Pad can either be poured on site or precast by Alpha Technologies.
All dimensions shown in inches. Mounting holes and sweeps indexed from front left mounting
stud or insert.
Alpha recomends a minimum distance of 6” from the enclosure wall and the edge of the pad.
All mounting hardware must be stainless steel, galvanized steel, or better to prevent corrosion.
A 25+ year continuous vapor barrier must be used between the enclosure and the pad to prevent
moisture ingress and possible corrosion caused by metal to concrete contact. The vapor barrier
material (such as 30 lb felt, neoprene pond liner, or heavy grade tar paper) must be initially
extended at least 6" in all directions around the perimeter of the enclosure. After the enclosure is
secured to the pad, the material can be cut closer to the enclosure, using the appropriate knife or
cutting tool (see page 17).
