For even more variety, a 12-inch wood-plank boardwalk pattern in Sonora Tan graces the mall’s roundabout and accents selected areas. For visual breaks, an 8-inch slate border in Sand is straight in places and free-flowing in others. Throughout the concourse, a basket-weave brick pattern integrally colored with Bomanite Brick Red and a random slate pattern in Shale Gray covers much of the way. The new design called for a variety of concrete stamp patterns, colors and streetlights that would transform the mundane walkway into an interesting, winding streetscape. Like many of its ’70s counterparts, the mall featured a concourse outfitted with now-outdated colored tiles. Valley Fair Mall first opened for business in 1970. Billed as an extremely effective alternative to demolishing an existing substrate, Thin-Set also can be exposed to traffic quickly - which was a priority for this job. It typically is installed 3/8-inch thick and can be feathered to a zero edge. The Bomanite product, a specially formulated polymer-modified topping mix that can be imprinted, will bond to any stable, structurally sound substrate. “Grimbal traveled to Utah and spent about a week with us, helping us develop the Thin-Set II system and get it down pat.”Īlthough Johnson says he’s used the Thin-Set II system multiple times over various substrates, he had never before used it over existing tile.

Terry Grimbal, director of technical services for Bomanite, was key to the project’s success, as was technical input from Chris Sullivan with ChemSystems Inc., says Johnson. So Devin Johnson, the company’s vice president of technical sales and marketing, turned to Bomanite’s expertise for guidance. As one of the first 10 Bomanite franchises in the nation - it began representing Bomanite in Utah in 1978 - Architectural Concrete and Design had over the years installed a wide variety of hardscapes for commercial, residential and municipal projects, but it had never tackled the interior of a mall.
