A retaining wall block system having multiple sizes and shapes of blocks with
differently
dimensioned, interchangeable front and back faces. The blocks are used to construct
an irregularly textured wall having a weathered, natural appearance. Multiple channels
in the lower face of the block are used to engage pins in pin-receiving apertures
to form an attachment system. A side connection system is particularly useful for
stabilizing free-standing walls. Horizontal reinforcing members are also used in
the channels and vertical reinforcing members are used in cores of adjacent blocks
for reinforcing a wall. Reinforcing geosynthetic materials can also be firmly held
in a wall by means of the pins or by connectors adapted to fit in the block channels.
