A paving system is disclosed that includes a first paving stone having a virtual perimeter outline and a plurality of first physical sides, the virtual perimeter outline having a plurality of segments, where each segment of the plurality of segments corresponds to two or more of the first physical sides, and wherein any vertex between two adjacent segments is separated from any vertex between two adjacent first physical sides by a predetermined distance. A second paving stone having the virtual perimeter outline and a plurality of second physical sides, where each segment of the plurality of segments corresponds to two or more of the second physical sides, and wherein any vertex between two adjacent segments is separated from any vertex between two adjacent second physical sides by a predetermined distance. The plurality of first physical sides is different from the plurality of second physical sides.

An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.

A paving slab. The paving slab has a unitary body made of concrete-based material, the body having sidewalls extending between top and bottom faces, providing the body with a thickness. The top face is provided with longitudinal false joints defining rows extending from a first to a second side of the unitary body. The first side has a staggered outline and the second side has a stepped outline, the first and second sides being able to engage with respective first and second sides of an adjacent slab shaped as the paving slab, but rotated by 180 degrees. When several of the slabs are assembled on a surface, it creates an illusion that the surface is covered by individual plank pavers randomly assembled.

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.

An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.

A method for forming a permeable pavement system includes installing a plurality of preformed paving blocks to form a paving surface. Each of the preformed paving blocks includes an upper surface, a lower surface generally parallel to and spaced apart from the upper surface, and a pair of parallel ducts extending horizontally through the block between the upper surface and the lower surface. After forming the paving surface, the method further includes inserting a transmission device through at least one of the parallel ducts of each paving block of the plurality of preformed paving blocks. Finally, the method includes using a controlling device to control the transmission device such that the temperature of the plurality of preformed paving blocks is automatically maintained at a predetermined range, wherein the controlling device selectively adjusts one of electrical current through the transmission device or circulation of a fluid through the transmission device.

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.

A method includes compacting an aggregate bed to obtain a compacted tile bed surface of a tile bed; installing a plurality of porcelain tiles between a plurality of spacers on the compacted tile bed surface, wherein each of the plurality of spacers comprises: a base component; and a plurality of vertical components supported by the base component, each vertical component comprising a tapered shape on an interior end of the vertical component; adding a polymeric sand composition to a first joint in an intermediate porcelain tile installation to obtain a first joint-filled porcelain tile surface; compacting the first joint-filled porcelain tile surface; and activating the polymeric sand composition in the first joint-filled porcelain tile surface.

A tile for cladding and paving comprises a single body made from a ceramic material. The tile comprises a main area that has a substantially polygonal plan having between five and ten sides and at least one additional area located on at least one side of the main area. Each additional area has an irregular polygonal plan, such that one of the longer sides of the additional area faces one of the sides of the main area.
