Stoneworks Architectural Precast

What Stoneworks Architectural Precast does

Stoneworks Architectural Precast, founded in 2005 and headquartered in Elk River, Minnesota, is a custom manufacturer of architectural precast, cast stone, GFRC (Glass Fiber Reinforced Concrete), and precast concrete products operating from a 20-acre campus with two manufacturing facilities, an office, and a showroom approximately 30 miles north of Minneapolis. The company produces an extensive product portfolio across eight categories: commercial and residential architectural elements (window sills, columns, panels, lintels, surrounds, banding, cornice, balusters, keystones, quoins, medallions), historic restoration profiles, specialty items (fireplace surrounds, countertops, outdoor living), highway infrastructure, landscape elements (seat walls, planters, fire rings), site furnishings, DOT/utility products (light pole bases, equipment pads, solar panel pads), and DNR/private use products (boat ramp planks). Manufacturing relies on CNC-based custom form building, custom mix designs using varied cements, aggregates, and surface finishes, and a quality program anchored in ASTM C1364, the Cast Stone Institute Plant Certification Program, and NPCA Quality Control Procedures, with independent testing by American Engineering & Testing.

The business serves architects, general contractors, home builders, and specialty contractors across the Upper Midwest, with named projects including the UND Memorial Union, Guardian Building, The Nordic, Mount Curve, LNR Properties, and Garrison Landing. Stoneworks is one of only 27 Cast Stone Institute Plant Certified manufacturers in the United States and is also NPCA Certified Plant and MnDot Certified, supporting preferred specification status with architectural firms and qualification for transportation infrastructure work. The leadership team averages over 25 years of industry experience, and the company offers an industry-leading 10-year limited warranty on its certified output.

The revenue model is project-based custom manufacturing: each order is quote-priced based on profile, dimensions, materials, and finish specifications, with sales conducted directly to architects, contractors, and builders via a sales-led GTM motion that includes design assistance, field measuring, and value engineering. Distribution is regional direct sales supplemented by a showroom and plant tour program. The company is privately held under a partnership structure (Kirt O'Konek as President/Partner, Todd Plaisted as Vice President/Partner) and is operationally aligned with the Plaisted Companies ecosystem, which provides logistics, complementary products, and shared back-office functions.
