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 linkage brick assembly, comprising: a least one first linkage brick, at least one second linkage brick and at least one third linkage brick, each linkage brick comprising a top face, a bottom face and four side faces between the top face and the bottom face. Each of the side faces of the first linkage brick forms a traverse engaging groove extending laterally. Each of two opposite side faces of the four side faces of the second linkage brick forms a traverse engaging protrusion extending laterally and each of the other two opposite side faces forms a vertical engaging portion extending vertically. Each of the side faces of the third linkage brick forms a vertical engaging groove extending vertically. Each of the traverse engaging grooves of the first linkage brick is used to engage with each of the traverse engaging protrusions of the second linkage brick through lateral sliding. Each of the vertical engaging grooves of the third linkage brick is used to engage with each of the vertical engaging protrusions of the second linkage brick through downward sliding. Assembly of the linkage brick assembly of a large area can be achieved by way of the interlocking of only three types of linkage bricks.

A stencil device for forming configurations in deformable material includes a first member having ridge portions integrally joined to channel portions that promote the insertion of the ridge portions of the first member into deformable material; and a second member having ridge portions integrally joined to protrusion portions that promote the insertion of the ridge portions of the second member into deformable material; whereby, the first and second members ultimately form a design pattern across a preselected surface of deformable material by alternating the insertion and removal of said first and second members across the preselected surface of the deformable material.

The invention taught is a method and apparatus to mix a special polymer, hot water or other hot water material containing additives and a special mixture of dry growing substances mixed in a particular way so that they may be applied to structures such as to ceilings, walls, and any grade of vertical slants, commercial roofs, courtyards, indoor and outdoor applications. The purpose is to coat any surface and grow any plant for any reason be it erosion control, beautification of an area. The invention would help in reforestation after fires and such. This invention has a wide range of applications and so it is impossible to limit it to just one of these applications. Green parking lots and green areas that before could not be made green is just one area for the invention

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

A one piece water permeable paver for forming a surface suitable for traffic having outer flex joint connection cells connected to connectors, outer three connection cells connected to one of the outer flex joint connection cells, outer two connection cells connected to two outer three connection cells, a plurality of inner single flex joint connection cells connected to one of the connectors, and an inner dual flex joint connection cell engaging two connectors, inner four connection cells connected to a pair of outer three connection cells and a pair of inner single flex joint connection cells. Fastening slots are formed partially through outer surfaces of cells that form two sides of the paver. Locking tabs extend from outer surfaces of cells forming two sides of the paver opposite the sides with the locking tabs, enabling a first paver to securely interlock to an adjacent paver.

A kit including a plurality of interior paving blocks and a plurality of edge paving blocks.

A paving block having interior drainage.
