CRACK REPAIRS TO UPPER STILLWATER DAM

Upper Stillwater Dam in Utah was constructed from roller compacted concrete and completed in 1987. In 1988, during the first filling of the reservoir, a continuous crack was discovered in the foundation gallery. The Bureau of Reclamation repaired this and other similar but smaller cracks at various stations. Due to the potential for crack movement with seasonal reservoir level changes, a flexible hyrophilic polyurethane resin was selected for injection into the cracks. The selected repair procedure was to inject the crack with polyurethane resin in 3 stages. The details of these stages are described.
