No Diving or Jumping.
Observe all Safety Rules.
7. Strap Preparation for the Buttresses
a.
Gently
flatten any kinks or bends out of the straps (key 8).
b. Lay the strap across the lev-
elled area for the pool as
shown in diagram 30. Centre
the strap over the patio stone
as shown in diagram 30.
Space the end of the strap
2-1/4" (6 cm) from the outside
edge of the patio stone.
c. Fasten one diagonal bracket
(key 16) to the strap (key 8)
using four 3/4" long bolts (key
21) and nuts (key 10). Make
sure the angled part of the
bracket is facing the correct
direction as shown in dia-
gram 32. The surface that the
diagonal bracket is fastened
to will be the top of the strap.
d. Repeat steps (a) to (c) for the
other end of the strap.
e. Repeat steps (a) to (d) for the
other straps.

Hint:
Crushed lime-
stone
or equiva-
lent
must
be used
instead on brick
sand or
vermiculite to
backfill the base
channels. The
level of
compaction
achieved by using
crushed limestone
or equivalent is
superior to that of
brick sand or
vermiculite.
Caution:
Brick sand or
vermiculite
cannot
be used on any
part of the buttress
installation proc-
ess. These materi-
als have poor
compaction prop-
erties that can
cause problems
with the buttresses
after the pool has
been filled with
water.
