REVOC Tensioned Covers


Tensioned covers use weighted cables to maintain tension in the cover.

REVOC Tensioned Floating Covers use cables attached to tensioners to control slack as the cover moves up and down. This eliminates sumps on the cover surface making cleaning and maintenence much easier. The tension from the cables permits people to safely walk on the cover for periodic maintenance. The flat surface of the cover lets precipitation drain more easily and resists damage from ice. The REVOC Tensioned Cover system is ideal for covering drinking water, preventing contamination, evaporation, and minimizing chemical disinfectant addition. REVOC Tensioned Covers can also be used for waste water where they prevent algae blooms, reduce odor, and prevent dilution with rain water. Layfield can assist you in all aspects of floating cover design including design, construction, cleaning, disinfection, and maintenance services.

Layfield has been involved with many types of floating cover projects, generally either design/build arrangements, or building to the owner’s own engineered design. Each floating cover project offers its own set of challenges and opportunities, due to the unique set of conditions found on each site. A design/build relationship which involves Layfield’s input from the beginning, and which includes a signed design by a Professional Engineer, may offer the best solution to your floating cover needs.

Layfield’s REVOC Tensioned Cover designs, installation techniques, and inspection/maintenance protocols fully meet the requirements of local regulations, such as the AWWA D130 and M25 Lining and Floating Cover Guidelines and AWWA California-Nevada Reservoir Floating Cover Guidelines (1999).
