What White Block Company does

White Block Company, Inc. is a privately held, third-generation family-owned concrete masonry manufacturer and building products distributor headquartered in Spokane Valley, Washington, founded February 20, 1947 by twin brothers Edward and Harold White. The company operates a 10-acre manufacturing facility running a Besser V12 machine capable of producing over 28,000 concrete masonry units per day across more than 200 block SKUs, including smooth standard units, architectural splitface and groundface units, Allan Block and Stonewall retaining wall units, chimney block, specialty block, and the proprietary patented Wall Drain Pro drainage system. In addition to in-house manufacturing, White Block distributes a broad complementary product portfolio: Allan Block retaining wall systems (AB Classic, AB Ashlar, AB Europa, AB Stones, AB Three, AB Junior, AB Metro, AB Courtyard, AB Metropolitan, AB Fence), Boral Cultured Stone, Selkirk Stone, and Telluride Natural Stone veneers, Willamette Graystone and Abbotsford pavers, Big Rock Block wet-cast gravity wall blocks, precast infrastructure products (septic tanks, drywells, catch basins, water storage tanks up to 3,000 gallons, window wells), and masonry accessories (PROSOCO cleaners/sealers, Quikrete, Hubbard Jointers tools). The company serves the Inland Northwest region (Spokane Area, Eastern Washington, North Idaho, Western Montana) through direct sales at its Spokane Valley facility (open to the public weekdays) and a regional dealer network of approximately 28 locations, targeting five primary customer segments: homeowners/DIY, landscape contractors, masonry contractors, excavation contractors, and commercial/government projects. Pricing is quote-based on project specifications, with delivery available for additional charge, and Allan Block Contractor Certification classes are offered as a channel-enablement and training service.

Direct peers

• Mutual Materials: Mutual Materials is the largest masonry and hardscape manufacturer and distributor in the Pacific Northwest (headquartered in Bellevue, WA). Both companies manufacture concrete masonry units, distribute pavers and retaining wall systems, and serve overlapping PNW contractor/dealer networks, making it the most directly comparable regional competitor.
• Basalite Concrete Products: Basalite is a western U.S./PNW manufacturer of concrete block, hardscape, and retaining wall products. It directly competes with White Block on standard and architectural CMU, segmental retaining walls, and pavers for residential and commercial construction in the Inland Northwest.
• EP Henry: EP Henry is a family-owned concrete masonry and hardscape manufacturer in the Mid-Atlantic U.S. producing concrete block, pavers, and segmental retaining walls. It is a comparable business model (multi-generation family ownership, regional manufacturing, full masonry/landscape portfolio) operating in a different geography.
• Block USA: Block USA is a regional concrete block and masonry manufacturer operating multiple plants across the southeastern U.S. Its business model - regional CMU manufacturing, hardscape distribution, and dealer/contractor channel - mirrors White Block's structure at a larger multi-site scale.

Others

• Allan Block Corporation: Allan Block is the manufacturer of the namesake segmental retaining wall systems (AB Classic, AB Stones, AB Three, etc.) that White Block distributes exclusively in the Inland Northwest. It is also a co-development partner that runs the contractor certification classes that White Block hosts - a strategic partner/supplier rather than a direct competitor.
• Boral Cultured Stone: Boral (now part of Westlake Royal) is the leading manufacturer of manufactured stone veneer in North America and a key distribution partner of White Block. It is comparable as a strategic supplier/brand that competes for the same stone-veneer wall budgets in the PNW and across the U.S.

Broad incumbents

• Quikrete: Quikrete is the largest packaged concrete and masonry products manufacturer in North America, including concrete block and hardscapes. White Block is also a Quikrete distributor (stocking Fast-Setting Concrete Mix and Countertop Mix), making Quikrete both a supplier and a broad incumbent competitor across the masonry value chain.
• Oldcastle APG: Oldcastle APG (CRH plc) is the largest manufacturer of concrete masonry, hardscape, and retaining wall products in North America. Its scale, national dealer relationships, and product breadth make it the highest-impact potential entrant into the Inland Northwest market where White Block competes.
• Pavestone: Pavestone is a large national manufacturer and distributor of segmental concrete pavers and retaining wall systems serving landscape, masonry, and DIY channels. Its product overlap with White Block's paver and Allan Block retaining wall offerings makes it a directly relevant broad incumbent in the hardscape category.
• Techo-Bloc: Techo-Bloc is a North American manufacturer of premium concrete pavers, retaining walls, and outdoor living products. While premium-positioned and brand-led, it competes for the same hardscape and retaining wall budget that White Block's Allan Block, paver, and outdoor living lines target.
