Abstract: Precast charging station pads comprising a base, a first barrier attached to the base, and a conduit chase extending through the base. A method of installing a precast charging station pad having a base, one or more barriers, a conduit chase, and lifting pins, the method comprising digging a hole at least 6 inches wider in each direction as the precast charging station pad, filling the hole with sufficient crushed stone so that the precast charging station pad will be level with a final grade, installing a conduit, placing the precast charging station pad over the conduit using lifting pins, backfilling soil around the precast charging station pad, and compacting the soil.

Abstract: An assembly of precast concrete units matingly assembled on top of one another to form a whole deck footing, capable of supporting a deck, shed, porch, addition or other structure. The individual units are of manageable weight and can be moved by one person, not unlike a bag of unmixed cement. The units interlock to prevent shifting, separating, frost damage by water infiltration and heaving when placed under ground.
