About the C-8 — Concrete License
The C-8 Concrete license authorizes contractors to mix, pour, and finish concrete for a wide range of residential and commercial applications. This includes foundations, driveways, patios, sidewalks, retaining walls, and decorative concrete work like stamping and staining. Concrete is one of the most versatile and durable building materials, and proper installation requires significant skill and experience. Factors like mix design, reinforcement, curing conditions, and finishing techniques all affect the final product's strength and appearance. California's seismic requirements add another layer of complexity, particularly for foundation work. When hiring a C-8 contractor, ask about their experience with your specific project type, the concrete mix they recommend, and how they handle weather-related scheduling challenges.

What does a C-8 Concrete license cover?
A C-8 license covers all concrete work including mixing, forming, pouring, and finishing. This includes foundations, slabs, driveways, patios, sidewalks, retaining walls, and decorative concrete like stamped and stained finishes.
How long does concrete take to cure?
Concrete reaches about 70% of its strength in 7 days and full strength in 28 days. However, you can typically walk on it after 24-48 hours and drive on a driveway after 7 days. Your C-8 contractor will advise on specific timing for your project.
Do I need a licensed C12 contractor in California?
Yes. California law requires a licensed contractor for any c12 work valued at $500 or more. Licensed contractors must pass exams, maintain bonding, and carry insurance. Hiring unlicensed contractors puts you at risk.
