workers' Compensation (BWC), not a private carrier.

Concrete work involves heavy lifting, repetitive kneeling during finishing, and direct skin contact with wet concrete, which is caustic and can cause chemical burns with prolonged exposure. Your classification codes need to accurately reflect this work. Misclassified employees are one of the most common causes of audit surprises we see.

Commercial Auto

Your trucks and trailers hauling forms, tools, and equipment need commercial auto coverage. Not personal auto. If one of your crew is in an accident hauling materials to a job and you're relying on personal auto policies, you're likely uninsured for that loss.

Hired and non-owned auto coverage matters too if your crew uses personal vehicles for work. Most concrete contractors don't think about this until there's a claim.

Inland Marine / Tools and Equipment

Your power trowels, saws, vibrators, forms, and pumps are not covered under general liability. They're not covered under commercial property when they're off site. Inland marine coverage protects your gear on job sites, in transit, and in storage.

Concrete equipment represents real value, and job sites are often unsecured between visits. Theft and job site loss are common exposures.

Commercial Umbrella

A defective batch on a large commercial slab, or a freeze-thaw related injury claim on a sizable driveway or parking area, can produce costs well beyond a standard general liability limit once repour, remediation, and any injury claims are factored in. An umbrella policy sits above your general liability and extends your limits for exactly these kinds of high-severity losses.

If you're doing larger residential or any commercial concrete work, the gap between your contract value and your potential exposure is wider than it looks. Umbrella is how you close that gap.



Assuming a bad batch is automatically covered. Standard GL excludes repairing or replacing your own completed work, even when defective material caused the problem. If your policy doesn't have a buyback for this, a bad batch is your cost alone.

Not knowing your completed operations timeline. Freeze-thaw related heaving and cracking can take a full winter or more to show up. If your completed operations coverage doesn't extend that far, you have a gap that won't surface until it's too late to fix.

Buying on price alone. The cheapest policy is the most expensive one when you have a claim, and for concrete, a policy without a defective material buyback can leave you paying for a repour out of pocket on top of the original job cost.

Misclassifying employees on workers' comp. Ohio BWC audits. If your classifications are wrong you'll pay at audit. Get them right upfront.

Using 1099 crews without verifying their coverage. If subcontracted finishing crews don't carry their own workers' comp and general liability, Ohio BWC may classify their payroll as yours at audit.

Not understanding GC certificate requirements. Sending the wrong certificate or carrying limits that don't meet a contract requirement can get you pulled from a job or removed from a bid list.

Skipping inland marine. Power trowels, saws, and forms aren't covered under GL. One theft or loss event can set your operation back significantly.

Assuming the certificate means the policy is active. A certificate is a snapshot in time. It doesn't guarantee ongoing coverage. Verify, track, and re-verify.



Most concrete contractors don't dread audit season until they get hit with an unexpected bill. Here's why it happens and how to avoid it.

Your workers' comp and general liability premiums are based on estimated payroll and revenue at the start of the policy year. At the end of the year, the carrier audits your actual numbers. If your actuals are higher than your estimates, you owe the difference. Sometimes significantly.

The most common causes of bad audits we see in concrete:

Underreported payroll. Either intentional to get a lower quote, or because the business grew mid-year and nobody updated the policy. Both result in a large audit bill.

Wrong classification codes. Placement, finishing, and form work can carry different rates depending on how they're classified. Getting it wrong at the start of the policy year creates audit exposure.

1099 crews without their own coverage. If subcontracted finishing crews don't carry their own workers' comp, BWC may classify their payroll as yours at audit.

No mid-year updates. You added a crew for the busy season. You took on a larger commercial concrete contract. None of it was reported to your carrier. Audit time is when it all catches up.

The fix is simple. Build your policy on accurate numbers. Verify every subcontracted crew carries their own active coverage. Update your carrier mid-year when your business changes.
