A flexible blanket for protection or stabilisation of underwater structures and pipe lines, sea and river beds, etc., the blankets comprising a plurality of segments (1) arranged in one or more layers (7) each one segment in height. The segments of the or each layer are disposed substantially contiguously at least at a median zone of their height dimension, each segment tapering substantially regularly from a maximum cross-section at the median zone to a minimum cross-section at one or both ends thereof. The segments are so joined to one another in the region of their respective median zones that they are held substantially contiguously but are free to pivot relatively to one another insofar as is permitted by the taper. |
