  • Patent number: 7048469
    Abstract: A flexible, molded, polymeric grid is embedded in a predominantly concrete mat comprising a concrete slab having relatively thicker portions defining blocks connected by relatively thinner portions, along which the concrete slab is breakable. The flexible grid has two longitudinal edges, two transverse edges, longitudinally extending members, and transversely extending members, where the longitudinally and transversely extending members connect the blocks to one another when the concrete slab is broken along the relatively thinner portions. The longitudinally and transversely extending members meet at nodes, which are spaced uniformly from one another, both longitudinally and transversely, except that, along the longitudinal and transverse edges, each node is spaced more distantly from the nodes nearest to the node. When the longitudinal and transverse members are disposed in an imaginary plane and the flexible grid is not stressed, fingers, which are unitary with the grid, extend from the imaginary plane.

  • Patent number: 6942421
    Abstract: In the manufacture of an articulated, predominantly concrete mat, which comprises concrete blocks and a flexible geogrid embedded in such blocks and in which the flexible geogrid defines flexible members connecting such blocks to one another, an intermediate article being a concrete slab is cast, in which a flexible geogrid is embedded. The slab has relatively thinner portions, along which the slab is breakable to form such blocks, and relatively thicker portions, which become such blocks when the slab is broken along the relatively thinner portions. The relatively thicker portions are arranged in parallel rows and are staggered in adjacent rows, before the slab is broken therealong, and the relatively thicker portions in alternate rows are aligned in parallel columns, before the slab is broken therealong.

  • Patent number: 6692195
    Abstract: For abating noise along a highway, along a railway, or along another noise-generating way, a wall having an anterior face and a posterior face comprises, across each face, concrete modules stacked in an upper tier, at least one intermediate tier, and a lower tier. Each module is plantable and has a batten. Across each face, the modules are spaced laterally from one another in courses, one course in each tier, so that modules of each course straddle modules of the next course above or below said course. In each of alternate ones of the tiers, a geogrid strip is deployed around the battens of the modules along the anterior face and around the battens of the modules along the posterior face, in a zig-zag pattern, so as to tie the modules along the anterior face to the modules along the posterior face.
