4 holding the CSLB C-8 Concrete · 4 with active workers' comp
A CSLB C-8 Concrete classification covers the foundations, footings, and flatwork under patios, driveways, and retaining structures. On California's shrink-swell clays, that base work is what keeps a patio from heaving — so a C-8 holder is the contractor qualified to pour it, not just lay the surface.
