Foam insulation boards having an improved shiplap edge for interfacing with one another are disclosed.

An interlocking paver system including a polygon paver and a spacer paver is provided. The polygon paver may have a top level having a top level polygon paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level polygon paver perimeter contained within the top level polygon paver perimeter. The spacer paver may have a top level having a top level spacer paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level spacer paver perimeter extending beyond an entirety of the top level spacer paver perimeter. The spacer paver may be configured to selectively interlock with the polygon paver. The top level spacer paver perimeter, top level polygon paver perimeter, and bottom level spacer paver perimeter are different from one another.

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.

A modular system for streets formed of a top module, a bottom module, an internal cavity formed within the bottom module, cables positioned within said bottom module, a computing device, sensors operatively associated with said computing device, and communications hardware configured to communicate information from said sensors to a second computing device positioned exterior to said modular system.

A support product configured to receive poured concrete, the support product comprising a latticework of walls and a plurality of edges, wherein the walls extend between a lower surface and an upper surface and define a plurality of cells, wherein at least one edge comprises a catch and a partial keyway, wherein the catch is configured to connect with a catch of an adjacent support product to restrain relative movement of connected support products, and wherein the partial keyway is configured to be located adjacent to a partial keyway of a connected support product, so that adjacent partial keyways define a complete keyway between connected support products.

1. A panel system is provided that includes: a first and second panel each having a top side providing a road surface and a bottom side opposite the top side, where the bottom side contacts a ground surface, and a plurality of lateral sides. At least one of the plurality of the lateral sides of the first and second panels include a feature that interlock adjacent lateral sides of the first and second panels against vertical movement relative to each other.

An interlocking tile includes a top surface, a bottom surface, and marginal faces disposed along a perimeter of the top surface. The tile also includes at least one male coupler disposed on a first marginal face and at least one female coupler extending from the bottom surface and disposed on a second marginal face. The at least one female coupler includes an arm, the arm comprising a first notch for engaging with a corresponding male coupler of an adjacent tile at a first position, and a second notch for engaging with the corresponding male coupler of the adjacent tile at a second position.

Generally L-shaped, square, rectangular, triangular, hexagonal, parallelogram and other-shaped paving stones with inter-fitting vertical spacers forming serpentine side contact surfaces that provide enhanced stone-to-stone interlocking in both water-permeable and water-impermeable paving installations.

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.
