Abstract
Interlocking blocks for the stabilization of stream and river banks and ct lines, road bed embankments, and boat ramps, are made of concrete, and have a high proportion of open area. Interlocking connections between adjacent blocks are made by radial projecting members and recesses on the periphery of each block, the projecting members of one block fitting into the recesses on adjacent blocks. Projections and recesses are alternately provided at regular angular intervals such that blocks can be assembled in either square or an equilateral triangular patterns. A layer of filter cloth material is laid on the sloping surface and upon which the blocks are then placed; this filter cloth slows down the leaching of water through the open areas between the interlocking blocks and prevents the washing away of sand and silt by stream or river water or rainwater runoff.
