Third-generation family ownership ensures continuity in quality and service. We specialize in Smooth Standard Units, Architectural Splitface & Groundface Units, Allan Block, Stonewall Retaining Wall Units, and Chimney Block.Our product range expanded in 2025 to include precast materials like Parking Bumpers, Drywells, and Septic Tanks. We also supply masonry accessories including tools, cleaners, and sealers. With 79 years of continuous operation, we serve the Inland Northwest from our Spokane, Washington facility. Our public hours reflect our commitment to accessible, hands-on customer service. This legacy of innovation and family stewardship drives our ongoing contributions to regional construction projects.
