remaining pool walls with rigid foam insulation. See Figure 4.9
and 4.10. We would strongly recommend insulating the walls of
the pool. Please note that the insulation boards should not be
used under the pool as the anchoring system will be compro-
mised. Insulation under the pool has only a marginal value, as
the heat transfered is not lost. If you wish, with new construc-
tion, you may lay down rigid foam insulation prior to pouring
the concrete slab.
5. Optional Tension Straps for Flat Bottom Pools
When the deeper pool option has not been selected and it is
desired not to drill into the concrete floor, Tension Straps may
be used. See Figure 5.1. These are ordered from Endless Pools,
Inc. for any size pool. The kit for a standard 7' x 14' pool con-
sists of 4 stainless steel tension straps, 1 long (14' 7") and 3
short (7' 7"). These straps run under the bottom flanges and
along the floor, connecting to the outside lips of the flanges on
each side (Tech Bulletin #2, page 3). See Figure 5.2. They are
designed to resist the hydrostatic force of the water in the pool.
Assemble the panels as described above placing the Tension
Straps under the bottom flange. The vertical lip of the bottom
flange of each panel has pre-punched holes to accept the 3/8"
nuts and bolts which are used to secure the tension straps. See
Figure 5.3. This is the same hardware used to bolt the panel
enclosure together. The Tension Straps should connect between
the centers of opposite panels and at the joint in the long walls.
Tighten the nuts and bolts securing the tension straps before
sliding the pool into a corner. See Figure 5.4. If a strap bows up
check the dimension of the pool enclosure at the bottom as the
panels may be bowed in. If necessary, you may loosen a tension
strap bolt on the accessible end of one tension strap and pull the
strap taut. Be sure to keep the nut and bolt in place and tighten
them as you fill with water and the panels push outward.
