The one-piece body further comprises a hollow riser section having an upper portion defining an opening, and a lower portion, the riser lower portion extending upwardly from the base member upper portion, the riser section having sidewalls with a generally corrugated shaped cross section in an axial direction. The hollow base member has a bottom and sidewalls, each of the bottom and sidewalls having an outer surface. The base member is fiberglass encapsulated, which encapsulation comprises a fiberglass woven reinforcement pad layer disposed on the base member bottom outer surface; a chopped fiberglass material layer disposed on the sidewalls outer surface up to and including an area abutting the riser section lower portion; a polymeric coating material layer disposed on the fiberglass woven reinforcement pad layer and the chopped fiberglass material layer; and a polymeric sealant material layer disposed on a portion of the riser section lower portion and on a portion of the polymeric coating material layer, at the area abutting the riser section lower portion.
