PCT No. PCT/DK81/00057 Sec. 371 Date Jan. 18, 1982 Sec. 102(e) Date Jan. 18, 1982 PCT Filed May 27, 1981 PCT Pub. No. WO81/03512 PCT Pub. Date Dec. 10, 1981.A revetment protecting coasts and structures thereon against erosion from waves and flowing water. The revetment comprises a plurality of heavy and thick plate bodies (1a-1d) located side by side and directly on the inclined surfaces of the coast. Each plate body comprises at a first pair of opposite ends hinge pins (1', 1'') for a flexible securing of the plate body (1d) to the adjacent plate body (1c). Furthermore, the plate body comprises a plurality of substantially vertical water penetration holes (4', 4'') as well as two hinge openings (2', 2'') located at a second pair of opposite ends of said body. The hinge openings are shaped in such a manner that they beyond penetration of water also may receive pins (1', 1'') of the adjacent plate bodies (1a). In this manner a revetment is obtained which is water-permeable, coherent, appropriately heavy and flexible, and which furthermore in an easy manner may be mounted by unskilled persons.
