Constructing a Concrete Pad
A concrete pad provides a permanent foundation to anchor the cabinet to the ground while
protecting the cabinet from water damage and other outdoor surface conditions.
Construct a concrete foundation pad for the cabinet at the installation site. Pad construction
requires excavating the site, trenching cable conduit, constructing a form, and casting
concrete. Use the Calix-supplied cast-in-place template to provide exact locations for the
mounting studs that anchor the cabinet to the pad and to provide the cable conduit locations.
Pad Construction Guidelines
When constructing a concrete pad, observe the following guidelines and refer to the pad
drawings for additional guidance.
Guidelines
Follow these guidelines to ensure proper pad construction. Adjust for local conditions or
practices as required.
Construct the pad with minimum perimeter dimensions of 130 x 158 inches.
Construct the pad with a minimum height of 6 inches.
Construct the pad with a maximum of 2 inches above-grade exposure.
Use the Calix cast-in-place template to provide exact mounting stud and conduit
locations.
Use rebar or wire mesh inside the form to improve pad strength.
Cast the pad from a single concrete pour. Do not make multiple pours.
Use 4-inch conduit (maximum) for outside plant cables. See drawing below for entry
locations.
Use 2-inch conduit (maximum) for AC cable. See drawing below for entry location.
Include pull cords in all cable conduits.
