Construction Sand and Gravel Mining
NAICS 212321 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in one or more of the following: (1) operating commercial grade (i.e., construction) sand and gravel pits; (2) dredging for commercial grade sand and gravel; and (3) washing, screening, or otherwise preparing commercial grade sand and gravel.
Start the review with heavy equipment liability.
For Construction Sand and Gravel Mining, the saved research highlights heavy equipment liability, workers compensation, environmental and pollution liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- How many pits or extraction sites are operated, and in which states?
- What is the composition and size of the haul truck and heavy equipment fleet?
- Are any dredging operations conducted, and if so, in what type of waterway?
- Are there any processing plants, wash plants, or conveyors on site, and what are their replacement values?
- Has the operation received any environmental citations, stormwater violations, or reclamation orders?
- What is the prior five-year loss history across workers comp, auto, and GL?
- For Construction Sand and Gravel Mining, what should the underwriter know about prior environmental citations, reclamation orders, or stormwater violations?
- For Construction Sand and Gravel Mining, what should the underwriter know about dredging operations in navigable waterways or jurisdictions with heightened environmental oversight?

Construction sand and gravel mining operations typically involve excavating open pit or dredging operations to extract raw aggregate material, followed by washing, screening, and sorting to produce construction-grade products sold to contractors, concrete producers, and road builders. Day-to-day activity centers on heavy equipment operation, haul truck movement on and off site, and stockpile management across large outdoor acreage.
