FITTING THE WATERPROOFING MEMBRANE
8.1
Installing the liner locking track
Before starting to install the liner locking track, make sure that the structure has been correctly assembled.
To do this, check that the entire periphery is horizontal (use a spirit level), and that the diagonals are equal
in length. If not, rectify these imperfections before continuing.
Start installation of the liner locking track in a corner, as shown in
of the pool, taking care with the joins between each 1.18 m length of track. Each section of track must
be perfectly aligned with the two adjacent sections of track to avoid damaging the liner. Joins between
sections of liner locking track do not need to coincide with the structure's supporting braces.
It may be necessary to trim the track at the end of a
length or width: to do this, measure the distance to
be covered and cut a bar to that length. Remember
to deburr the track after trimming.
The track should be flush with the top of the wooden
structure. Before fixing the liner tracking track into
position, pre-drill the track using the 4 mm diameter
drill bit provided (bag J). Insert the screws provided
at approximately 20 cm intervals (A4 SS torx
countersunk screws 4 × 35 threaded over 20 mm,
bag H). Do not overtighten, to prevent screws from
passing completely through the rail.
8.2
Applying self-adhesive gaskets
If you deferred application when the part was fitted to delay laying of the waterproofing membrane
(paragraph 7.1, page
25), glue the gaskets onto the skimmer and the return fitting.
Make sure that the gaskets are correctly positioned and applied. It will be difficult to rectify an omission
or mistake after the liner has been fitted. Check that the holes in the various pool fittings (skimmer,
return fitting) and the holes in the wooden wall are correctly aligned with the holes in the gaskets.
8.3
Fitting the underlay
Remove and defects or debris before spreading the underlay out over the slab.
The underlay is cut to the dimensions of your pool and does not need to be trimmed. Make sure that the
underlay covers the bituminous strips. Smooth out wrinkles as much as possible before laying the liner.
8.4
Fitting the water proofing membrane (liner)
B efore fitting the waterproofing membrane (liner), make sure that the surfaces are free of splinters or
any other surface defects that could damage the liner.
Ensure that all the gaskets have been correctly applied.
The ideal temperature for fitting a liner is between 18 and 25°C.
Put the liner pack in the pool (take care, the liner is very heavy). Remove the liner and unfold it across the
pool width (see
Figure
rest for a while at ambient temperature (between 18 and 25°C) so that it becomes more supple and easier
to fit.

27) then down the length. Before starting to actually fit the liner, allow the liner to
continue around the periphery
