A flood prevention device, comprises a flexible, waterproof sheet 4 with a bottom edge 7 and two opposing side edges 8a 8b, a floatation member retained by the sheet 9, and attachments for attaching the device to a structure 5. The attachments comprise a horizontal component, and two upwardly extending support members 3a 3b which, in use, extend around a portion of an opening 6 in a structure 5. The bottom edge of tile sheet 7 is sealed to the horizontal component and at least a portion of each side edge 8a 8b is sealed to a respective support member. All seals are watertight, and in the event of a water level exceeding a predetermined height, a portion of the sheet is caused to move by floatation from an initial stowed configuration to a raised position. Preferably the horizontal component of the attachment has a channel adapted to retain the sheet and float when in the stowed configuration and the channel has an overflow pipe and a detachable cover. Additional vertical struts can be arranged within the opening 6 for added support. |
