    (54) Underwater wall construction


    (57) A wall is constructed underwater by successively filling buoyant shells which define courses of the wall. The shells may be integral, concertina-folds of a polymer plastics bag (2) which is initially secured to the bed on which the wall is to rest, or polymer concrete boxes (30) which are interconnected laterally and which float on the surface before filling. The shells are preferably filled with a hydraulic fill material which is pumped into it.
