Abstract
An interconnected block system including a plurality of staggered rows of block members formed of concrete or the like secured to the upper surface only of an underlying, interconnecting, grid-like, matrix sheet. In one embodiment, a plurality of connector elements are connected to the matrix material preferably by bodkin connections to form one or a multiplicity of openings or apertures above the upper surface of the matrix sheet for reception of the block-forming material. The block members are cast on top of the matrix sheet material to capture the connector elements which provides a mechanical interlock between the block member and the matrix. The matrix sheet material preferably includes a layer of geotextile bonded on an opposite side from the block members. An alternate embodiment provides a strip or mat to underly the matrix sheet with a plurality of projections upstanding therefrom and passing through the matrix sheet. Free end portions of the projections are configured to retain block-forming material cast to surround the projections. Multiple layers of interconnected blocks may be made without waiting for the concrete to set by using preformed mold elements which are lef…
