Abstract
Abstract A flood barrier intended for use in conjunction with the doorways of homes. The barrier comprises a U-shaped channel structure, the legs of which are secured either to the walls of the home immediately adjacent to a door frame or to inner faces of the door opening, with the back of the U extending across the door sill. The bottoms and at least one side wall of the channels are lined with sealing strips. A panel of waterproof material has dimensions corresponding to those of the channel structure and is adapted to be fitted in the channel during flood conditions. When its use is not required, the panel is stored in an out of the way protective position, such as by being secured to the inner face of the door in the doorway which is to be protected.
