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 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).
Abstract:
A support layer for supporting an artificial turf assembly. The support layer being formed of a polymeric foam, preferably having a density of between 20 and 70 grams per liter, such as a polyolefin foam; and having an upper side and a lower side, wherein in use the support layer has been placed with the lower side thereof on a base surface and supports, on the upper side thereof, the artificial turf assembly, the support layer including a plurality of through drainage holes extending from the upper side to the lower side for allowing liquid such as rain water to flow via the plurality of drainage holes from the upper side to the lower side, and also including a plurality of channels at the lower side for allowing liquid such as rain water to flow through the channels along the lower side, wherein each of said plurality of drainage holes debouches into one of the plurality of channels. The support layer is further included in an artificial turf system, that includes an artificial turf assembly with the support layer supported on a base surface such as a layer of sand, wherein the support layer forms, at the upper sides thereof, a closed support surface supporting the artificial turf assembly.
Abstract:
Disclosed is a multifunctional synthetic resin block for roads. The synthetic resin block includes a water permeable sheet configured as a synthetic resin block having a flat sheet shape so as to be laid on a ground, a block frame configured as a synthetic resin body taking a form of a rectangular frame, which is divided into multiple rectangular areas each having open top and bottom sides, so as to be installed on the upper surface of the water permeable sheet, the rectangular areas being filled with filler stones, and multiple corrugated plates each configured as a synthetic resin having a rectangular plate shape and arranged so that corrugations thereof are oriented perpendicular to each other so as to cover the rectangular areas of the block frame. The synthetic resin block provides almost all functions, such as a rainwater retention function, water permeation function, and anti-slippage function, at low cost.
Abstract:
A method for installing a paver system includes positioning a first grid substrate adjacent to a second grid substrate. The first grid substrate and the second grid substrate are flexibly bridged with a first paver piece. A first portion of the first paver piece is movably coupled with the first grid substrate at a first joint, and a second portion of the first paver piece is movably coupled with the second grid substrate at a second joint, the first and second grid substrates and the first paver piece forming an articulated paver linkage. A second paver piece is coupled with the second grid substrate. A third paver piece is coupled with the first grid substrate. The articulated paver linkage is fit within the specified area by movement of at least one of the first, second and third paver pieces and the first and second grid substrates. The movement is transmitted along the articulated paver linkage to maintain a specified alignment and spacing of the first, second and third paver pieces.
Abstract:
A permeable surface covering unit comprises a top surface and at least two pairs of irregularly shaped mating sides, one or more passageways extending downwardly from the top surface, and at least one under channel connected to the passageways for retaining liquid, such as storm water. The sides of the unit preferably define an irregular rotational tessellation element. The passageways may comprise gaps or side cavities between units and/or core cavities or other passageways within the unit. Optional undercuts may be provided in the core cavities. Pervious material plugs are cast into the cavities extending into the channel or undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces. A permeable surface embodiment comprises a combination of pervious and impervious units, wherein the ratio of permeable to impermeable units and resulting surface absorption rate may be adjusted.
