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 porous pavement construction formed from environmental porous pavement materials is formed with a number of aqueduct channels located underneath the pavement surface, so that water can percolate downward into the pavement and enter the channels. Methods of forming this pavement structure are also discussed.
Abstract:
A paving machine forms aqueduct channels using a screed assembly having elongated forming arms, and deposits pavement material onto these arms. As the machine advances, channels are formed in the pavement layer. This results in a porous pavement material having a number of aqueduct channels formed underneath the pavement surface, so that water can percolate downward into the pavement and enter the channels.
Abstract:
A preformed surfacing for a pavement is in the form of a sheet of flexible material containing cavities open to its upper surface and interconnected by ducts beneath the surface so that when laid down on a prepared subsurface having a drainage slope, water falling on the surfacing can drain away through the cavities and ducts. The sheet can be fixed to the subsurface by anchors bonded into cavities in the sheet.
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.
Abstract:
Es werden eine Drainageverbundplatte und ein Aufbau mit Natursteinen, Betonsteinen oder Fliesen vorgeschlagen. Ein einfaches Verlegen bei guter Abdichtung und Entwässerung wird dadurch ermöglicht, daß die Drainageverbundplatte mit ober- und unterseitigen Nuten sowie diese Nuten verbindenden Durchbrüchen und/oder einer vorzugsweise aus Bitumen bestehenden Dichtungsschicht versehen ist, wobei die Betonsteine, Natursteine oder Fliesen unmittelbar auf die Drainageverbundplatten aufgeklebt oder nur aufgelegt werden.
Abstract:
Die Erfindung betrifft ein Bodenbelagselement (10), umfassend eine starre Obermateriallage (12) und eine zur Auflage des Bodenbelagselements (10) auf einem Untergrund vorgesehene Untermateriallage aus elastisch verformbarem Material. Das elastisch verformbare Material umfasst Gummigranulat und/oder an wenigstens einem Umfangsrandbereich (18,20,22,24) ist ein Abstandshalter (42) vorgesehen, der in der Untermateriallage getragen ist.
Abstract:
The invention relates to a system of shaped blocks, comprising full blocks with an essentially rectangular base and half-blocks, which are essentially formed by halving the full block in the transversal central plane, for laying in the longitudinal bond. Each section (2a, 2b, 3a, 3b) of the longitudinal sides of a full block (1a), which are separated by a transversal central plane (7), has at least two studs (12, 13; 14, 15; 43, 44; 45, 46), the stud (12; 15; 43; 46) that is closer to one transversal side (4, 5) of the shaped block (1) forming an interlocking pair (48) with a stud (13; 14; 44; 45) of a corresponding block that is further from a transversal side (4, 5), said pair being positioned at least a stud-width away from an interlocking pair (49) formed by the stud (13; 14; 44; 45) that is further away from the transversal side (4, 5) and the stud (12; 15; 43; 46) of the corresponding block that is closer to the transversal side.
