Inland Marine Insurance for Concrete Contractors

How is What does Why Do Concrete Contractors Need Inland Marine?

When Inland Marine Pays — A concrete contractors Example

A concrete contractors operation completed work that developed water intrusion six months later. The completed operations claim included $88,000 in remediation and $35,000 in interior repairs.

Without proper inland marine coverage, this loss would come directly from business assets. The right policy covered defense costs, damages, and esolution management — allowing the business to continue operating.

Does Your Inland Marine Policy Actually Cover This? A Guide for Concrete Contractors

concrete contractors often assume their inland marine policy covers more than it does. Here is a practical guide to what is — and is not — covered:

Covered: A client’s employee is injured by your concrete contractors operations → yes, GL bodily injury. Your equipment damages a client’s property → yes, GL property damage. A completed project fails and causes damage → yes, completed operations (if your policy includes it).

Not covered: Your own employee is injured → no, that is workers comp. Your own equipment is damaged → no, that is inland marine or property. A client claims your professional advice was wrong → no, that is E&O. Pollution from your operations contaminates a neighbor → no, that is environmental liability.

The distinction matters because a denied claim costs you the full loss out of pocket — plus the premium you paid for coverage that did not apply.

Inland Marine classified and rated for Concrete Contractors?

Your inland marine premium starts with two classification systems that determine your base rate:

Workers Compensation: NCCI 5022 (Masonry — including concrete work) and 5213 (Concrete construction — NOT buildings) — base rate of $10.40–$18.20 per $100 of payroll per $100 of payroll. This rate is multiplied by your total payroll, then adjusted by your An EMR below 1.0 earns a premium credit; above 1.0 means a surcharge. (Source: NCCI Scopes Manual)

General Liability: ISO GL class code 91580 (Concrete contractors) — rated on revenue or payroll depending on the classification. Your loss history serves as a secondary rating factor. (Source: ISO Commercial Lines Manual)

Why classification accuracy matters: Incorrect classification inflates your premium when codes overstate your hazard level, and riggers audit penalties when they understate it. For concrete contractors, verifying your classification annually is one of the most effective cost control measures available.

What questions should Concrete Contractors ask before binding Inland Marine?

Before you bind your inland marine policy, ask your advisor these questions to ensure the coverage actually matches your concrete contractors operations:

1. Is this occurrence-based or claims-made? For concrete contractors, occurrence-based coverage provides broader long-tail protection. If claims-made, confirm the retroactive date covers all prior work.
2. Does completed operations coverage extend for the full statute of repose? For concrete contractors, claims can surface years after work is finished.
3. Are additional insured endorsements included by blanket or must each be scheduled? Blanket AI (CG 20 10) is more efficient for concrete contractors with multiple clients.
4. What is the aggregate limit structure? Per-project aggregates (CG 25 03) prevent one large claim from consuming the limit for all your projects.
5. Does the carrier have a dedicated claims team for your industry? Specialist claims handling resolves concrete contractors claims faster and at lower cost.

How do you build a complete insurance program around Inland Marine for Concrete Contractors?

Your inland marine policy is the foundation, but concrete contractors need additional coverage lines to eliminate gaps:

Workers compensation handles the employee injury claims that inland marine excludes. Commercial auto covers the vehicle liability that inland marine does not. Umbrella liability provides excess limits above your inland marine, auto, and mployers liability. And depending on your operations, you may need professional liability, cyber insurance, or pollution liability to address exposures that no amount of inland marine coverage can reach.

The most common mistake concrete contractors make is buying inland marine in isolation without coordinating the surrounding coverage lines. Coverage Axis evaluates your full risk profile and builds all lines together.

Inland Marine Rating Factors for Concrete Contractors

At the industry level, your NCCI 5022 (Masonry — including concrete work) and 5213 (Concrete construction — NOT buildings) WC classification and ISO GL class code 91580 (Concrete contractors) GL classification set the base rate. At the individual level, your (Source: NCCI, ISO)
