A modular assembly and method of installing a modular assembly is provided. The modular assembly can include a plurality of base members made of a plastic material, each base member including a top surface and a bottom surface opposite of the top surface, the bottom surface defining channels. A plurality of support members can be provided, each of the plurality of support members may extend across the plurality of base members and disposed within the channels of the plurality of base members. A mounting bracket can be configured to mount each of the plurality of support members to a metal plate of a lower support structure, the metal plate being received by a clamp of the mounting bracket. Each of the plurality of base members can adjoin one another to form a horizontal platform for traffic.

A ground cover mat is provided for vehicles and equipment to cross over pipes, whether laid below or above ground. The mat includes two footing members spaced at a distance from each other. Each of the footing members define therein multiple peg holes, and each of the peg holes spaced at different distances from an outer edge of a given footing member. The mat also includes one or more span members. Each of the span members are positioned above and removably attached to the two footing members. Each of the one or more span members comprise at least two pegs that protrude downwards, wherein one of the pegs removably fit into a given peg hole defined in one of the two footing members and another one of the pegs removably fit into a given peg hole defined in another one of the two footing members.

A timber access mat having an electrical grounding feature includes an electrically conductive cover layer that is removably carried over the top of the body of the timber access mat. The electrically conductive cover layer can be formed from one or more sheets of expanded metal such as expanded steel. The layer is joined to a perimeter frame that includes offset connector tabs that allow mats to be positioned side-by-side. The connector tabs are paired with cable guides to protect the cable leads that connect the mats. The perimeter frame and conductive cover layer can be added to traditional timber access mats when electrical grounding is required and then removed and stored when not required.

A safety surface with an engineered shock-absorbing base. The base may include one or more engineered resilient mats. The mats may be fabricated of repurposed tire rubber. The mats may be adjoined edgewise. Adjoined mats may be coupled together. The base may overlay a surface. The base may include upward-facing pockets. Interiors of the pockets may receive loose fill. An upper layer may cover the base. The upper layer may bond to the base. The upper layer may seal the loose fill within the safety surface. The upper layer may include poured-in-place surfacing. The upper layer may be textured. The upper layer may include synthetic turf. Impact upon the upper layer may be attenuated by flexion of the base. Mats may be coupled without hardware fasteners. Exterior surfaces of pockets of one mat may be nested into complementarily contoured features of an adjoining mat.

Disclosed may be an intermediate surface for supporting a small paver, wherein the surface can also be used to exchange heat with the pavers. In one embodiment, the apparatus may be a tray defined by a frame with a lattice for supporting pavers. The tray preferably features a tubing track throughout the lattice to accommodate heat exchange tubing. In operation the tray may be positioned above a pedestal or directly on a subsurface. In embodiment, the tray may be outfitted with insulation and a metal plate so that heat may be exchanged with pedestals via fluid passing through tubing installed throughout the lattice. In a preferred embodiment, the tray features a slot in its corners for receiving a locking disk or locking slider.

A planting system having a plurality of potting trays that can be interconnected in a modular fashion to create a multitude of different configurations. Each potting tray has a plurality of holes operatively connected with a conduit through which plumbing can be incorporated into the planting system to water plants in the potting trays via the plurality of holes. A plurality of pedestals may be used to elevate the planting system. Lateral braces may be used to interconnect the plurality of pedestals.
