VI.
Making a protective sand cushion at the foot of the inner pool
Diagram 29
Diagram 30
To protect the liner against the rail and the pool wall, it is recommended to create a protective covering made of fine brick sand at
the foot of the pool wall (see diagram 29 and 30). The size should be height 15 cm x width 15 cm so that it completely seals the
rail but doesn’t distort the pool liner
.
VII.
Fitting the PVC pool liner
Fit the PVC liner on a warm and sunny day, preferably above 22°C. Unfold the PVC liner and put it in the sun for 2 hours. This helps
to soften the PVC. If the temperature is below 16°C, the PVC liner will be hard and rigid and quite difficult to handle.
Put the liner at the center of the pool site inside the pool wall. Extend it evenly until the seam line reaches the base of the pool
where the protective sand cover is. Smooth out all the wrinkles in the liner. Straighten the PVC liner and hold it perpendicular to the
ground. Drape the pool liner over the pool wall.
There should be an overlap of 8 cm of the pool wall height (see diagram 31 and 32). Hold the overlap in place with clothes pegs.

Diagram 32
Check if the pool liner is placed evenly around the perimeter. Evenly fold the excessive length of the PVC if you find it a bit loose.
Check if the overlap is uniform. If the pool liner is slightly short, then you will have to let it down and vice versa.
Fill the pool with 3 to 5 cm height of water to smooth out the liner against the pool wall (see diagram 31). Check to see if water is
level, if not, something is wrong and you will have to dismantle the liner and pool wall to access and level the ground area.
