Deschutes: Canal-Lining Demonstration Project Durability Report. Year 2
The Deschutes Canal Lining Demonstration Project is a cooperative effort among the Bureau of Reclamation, the Oregon Water Resources Department, Deschutes River basin irrigation districts, and geosynthetic lining manufacturers to develop low-cost canal-lining technologies to reduce seepage over severe rocky subgrade conditions. The 18 test sections include combinations of geosynthetics, soil, concrete grout, shotcrete, elastomeric coatings, and sprayed-in-place foam. This report assesses the durability and documents the maintenance requirements after two years of service. Obvious differences in the performance of the test sections are becoming apparent. The two exposed coated geotextile test sections have washed out completely; the two sprayed-in-place polyurethane foam test sections have partially washed out and need extensive repairs; and the two exposed geomembrane test sections with grout-filled mattresses on the sideslope are experiencing uplift pressures and are in danger of failure. The other 12 test sections (consisting of shotcrete, grout-filled mattresses, or exposed geomembranes) are in very good to excellent condition. Some test sections are in need of minor repairs at this time. If not repaired promptly, these minor problems may develop into major problems requiring expensive repairs, and may even lead to premature failure.
