A flood protection barrier and method of sealing an opening against flood water
A flood protection barrier comprising first (22, Fig. 2), second (32, Fig. 2) and third (50, Fi.g 6) gasket portions; a biasing mechanism 18; and a barrier member between the gaskets. The gaskets engage first, second and third interior parts of an opening respectively; the second part opposite the first and the third located between them. The biasing mechanism biases the first and second gaskets away from each other to seal against the interior parts. The gaskets comprising a water-swellable elastomer material comprising particles of water absorbent material embedded in an elastomer matrix. The water-swellable elastomer material may further comprise water-soluble material embedded in the matrix. There may be a second biasing means 20 for sealing the third gasket against the third interior part. The barrier member may comprise a flat panel 2 and the second and third gaskets may be retractable and extendable in the plane of the panel.
