When
Kuiper Reservoir was constructed in 1967, a lining system
consisting of an asphalt base and a membrane liner was installed.
That system was replaced in 1978 with a polyurethane in liquid
form that was sprayed onto the surface of the existing asphalt
to create a seal and liner was put in place over the polyurethane but
begain failing within three years and it was repaired yearly
until the failure rate exceeded the repair rate.
Engineers
in the Aurora office of Black & Vetch researched many
options for replacing the lining. Cooley Engineered Membranes
was selected to provide the base lining material and Colorado
Lining, as a certified fabricator and installer of Cooley's
materials was selected to begin the process of fabricating
the polypropylene into panels to fit and install in the reservoir. |
