A flood barrier arrangement and a method of preventing flooding of a structure

摘要

The barrier includes an anchoring member 110, impermeable to water, for positioning around the edge of a building, and a water impermeable skirt 350/330, attachable to the anchoring member at one end 352 and attachable to an external wall 121 of a building, around which it is used, at the other end thereof 332 to cover a lower portion of the building wall and prevent the ingress of flood water. The skirt may be a single flexible sheet or membrane, or may have a first portion 350 removable attached to a second portion 330 via a zip 360. The skirt may have a deployed configuration in which it is secured to the building wall, extending from the anchoring portion, and a collapsed configuration in which it is rolled or folded in a dedicated container, or the second portion 330 may be removed and stored elsewhere. The anchoring portion may be a plurality of buried interlocking blocks 110 extending around the perimeter of the building with a locking recess for housing the bottom of the skirt and an elastic fixing mechanism 140 such as a string or rope also extending around the perimeter of the building.
