ABSTRACT:
A system for the construction of cribbing and retaining walls includes a series of precast reinforced concrete blocks, the blocks each having a longitudinal ridge along the bottom surface and longitudinal and lateral channels on the upper surface. A number of courses of the blocks may be built up with the longitudinal channels of an underlying course mating with the ridges of the next overlying course to interlock for greater strength. Additionally, positive horizontally and vertically interlocking corners may be formed by mating the underlying lateral channel of one block with the overlying longitudinal ridge. The blocks may be formed using only two molds having two different lengths with all other dimensions the same, so that one longer length block plus the width of another block are equal to the combined length of two shorter blocks. In this way, the various blocks may be overlapped to interlock and form a variety of various structures for retaining and cribbing walls.
