  • Patent number: 5967701
    Abstract: An apparatus and a method for stabilizing sloped embankments is disclosed which utilizes interlocking barrier elements to form a step-like, cascading barrier to erosion and to provide an inexpensive, easy-to-install and aesthetically attractive landscaping wall, planter or landscaping island. The scallop or channel-like shape of the barrier elements creates filler spaces which may be filled with concrete, soil or other filler materials and in which vegetation may be planted. A row of barrier elements within the system may be locked in place by slip restraint devices which function to prevent vertical slippage of the rows. Adjacent barrier elements on the front most row are held together by frontal locking elements. Also disclosed is a barrier element, system and method. The barrier elements have complementary male and female portions. The connectors allow for use of a single barrier element shape to inexpensively create cascading slope armoring barriers, barrier walls and containment structures.
