Abstract
Liquefiable soil is treated for earthquake liquefaction protection prior to erecting a building structure or work. A plurality of substantially vertical prefabricated drains are positioned at spaced intervals in the liquefiable soil and a reservoir is provided and adapted for draining off water which is expelled from the drains during an earthquake. The drains are generally comprised of an elongated plastic core material providing channels for channeling water off or therealong and this core is sometimes or selectively surrounded by a filter fabric as required to provide a composite drain.
