Abstract: A method of fabrication of an emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The shelter is preferably fabricated by vacuum forming a top sheet and a bottom sheet of ⅛ inch acrylic sheet on molds to form top and bottom sections which are then sprayed with an epoxy-fiberglass composition for reinforcement.

Abstract: An emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The unit is sealed to prevent moisture infiltration and provides the benefits of a relatively pleasant surface without the accumulation of moisture. Additional advantages are the relative lower expense, light weight, and ease of installation of the prefabricated shelter. Other uses of the shelter include security and storage.
