Abstract:
A block for use in controlling soil erosion comprisinga) a light-weight, generally L-shaped, hollow block of rigid, durable plastic, said hollow block including a pair of spaced vertical extending walls defining a first arm of an L-shape, and a top and bottom defining a second arm of the L-shape and two side walls creating an enclosed hollow space;b) first means adjacent a first end of said block to enable said block to be connected to an adjacent block;c) second means adjacent a second end of said block to engage said first means of an adjacent block to enable said connected blocks to form an interlocked retaining wall;whereby said light-weight, generally L-shaped, hollow blocks may be easily positioned to form said interlocked retaining wall and then fill is added to each said hollow block within said enclosed hollow space to provide resistance to forces associated with soil erosion control.
