Various embodiments for a panel that may be combined with other similar panels to form a padding layer of an athletic field, or other surface, are disclosed. The panel for use in a padding layer of a panel system includes at least one water accumulation region positioned at or near a perimeter of the panel. The at least one water accumulation region is defined by a pyramidal surface that slopes downwards from a center of the panel to distal edges of the panel such that the center has a height relative to a ground surface greater than the distal edges of the panel, a plurality of projections projecting from the pyramidal surface, and a ridge projecting from the pyramidal surface, the ridge extending along a perimeter of the panel, wherein the ridge has a projection height sufficient to retain water at the perimeter of the panel.

A module mat system with first layer that is joined to a second layer by fusion welding, hot welding, hand welding, seam welding, heat pressing, or other methods know to those having skill in the art. Each layer has a central core with a first cellular structure formed from ribs extending from the interior surface. The cross section of the ribs in the central core of the first layer matches the cross section of the ribs in the central core of the second layer such that when fusion welded together the ribs of the central core of the first layer weld to the ribs of the central core of the second layer.

There is disclosed a foundation system made up of panels for supporting a load bearing surface on underlying ground in use. Each foundation panel has a panel body having a peripheral edge, first and second opposing major surfaces spaced by a depth dimension of the panel body, and a plurality of internal walls upstanding in the depth dimension so as to define a plurality of cells within the panel. Each cell of the panel is open at one of the first and second major surface and closed at the other of the first and second major surfaces. Connection formations are provided at the peripheral edge of the panel body, where the connection formations comprise a neck portion and a head portion. The head portion is configured to engage with a corresponding connection formation of one or more adjacent panel in use to resist separation of the foundation panel from an adjacent panel in a direction within a plane of the first or second major surface. A support surface may be assembled using multiple foundation panels, each connected to an adjacent panel.

A tile, which may be a component of a modular flooring system, includes a plurality of cells on its underside, adjacent cells being interconnected to form two sets of channels parallel to the upper surface and open to the underside of the tile. The tile may have recesses in its upper surface, into which inserts can be pressed to form a decorative pattern. The channels may be used as ducting for cables under the floor surface. The cables can be held in place by clips that bridge between a pair of the cells. The cables may include a lighting cable, which can be arranged to transmit light to the upper surface of the tile through inserts that are translucent.

A polymeric structure includes a first polymeric component and a second polymeric component, the first polymeric component including a first mating surface and an opposing first free surface and the second polymeric component including a second mating surface and an opposing second free surface. The first polymeric component and the second polymeric component are positioned with the first mating surface facing the second mating surface. A charge of molten polymer is disposed between the first mating surface and the second mating surface. A compressive force is applied to the first free surface of the first polymeric component and to the second free surface of the second polymeric component in order to secure the first polymeric component to the second polymeric component in order to form the polymeric structure. The polymeric structure may be a construction mat.

The subject of the invention is a support panel with cellular core structure and the manufacturing process for the support panel with cellular core structure which solve the technical problems of: facilitating the manufacture of the product, ensuring compactness of individual panels and manufacturing support panels with cellular structure (1) in a single step. The support plate with cellular structure (1) comprises at least the upper solid surface (2), the lower solid surface (3) and the cellular structure (4), whereby all of these components are made of any thermoplastic material; however, all of the components are made of the same material. The cellular structure (4) is constructed with energy directors (5) to prevent spacing between the cellular structure (4), the upper solid surface (2) and the lower solid surface (3). The pre-formed cellular core (4) is placed on the levelled thermoplastic material used to form the lower solid surface, after which the material is applied over the cellular core (4) up to the depth required to form the lateral surfaces and the upper solid surface (2). After heating and pressing the material, the support panel with cellular structure (1) is cooled under pressure, and then it is removed from the press mould.
