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.

Embodiments of the present invention relate to an artificial paver comprising 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 attachment device for attachment to a pathway comprising a body having: a top surface for receiving foot traffic thereon; at least one point of flexure; and at least one arm extending from the point of flexure with the arm moveable about the point of flexure, the at least one arm configured to engage the pathway or a structural member of the pathway, wherein when engaged, the at least one arm secures the device to the pathway, wherein engagement of the at least one arm results in the device being compressively secured to the pathway in between two component members of the pathway.

A border member for establishing a border around a synthetic turf field comprises: an elongated body molded from a flexible material; at least one notch formed in an upper surface of the elongated body and extending along a length of the elongated body; and a rigid spine embedded within the elongated body and extending along the length of the elongated body. The border member is positioned adjacent to the synthetic turf field such that a portion of synthetic turf of the synthetic turf field rests on the notch.

A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface.
