An artificial paver comprises a physical member adapted to have a structure shape of a paver and located on the top surface of a paving area. The physical member may be made of a two-component polyurethane material, and the two-component material may be formulated to characterize the artificial paver to be softer than a stone or concrete paving object and to exhibit higher shock absorbing properties than the stone or concrete paving object. A method for manufacturing the artificial paver is also contemplated. The method may comprise pouring the two-component polyurethane material into molds, allowing the two-component polyurethane material in the molds to cure, demolding the cured two-component polyurethane material, and applying an UV stable polyurethane and slip-resistant coating to a surface of the demolded two-component polyurethane material.

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.

System for supporting an upright member from a support surface includes an elongated carrier releasably engageable with the support surface, a base adapted to extend around at least part of the lower end of the carrier and abut the support surface and at least one anchor associated with the carrier and configured to grip the upright member when the upright member is inserted into a bore of the carrier.

A modular tile for a walkway system interlocks with another tile to constrain movement of the interlocked tiles in all three-dimensions. The tile includes a male projection which may be tapered to provide lateral wings that are received in corresponding pockets of a female receiver of the other tile. The wings may include vertically-facing male stop surfaces that are engageable with vertically-facing female stop surfaces within the pockets. The male projection may further include a forwardly protruding ridge that is received in a corresponding groove of the female receiver of the other tile. The engagement of the stop surfaces of the wings and pockets, and the engagement of the ridge in the groove is such that the tiles are vertically interlocked with each other. The tiles may be configured to enable a pivotable interlocking connection while one tile remains on the ground.

A ground cover mat includes a slab that encases a core assembly. The slab is made of a rubber material and defines a lower major surface and an upper major surface of the ground cover mat. The core assembly comprises horizontally extending boards, which may be made of wood, disposed in horizontally spaced apart, side-by-side relation with each other. The core assembly further comprises a rebar mesh, which may be made of steel, that is disposed on top of and in contact with the boards.

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the upper surface and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The mats also include first, second, third and fourth sides forming a perimeter of the mat, wherein the first and second sides include upper structures having a sloped lower surface and the third and fourth sides include lower structures having sloped upper surfaces. The sloped surfaces are configured to allow for overlapping with sloped surfaces other like mats for interlocking therewith while forming a generally flat continuous top and bottom surface of the overlapped mats. The mats may be interlocked by a fastening member which fits in aligned openings of the adjacent mats for connection therewith.

The panel mats also have first, second, third and fourth sides that are configured with tabular extensions or openings, slots or recesses configured and dimensioned to be able to receive the tabular extensions. At least some of the tabs and slots are configured to facilitate snap-locking. Thus, a plurality of similarly configured panel mats can be connected by interlocking of the tabs of one mat into the openings, slots or recesses of one or more adjacent similarly configured mats.
