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 paver system configured for installation on an existing hardscape. The paver system includes paving stones having a concave bottom surface. The concavity intersects edges of the paver to enable runoff to flow beneath and between the pavers. The concavity may also reduce the weight and material requirements of the paver while also increasing the strength of the paver. An underlayment is provided that includes a bottom surface with a plurality of intersecting channels. The underlayment is bonded to an existing hardscape, such as a concrete pad, and the pavers are arranged and bonded to the top surface of the underlayment. Rainwater and other runoff are allowed to flow between and under the pavers through the concave bottom portions thereof and through the channels in the underlayment. The paver system provides a strong, stable installation with sufficient drainage to resist damage caused by retained water.

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.

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.

A modular roundabout or traffic calming system with interlocking connectors and a method of installation utilize a plurality of boards arranged in a pattern on a ground surface at an intersection of vehicle roadways, the pattern including one or both of a central island and a splitter island. At least some of the boards forming a perimeter of the pattern are affixed to the ground surface. At least some of the boards forming interior boards are interconnected at adjacent edges with connectors. The connectors can include a hinge joint so that the interconnected boards can be folded or rolled. A kit for a modular roundabout or traffic calming system is also provided.

A modular mat assembly formed from recycled material and anchored to the ground to form a sidewalk having replaceable sections and enclosed LED lighting for night time illumination.

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

A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.
