The Quikrete Cos. provided Quikrete Fiber-Reinforced Shotcrete MS for a river restoration in Washington state. The material was used to fill channels and create weirs to help return the Spokane River to its natural flow pattern in downtown Spokane, Wash. Prior to the restoration, that section of the river was mostly empty during hot, dry months because of manmade channels dating back more than a century.
The undulating riverbed is 150 feet deep and 300 feet wide in some areas, so the Quikrete Shotcrete MS was pneumatically pumped dry through a hose to each predetermined weir location, in some cases more than 500 feet. Water was then added to the mix at the nozzle during the spray application process.
In addition, the shotcrete was customized to match the color, texture and shape of the natural basalt riverbed as well as the surrounding geology and landscape.
The American Society of Landscape Architects recognized the restoration with an award in 2012.
