a. Dig a hole 48" deep and 20"x 20"square . The edge of the hole
should be flush with the edge of the playing surface. If you live in an area
where heavy frost can occur, it may pose a problem, consult your local
building inspector to determine the appropriate hole depth.
b. Build a form before pouring the concrete pad, to ensure that the top
of the concrete remains straight and square. The form should
be placed about 1/2" above the playing surface to allow for water drainage.
c. Bell out the bottom of the hole.
