Channels - Overview
Superior has completed many channel and canal lining projects. We offer a full range of services for new construction and rehabilitation and can take a project from beginning excavation or dredging to completion with our cost saving and time saving methods. Whether we are working on a channel for flood control, general water supply or irrigation supply, we have the skills and technology to work with challenging situations. Our innovative solutions address terrain, wet condition and environmental challenges with all of the resources that one would expect of the industry leader.
Hilo Channel: Hilo, Hawaii
The repair of this flood control channel presented remote access, environmental sensitivity and wet conditions issues. Acting as the general contractor, we completed all phases of this challenging project including 12,000 cubic yards of in-stream dredging within the Wailoa Channel requiring special water diversions during wet weather. Over 3,000 cubic yards of Shotcrete were placed on steep embankments and the severely eroded invert. Additionally, 4,500 cubic yards of concreted boulders were placed as well as specially constructed rock stack walls. The use of Shotcrete in lieu of CIP eliminated time and costs associated with conventional cast in place techniques. Shotcrete was the preferred solution because of its application in areas with tight access constraints and its adaptability is perfectly suited to radius, corner, and curved designs.
Kern County Water Agency Channel: Bakersfield, California
Within a very limited 10-week period, Superior replaced an existing 2-mile long channel lining and raised the limits of this irrigation supply channel by 8 vertical feet. Serving as the general contractor, we performed the removal, re-compaction and replacement of the existing deteriorated concrete liner. We constructed 20,000 cubic yards of new embankment and installed in excess of 2500 cubic yards of Shtocrete for the channel raising. Shotcrete again proved to be an economical choice, saving both time and money and allowing the channel to be reopened within a short time frame.
Tehachippee Bay Channel: Kern County, California
The major challenge on this project was the requirement for a speedy installation during inclement weather conditions. Superior’s vast manpower and equipment resources allowed us to gear up and perform a 24/7 operation even through the winter holiday season. The new lining for this water supply channel was constructed for the California Water Resources Board and the Kern County Water Agencies and required the application of ________ cubic yards of Shotcrete. Superior’s ability to man-up, tool-up and perform in challenging weather conditions resulted in an on time and on budget installation.
Coachella Water District Channel: Coachella Valley, California
The sandy terrain in this desert setting has made the new construction of this flood control channel particularly challenging. With its skilled crews, Superior has met the challenge and installed the rebar and 6 inch thick Shotcrete for many sections of the Whitewater River channel lining and the cut-off walls. The Shotcrete Advantage is much quicker and eliminates the need for forms and vibration techniques that could pose major problems against the sandy conditions and steep slopes. Over the years, Superior has installed several thousand cubic yards of Shotcrete on this project.
