2.1.2 Concrete Pad Layout
The illustration below shows the general dimensions for a poured
in place concrete pad. When placing the pad, allow at least 36
inches of clearance to allow the front and rear doors to fully
open.
3/8" diameter (4 places) bolts (which should extend
1"-1 1/2" above the surface of the pad). All mounting hardware
must be stainless steel to prevent corrosion.
A 25+ year continuous vapor barrier must be used between the
enclosure and pad to prevent moisture ingress and corrosion
caused by metal-to-concrete contact. The vapor barrier material
(such as 30 lb. felt, neoprene pond liner, or heavy grade tar
paper) should initially extend at least 6" in all directions around
the perimeter of the enclosure. After the enclosure is in place, the
material should be cut closer to the enclosure, using the
appropriate knife or cutting tool.
