Water Tank Liner Installation Guide
Check both the inside of the tank as well as the rim of the outside of
the tank for any sharp or protruding objects that can either damage or
puncture your liner. The Geotextile protection underlay should help
protect the liner as much as possible when it is dropped over the top of
the tank. There are two ways to secure the tank liner installation,
depending on the type of tank you have. With open top tanks, the liner
is folded over the edge by about 150 mm and secured around the outside
with wire (in the case of corrugated tanks).
Carefully unroll the liner on the tank floor and open the liner up,
making sure that the centre of the liner (marked with 300mm diameter
circle) is exactly in the centre of the tank. Take care when unfolding
the liner and ensure that you unfold each fold one at a time. Make sure
that the wall to base seam (the welded seam that continuously goes all
the way around the tank) is pushed up against the floor/wall juncture
(where wall meets the floor of the tank).
