Stake out the lines of the walk, or dimensions of the floor. Excavate
to a depth of 16 inches, ram and tamp the ground thoroughly and evenly
and fill in 12 inches with clean large cinders, broken stone, pebbles,
brick bats, broken tile or other material selected. Place in position
wooden forms made of 2 by 4’s, these 2 by 4’s to be set on edge and
held in position by stakes firmly driven in the ground, the top edge to
be located so as to accurately outline the established grade or slope
of the walk or floor.
A walk should be higher in the center, or at one edge, to insure the
water running off. This slope should be ¼ of an inch to the foot.
