The disclosure features structural tiles and methods for forming such tiles, the tiles including a tile body featuring one or more polystyrene materials, and a coating featuring an epoxy resin and an aggregate material, disposed on at least one surface of the tile body, where the structural tile has a dry coefficient of kinetic friction of at least 0.75 and a wet coefficient of kinetic friction of at least 0.70, and where the dry coefficient of kinetic friction is larger than the wet coefficient of kinetic friction by 0.05 or less.

A PV panel assembly includes a PV panel and a frame. The PV panel includes one or more PV cells and is operable to provide electrical power at a panel output terminal in response to operating light incident on a panel upper surface. The frame extends along the panel peripheral edge and defines a frame inside surface which, together with a lower panel surface, defines a base volume. A molded base material is located in the base volume. A light-transmissive cover material extends over the panel first surface and over at least a portion of a frame outside surface which faces away from the base volume. The PV panel assembly may be incorporated in a landscape installation and connected with other such assemblies in the installation to provide a ground mounted PV panel array which also functions as a hardscape such as a walkway or patio.

Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation.

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.

An inventory of industrial mats having different core or internal constructions that are not visible because of the inclusion of side, end, upper and lower components which hide the core or internal construction from view, wherein each mat has an electronic device that indicates what is present in the hidden core or internal construction of the mat, with the electronic device including a processor, storage, and wireless communications circuitry that is configured to transmit identification, location, usage or physical property information of the mats over a wireless telecommunications network. Also, a method for providing an identification of mat properties or usage for an inventory of mats by viewing the information stored on the electronic device or by retrieving over a wireless telecommunications network identification, location, usage or physical property information of the mats from the storage of the electronic device.

A landscape paver includes a PV panel and a frame. The PV panel includes one or more PV cells and is operable to provide electrical power at a panel output terminal in response to operating light incident on a panel upper surface. The frame extends along the panel peripheral edge and defines a frame inside surface which, together with a lower panel surface, defines a base volume. A molded base material is located in the base volume. A light-transmissive paver cover material extends over the panel first surface and over at least a portion of a frame outside surface which faces away from the base volume. The landscape paver may be incorporated in a landscape installation and connected with other such pavers in the installation to provide a ground mounted PV panel array which also functions as a hardscape such as a walkway or patio.
