A prefabricated service bay typically constructed of fiberglass has a tank-like profile with an access opening for providing access to the underside of a vehicle. The prefabricated service bay is placed within an excavated hole within a vehicle service stall. The tank has a rounded section normal to the longitudinal axis of the bay. Drainage fill, such as pea gravel, is used between the bottom portion of the excavation and the bottom portion of the tank. A concrete cap is poured and cured over the top portion of the tank adjacent the opening. This poured and cured concrete serendipitously forms paired tracks for rolling placement of the wheels of a vehicle being serviced and additionally serves to key and maintain the service bay within the ground. Provision is made to provide a central standing area－preferably in the form of a raised platform－in the center bottom portion of the tank. Entrance and exit to the bay is provided through an end passageway with optional side staircase entry. Required accessories for material storage and the capture of fluids can be integrally built into the interior of the prefabricated unit. When installed, the service bay forms the required outer tank lining of a regulation required double lining system for oil storage underground.

An underground service bay placed within the ground comprising: a prefabricated unit for placement in the ground including a cylindrical tank body having a major axis of the cylindrical tank body parallel to a longitudinal direction of the underground service bay; an access opening defined in an upper portion of the cylindrical tank body for exposure to a vehicle underside, the access opening having a width relative to the longitudinal direction of the underground service bay to occupy less than a diameter of the cylindrical tank body to enable the cylindrical tank body to have paired upwardly exposed tank sides on either side of the access opening; the cylindrical tank body having a arcuate cross section normal to the major axis of the cylindrical tank body to provide an increased diameter below the access opening; paired spaced apart vehicle supporting tracks defined over the upwardly exposed tank sides of the cylindrical tank body adjacent the access opening; means for holding the prefabricated unit to the ground including a cap maintaining the cylindrical tank body within the ground against buoyant forces acting on the prefabricated unit.
