Some
130,000 sf of lining material was spread across the reservoir's
floor and wedge welded to create one enormous panel. Kuiper
has a tilt-up concrete roof supported by 60 columns and pilasters.
Bases
of the columns and pilasters measured 4'9", while the
columns themselves were 12-in. square. |

The
liner material had to be cut precisely, manuevered and manipulated
to fit and attached to the base of each column to maintain
the integrity of water containment. This attachment was acheived
using stainless steel batten, Sikaflex 1A, 1/4-in. neoprene
sponge and 3/3-in. stainless steel wedge-type anchor bolts.
The
stainless steel batten strips were attached to the concrete
by inserting stainless steel anchor bolts into the concrete,
placing the geomembrane over the anchor bolt, placing a strip
of neoprene gasket between the liner and batten strip and
securing the batten strip with washers and nuts. |

A
12 oz non-woven geotextile (manufactured by TNS Mills) was laid
out over the existing asphalt base to cushion the liner from the
weight of the water on any sharp surfaces on the asphalt that might
cause punctures or abrasions.
Some
130,000 sf of lining material was placed across the reservoir floor
for final wedge welding.
After
installation (we finished 3 weeks early and on budget), the liner
was inspected, washed and the Kuiper Reservoir was refilled and
once again, through teamwork, was serving its community. |
