Project
Rehabilitation of lake-to-lake equalizer
control pipe
Client
Georgia Department of Natural Resources
Location
Tifton, Georgia
Description
Vertical overflow control pipe structure is located approximately 18 feet inside the lake in Tifton, GA with problems of deterioration and infiltration. Infiltration was impossible to stop with cement or chemical grout. Numerous attempts had been made to solve the problem, with no success.
Solution
Working from a barge, the Poly-Triplex Liner was installed. The liner was inflated with air pressure sufficient to hold back the hydrostatic head pressure until the liner was cured-in-place and bonded to the host structure. Installation was complete, start to finish, in one day. The Poly-Triplex Liner completely stopped the infiltration and ex-filtration as well as further deterioration.
Benefit
This method of repair resulted in considerable cost savings over other methods of construction, as other repair methods previously attempted were unsuccessful.
