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 structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

A paving stone comprises at least one functional region comprising, a primary connecting system comprising at least two upper connecting portions, and a secondary connecting system comprising at least two lower connecting portions; and at least one infiltration region. The at least one functional region and the at least one infiltration region are positioned on a same side of the paving stone. The at least two upper connection portions and at least two lower connecting portions of functional regions of adjacent paying stones are configured to cooperate with each other to form a narrow joint in a region of the primary connecting system and a wide joint in the region of the secondary connecting system. The at least one infiltration region of the adjacent paving stones tbrrn a chamber which is open at a bottom end.

A method of installing a porcelain tile installation for vehicular use is provided. The method can include covering a compacted aggregate surface with a tile bed composition; compacting the tile bed; installing a plurality of porcelain tiles and spacers on the compacted tile bed surface in a predetermined pattern, such that each respective porcelain tile includes a thickness of about 3 cm to about 5 cm; such that one or more spacers includes a base component positioned under adjacent tiles and a vertical component positioned between a sidewall of the adjacent tiles, such that the vertical component provides a joint defined by a spaced distance between the adjacent tiles; adding a polymeric sand composition to each respective joint to obtain a joint-filled porcelain tile surface; compacting the joint-filled porcelain tile surface with a compactor; and activating the polymeric sand composition to obtain the porcelain tile installation for vehicular use.

A cobblestone comprises a bottom side, a top side, and at least one side surface substantially perpendicular to the top side and the bottom side. The at least one side surface defines a plurality of surface features. The plurality of surface features comprise alternating projecting portions and receding portions.

The invention relates to a paving stone (1) and to a paving produced using same. A strip-shaped connection section (4) is provided at least on one lateral face of the paving stone, which vertically projects from same and interacts with strip-shaped connection sections of adjoining stones in the course of producing a paving and establishing a connection. The connection section (4) has a stepped shape with at least three graduated shoulders one over another. This both achieves a joint that expands in the upward direction, and prevents the pointing from loosening or being cast upward when forces act upon the paving, for example when subject to vibrations.

A system and method are provided for designing/creating, preparing, and installing a natural stone tiled surface at a site that provides a perception of randomness to the observer while actually following a predefined pattern that facilitates simple installation by unskilled trades and allows for the advanced preparation of the stone tiles used. Advanced preparation of the stone tiles allows the offloading of at least some cutting, preparation and installation steps normally required onsite, to an offsite location. In this way, significant time and cost savings can be achieved by shifting time and resources to an offsite location, which minimizes disruptions onsite, allows the building of an inventory of standard shapes, all without compromising the aesthetics or quality of the installation. The system relies on the tessellation or tiling of a specific outline of an irregular concave polygon, that itself includes an internal set of irregular convex polygon shapes. The tessellation of an outline that includes such a set of shapes provides an optical effect that makes it difficult for an observer to recognize the repeating nature of the stones within the patterned outline.

The invention relates to a paving composed of a plurality of individual paving stones with irregularly curved lateral faces. The individual paving stones have, on their irregularly curved lateral faces, chains or partial chains of adjoining, spaced apart strip-shaped connection sections that mesh together in the manner of a gear rack with connection sections of adjoining paving stones. This makes it possible to achieve paving connections even with randomly shaped paving stones.

An inventory of industrial mats having different core or internal constructions that are not visible because of the inclusion of side, end, upper and lower components which hide the core or internal construction from view, wherein each mat has an electronic device that indicates what is present in the hidden core or internal construction of the mat, with the electronic device including a processor, storage, and wireless communications circuitry that is configured to transmit identification, location, usage or physical property information of the mats over a wireless telecommunications network. Also, a method for providing an identification of mat properties or usage for an inventory of mats by viewing the information stored on the electronic device or by retrieving over a wireless telecommunications network identification, location, usage or physical property information of the mats from the storage of the electronic device.
