You can now spread approximately 10 cm (4") of compacting sand
all around the inside base of the wall in order to protect the liner
from the cutting edges of the bottom tracks and the stone dust (if
applicable), or install a prefabricated cove if available.
SAND BASE FINISHING
Level finishing sand one last time. Make sure that any sharp stones,
debris or roots have been removed from the surface. For better pro-
tection, spray sand with water and pack it once more until the base
is nicely even.

Before pulling the liner up against the wall, insert a vacuum cleaner
hose down into the pump return hole to approximately 15 cm (6")
from the ground.

Maintain the hose in place with adhesive tape. Don't forget to block
the skimmer hole with adhesive tape to prevent air from leaking in.
Place the unfolded liner in the center of the pool area at right angles
with the skimmer hole. Make sure you wear light, flat-soled shoes
to walk on the sand as the slightest heel mark could be visible once
the pool is filled.

SAND COVE
(or PREFAB COVE)
Carefully unfold the liner, bringing the bottom-sidewall seam close
to the wall base. Make sure that the side with the protruding seams
faces downward or that the patterned side faces upward.
Lift up a section of the liner over the top of the wall leaving a 10 cm
to 15 cm (4" to 6") fringe outside the wall. Secure the liner with a
plastic coupler (sold separately). Install the top track on the wall
then install the top plates on top of each upright.
At this point, the liner may be too tight, making it difficult to drape
the overlap or, on the contrary, too loose. In such cases, you will
have to redistribute the tension in the liner by removing some of the
couplers and readjusting the liner.
