A plastic patio paver block comprises a top panel, a sidewall depending downwardly from a periphery of the top panel, a plurality of internal support members that depend downwardly from an inner face of the top panel and that are spaced inwardly from the sidewall, a plurality of drainage openings provided in the top panel, and a granular UV resistant material embedded into an upwardly facing plastic face of the top panel, wherein a portion of the granular UV resistant material is partially embedded in the upwardly facing plastic face.

A method for treating a plastic block comprising using heat to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face. A method for treating a plastic block comprising using compressive force to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face.

A mat comprising a first side and a second side opposite the first side is disclosed. The mat has a body with a thickness defined between the first side and the second side and a width defined between a first edge and a second edge. A plurality of fortifying members can be positioned between the first side and the second side extend within the body substantially vertically with respect to the width. A lip can extend from the body of the mat and have a first rib having a first rib thickness. A first channel portion can have a first channel thickness whereby the first rib thickness is greater than the first channel thickness.

A modular tile is disclosed configured to interlock with multiple tiles to form a modular floor covering over a floor. The tile includes improved grip and bounce characteristics. The tile may include an upper contact surface having rib with top edges that are sharp. Protrusions may extend from the upper contact surface to provide grip and increase ball bounce performance. The tile may be made of a composite of rigid plastic and rubber to improper bounce characteristics, including by increasing the degree to which the tile conforms with a subfloor.

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 flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.
