RCP Block & Brick in Chula Vista has manufactured and supplied masonry and hardscape products since 1947, operating the North Fourth Avenue yard as one of seven retail locations spanning San Diego and Riverside counties as one of seven retail locations. The Chula Vista location stocks the same decomposed-granite, flagstone, and boulder inventory specified by hardscape contractors at Southwest Boulder & Stone, creating a two-source supply chain for large-format residential patio and retaining-wall projects near the Broadway corridor. Product lines include the proprietary Bella Vista Hardscape Collection of concrete pavers, landscape wall block, and retaining-wall systems, plus architectural CMU block, brick, stone veneer from Cultured Stone and Eldorado Stone, decorative landscape rock, sand, gravel, and outdoor-living kits for fire pits, fireplaces, and BBQ islands. Architects designing masonry-intensive commercial and residential projects in Chula Vista specify RCP products on construction documents, and design firms including Luis Davalos Design reference the company's architectural CMU color and texture samples during the schematic-design phase. The manufacturing division produces custom-color integral-pigment CMU block in split-face, ground-face, and burnished finishes, with compressive-strength ratings certified to ASTM C90 at a minimum 1,900 PSI net-area average for structural load-bearing applications.
