Process for lowering basement
 In the construction of a building in which a basement is prefabricated on the ground and then lowered into the ground by excavating soil below the basement, a process for lowering the basement comprises: driving corrugated steel plates into the ground around a region in which the basement is to be installed; applying an adhesive on a surface of the basement adjacent to the steel plates; applying a lubricant on a surface of the steel plates adjacent to the surface of the basement; forming in-situ a flexible and resilient material in a space between the surfaces of the basement and the steel plates, the material serving as a guide member which is bonded securely to the basement; excavating soil below the basement; and causing the basement to descend into the ground.
