<p>A temporary modular flood barrier is formed from a plurality of modules, each module comprising a spine wall 2 upstanding from a base plate 4. The wall has a formation 8 at each end co-operable directly or through an intermediÂate coupling member with a formation on the next adjacent module to connect the walls together. The spine wall has at least one aperture 10 in the face, the at least one aperture surrounded on each face of the wall with a continuous sealing formation 12. A pair of flexible anchor bags 14, 16 overlay the base plate 4 on each side of the wall 2. The bags are adapted to be filled with water and closed, to provide flexible ballast to hold the base plate on the ground. A flexible rear ballast bag 34 is placed over the anchor bag against the rear face of the spine wall, the bag having a front face proÂvided with an opening surrounded by a continuous sealing formation co-operable with the sealing formation on the rear face of the wall. The rear ballast bag seals to the rear face of the wall, so that flood water passing through the front ballast bag 18 and through the wall enters and fills the rear ballast bag.</p> |
