ABSTRACT:
A removable temporary flood protection device which, when installed in a building doorway, provides a substantially water-tight barrier to entry of flood water through the doorway opening. The flood protection device includes an inner water resistant rigid core and an outer inflatable flexible seal tube. The inner core has a bottom and spaced apart sides which respectively extend generally parallel to the doorsill and door jambs of the doorway and are spaced upwardly and inwardly thereof so that the inner core extends across a lower portion of the doorway opening and thereby providing partial closure thereof except for a narrow space defined between the bottom and sides of the inner core and the doorsill and door jambs of the doorway. The inflatable seal tube is attached to a top of the inner core and extends down along the spaced sides and across the bottom thereof so that the seal tube is located in the narrow space defined between the inner core and the doorway. Once inflated, the seal tube is disposed at its inner side in sealing contact with the bottom and sides of the inner core and at its outer side in sealing contact with the doorsill and door jambs of the doorway thereby forming a substantially water-tight seal in the narrow space defined between the inner core and lower portion of the doorway opening for completing closure thereof.
