OPTIMUM ROUND ABOVE / IN-GROUND POOL
Section 1
Step 9 - Install Concrete Collar
9.1
IN-GROUND ONLY:
All pools that are buried more
than
24”
below
grade
require
a
concrete
collar, 12”
wide
by 8”
high, around
the
entire
perimeter
of the
pool. If
extra
supports are required for patio or other pool features,
consider installing them before pouring the concrete.
If the pool is installed into a hill, as illustrated in image 9.2,
the pool
still
requires a concrete collar
12”
wide by 8”
high
at any location
where
the
pool
is buried
more
than
24”
below grade. Taper the ends of the concrete collar once
the
depth
below
grade
becomes less than
24”.
