Most recently, LRutt worked on an upgrade to an active dam concrete spillway surface near Vancouver, BC, Canada. The challenges here were installing a wet mix with silica fume and steel fibers to an existing prepared spillway face up to 131 ft (40 m) high. The spillway surface shotcrete averaged 6 in. (150 mm) thick and had to be placed from a custom swing stage on elevated rails above the finished shotcrete surface profile. The spillway profile varied from 38 degrees off vertical to near horizontal. The tolerances of the finished face of the shotcreted profile was one of the many project challenges. Other hydro projects include penstock shotcrete repairs. Mining Underground In mining, some of the shotcrete projects LRutt has worked on include portal stabilization work and mine tunnel abandonment. For the latter, LRutt produces shotcrete and concrete plug installations as well as providing drilling and grouting services. Experience Advantage LRutt has diverse shotcrete project experience.
