A flood defence1 in the form of fencing substantially constructed from timber and concrete in which a waterproof membrane 15 is sandwiched between two wooden panels (5 & 6 figure 6), the membrane extending below the lower edges of the panels in use and embedded in a concrete base (3 figure 1a). The panels may be constructed from horizontal layers of tongue and groove boards 10 placed back to back, wherein the membrane may be a damp course membrane. The panels (5 & 6 figure 6) may be staggered vertically relative to each other so that the lower edge of the panel nearest the flood risk is higher than the lowest edge of the panel furthest from the flood risk. The panels may be supported in an upright position by posts (7 & 8 figure 6). A later embodiment relates to a method for constructing said flood defence. The flood defence provides effective flood defence qualities whilst having aesthetic appeal. |
