5 holding the CSLB C-29 Masonry · 5 with active workers' comp

A CSLB C-29 Masonry classification covers structural block, stone, and segmental retaining walls. Any wall over four feet (or bearing a surcharge) is engineered work: a C-29 holder is licensed for the drainage, reinforcement, and footing that stop a wall from bulging or failing — the difference between a wall that lasts and one that leans.
