4.7.2 Smoothing any folds
If vertical folds occur on the wall part of the
liner, they can be eliminated by displacing if
a partly fixed top wall edge trim is present.
Move the folds starting from the ground outwards
toward the swimming pool wall. In particular, see to it
that the liner weld lies between the pool bottom and
wall precisely in the swimming pool bottom/wall
corner. Before filling the swimming pool with water,
the liner welds should everywhere be identically far
from the swimming pool edge and have no folds or
creases as far as possible. Since the pool liner has
been fabricated to be somewhat smaller than the
swimming pool size, so as to take account of
expansion due to the effect of temperature and water
pressure, it is imperative that the pool bottom seams
are uniformly offset from the swimming pool wall.
Following final installation of the top wall edge trim,
correction of any remaining folds on the pool bottom
can be made by filling the pool with a 2cm to 3cm
water layer and displacing the folds outwards.
If folds on the wall cannot be smoothed::
Wait for a water layer 20–30 cm thick. If the problem
persists, partly take off the trim (step by step, never
completely!) and displace the liner to the side to
reduce any folds or remove them as much as
possible. In this case the liner must be adequately
secured with the top wall edge trim to prevent the
liner from sliding down into the swimming pool. If all
those measures fail, that is, the folds are intolerably
large, the only way out is to start a completely new
attempt to install the liner.
Professional hint: A conventional vacuum
Fig. 71 cleaner can be used to smooth the sheet
around walls.
The vacuum cleaner hose mouth must be wrapped
with geotextiles (which must be fastened to the hose
with an adhesive tape) to prevent the hose from
sticking to the plastics. Push the hose end through
the opening in the skimmer and further on behind the
liner. Put a carton with a hole onto the skimmer lid
and push the hose through it and make this assembly
tight with an adhesive tape. This system will only
work if all the remaining openings, i.e. the return
nozzle holes and the skimmer holes, are blinded from
the outside with adhesive tape. Now activate the
vacuum cleaner to roughly one-half of the maximum
power. Air will start to be aspirated and the plastic
sheet with tighten slowly. What remains to do is only

to smooth out the folds arising from the sheet storage
in the box.
