Embodiments provide a polymeric walkway for mitigating surface water runoff and a method for constructing the same. A polymeric walkway module is secured to a pre-conditioned ground. The polymeric walkway module includes an upper panel, a lower panel, and a plurality of spacers. The upper panel includes a plurality of perforations. The plurality of spacers is positioned between the upper panel and the lower panel defining a hollow space. Surface water permeates through the plurality of perforations and occupies the hollow space during the surface water runoff.

A tactile tile assembly includes a base having a plate section, a rim projecting up from the plate section, and a plurality of embedment anchors on the base. A tactile tile is adapted to fit into or onto the base. Fasteners extending through the tactile tile attach it to the base. The top of the rim may be substantially co-planar with a top surface projections on the tactile tile. The embedment anchors may be provided in a plane of the plate section and be bent to a position perpendicular to the plate section for embedment into a pavement material. The base has attachment elements for attaching the tile assembly to an adjoining tile assembly. Two or more tile assemblies are attached together to provide a tile assembly combination of a desired size and shape. The tile assembly combination is then installed in the paving material.

A system for assembling a road comprises a plurality of plastic support structures and a plurality of road deck elements. Each of the support structures comprises a base plate and at least one column extending, or for extending, upwardly from the base plate for supporting at least partly one of the road deck elements. Each of the road deck elements is configured such that in an assembled and as road useable condition of the system rainwater predominantly flows away over the road to one or more positions next to the road, and/or to a slit-sized interruption of the road across the road.

A covering element for a floor covering comprising an upper surface having a relief structure, wherein the relief structure comprises excavations having a depth decreasing towards at least one perimetric edge of the covering element.

A deck assembly includes a deck panel having a plate shape extending in a first direction and having a clip insertion groove recessed from each of both side surfaces thereof, a lower support disposed below the deck panel in a second direction that is perpendicular to the first direction, and a quick clip module coupled to one side surface of the lower support to fix the deck panel in a separable manner.

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

A spacer for support elements of a decking or paving support system, has a central region, at least two spacer arms extending laterally from the central region, and a retention portion coupled to the central region, wherein the retention portion has a longest lateral axis extending laterally and wherein the longest lateral axis lies at an angle to each of the at least two spacer arms.

A paving block having interior drainage.

A joist support and joist assembly for use in a decking structure, the joist support and joist being adapted to be fitted together in an assembled position, the joist support including a support body which includes a base wall having a bottom side and a top side, two spaced apart side walls extending from the base wall away from the top side thereof so as to provide a channel having an open top and opposed spaced apart open ends, the channel when in use being configured so as to at least partially receive a joist therein, the joist comprising an elongated body having opposed spaced apart ends, a top wall, a bottom wall spaced from the top wall and spaced apart side walls extending between the top and bottom walls, the bottom wall having an outer side, the joist being at least partially received within the channel when in the assembled position with the outer side of the bottom wall being adjacent the top side of the base wall of the joist support
