Abstract A method and means is provided for protecting slope revetments of banks and of harbor basins and waterways against crumbling under the water line. The method includes the step of supporting the foot of the revetment with an oblong body which extends in the longitudinal direction of the slope and which is suspended from a carrier. This carrier rests at least in part on the slope and is covered by the revetment.
