Workmen operate prepakt grout equipment as they pump grout into prepakt areas at the base of the right training wall. Equipment shown here includes, at top, two double-drum grout mixers; center, two F.S. Simplex pumps; and bottom, four triplex grout pumps with hose connections. This work was performed by the Pacific Bridge Company, as part of their contract to repair the spillway bucket section of Grand Coulee Dam. - March 1949 photo
