Pads can either be poured on site, or precast by Alpha Technologies. The mounting

holes on the bottom of the side car will fit both a standard PN-3 pad, and a CE3X pad.

Precast pad model number PCD-SC-3X, Alpha P/N 641-064-10 is available for this

system.

2.1

Concrete Pad Preparation

2. Installation

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.
