A concrete finisher on a Sacramento commercial slab develops severe chemical burns after kneeling in wet concrete for 6 hours without proper knee protection — treatment for concrete dermatitis and chemical burns in California, including wound care and lost wages during recovery, can exceed $60,000. Cal/OSHA's Title 8 Section 1512 requires employers to provide knee protection for concrete work, and failure to do so often results in a penalty citation alongside the workers comp claim.
California's dual-wage system rewards concrete contractors who pay $24/hr or more with a significantly lower rate ($5.37/100 vs $9.80/100 for the under-threshold tier). PEO programs help concrete contractors structure their payroll to maximize the number of workers qualifying for the higher wage tier, while providing group workers comp coverage that accepts both wage tiers under a single policy.
At $5.37/100, the higher-wage tier for California concrete work is moderate — roughly 15% above the national NCCI average. This reflects California's dual-wage incentive system, which WCIRB introduced to encourage contractors to pay prevailing wages. Contractors on public works projects in California are required to pay prevailing wages under Labor Code Section 1771, which typically pushes concrete workers above the $24/hr threshold and into the lower rate tier.
