Abstract:
A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece molding that supports a compressive load placed thereon, the molding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight and interlinking members that act to share the load among the various cells. The design is cheaper to produce and allows easy access of the void space for filling and laying utility lines.
Abstract:
Systems and methods for a porous pavement system are described. The porous pavement system includes paver blocks designed to facilitate water seepage between the paver blocks and to permit water storage within the blocks. The paver blocks may be cabled together to create paving units that facilitate installation and maintenance of the pavement system. The porous pavement system provides improved management of stormwater, reducing runoff and facilitating infiltration of stormwater into the subgrade below the paving system.

Abstract:
An essentially quadrate paving stone having a corresponding base block (21) is provided on all four side surfaces (25, 26) with flange-like, upright spacers (22) which are spaced apart from each other at intervals corresponding approximately to the width of the spacers, making it possible for them to make an interlocking connection with adjacent shaped paving stones of the same type. Furthermore, the bottom side (24) of the paving stone features a number of transverse, gutter-like depressions resulting in the formation of ribs between these depressions. This creates an additional dentification, or anchoring, in the bed surface of the installed paving stones.
Abstract:
A flexible shock absorbing component providing cushioning for surfaces, especially wall and floor surfaces, is described. The shock absorbing component includes two sheets of thermoplastic, each sheet with inwardly facing, opposing, resiliently compressible indentations extending into a cavity between the two sheets. The shock absorbing component also includes a layer of particulate matter applied to and adhered to the outer surface of one of the sheets, to provide wear and weather resistance. A moderator may also be attached to the outer surface of the sheet.
Abstract:
A paving stone (1) has a linkage securing against displacement. This is achieved by overengaging interlocking elements (6) and underengaging interlocking elements (5) being respectively provided on each side (3, 4) of the paving stone (1).
Abstract:
A cover device for gratings, having a planar support (1) and a plurality of holding elements (20) which protrude at a bottom side (7) of the support (1), wherein a plurality of elevations (10) and recesses (11) are provided on an upper side (6) of the support (1).
