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. Due to the above structures, fast assembly of the linkage brick assembly of a large area can be achieved by means of the interlocking of only three types of linkage bricks.

A grass paver makes possible reduction of the product volume of grass paver panels during stoking thereof, thus, improving both transportation and storage characteristics of such assemblies and cutting down the transportation expenses due to introduction of apertures on the cell edges that makes it possible to stack the panels bottom to top and top to bottom. Additionally, apertures in the cell edges also ensure good growth of roots in horizontal direction in intercellular space due to the apertures mentioned above.

There is provided a void forming module (100), the module including a support surface (110) including a first generally planar upper region (112), a second generally planar lower region (114), and a third generally convex region (116) joining the first region and the second region. At least one of the first region, the second region, and/or the third region includes at least one aperture (120,122) for the passage of fluid through the void forming module. There is also provided a structure (200) including the void forming module, a method of preparing a structure, and the use of the void forming module.

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.

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.

A grass protection mat that includes a plurality of bodies formed with grass passing spaces and one or more contraction-expansion compensatory connectors connecting a plurality of bodies. The grass protection mat and compensating compensates for contraction or expansion of the mat units.

A grass protection mat comprises a body where grass passing spaces are continuously arranged and an outer frame comprising four frames formed in four directions to finish an outer edge of the body, wherein the grass protection mat further comprises at least one hook fastener which horizontally protrudes from a first lateral frame of the outer frame toward a second lateral frame of an outer frame of a neighboring grass protection mat, and wherein the at least one hook fastener is fastened to at least one fastening hole provided in the outer frame of the second grass protection mat adjacent to the first lateral frame and corresponding to the hook fastener of the grass protection mat.

A water generation system for deserts is provided as a water generation system designed for desert climate areas and constructed in a surface pavement and generally includes a sand layer, which includes a water tank embedded therein and is covered with a moisture locking cloth on which a grading layer is laid. A water resisting cloth is arranged in the grading layer. Hollow water penetration tubes are arranged above the grading layer and have bottoms extending through the water resisting cloth and inserted into the grading layer with pouring and grouting of grout cement thereon to form a water pervious layer. As such, rainwater can be quickly conducted into the sand layer for storage for subsequent uses and air can be conducted into the grading layer to subject to condensation for forming condensed water on an undersurface of the water resisting cloth to achieve a purpose of automatic water generation.

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.

Disclosed is a universal mold having removable arm members and socket members that can be configured to fabricate the border blocks, the corner blocks and the interior blocks.
