A pile wrapper is in the form of a flexible sheet (1,2) which, when encircling a pile, has two contiguous edges. These have abutments (8) which are urged together by a power tool (13) and fastened, conveniently by nuts (19) and bolts (18). The hoop tension induced in the wrapper resists wave suction forces. The wrapper can have an inner layer (2) containing a water resistant sealant which is forced into intimate contact with the pile as the tension is applied. The wrapper may also be given anti-fouling and cathodic protection properties.
