Abstract: A dual-unit paving system for covering a surface. The system comprises pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are configured to be matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly allows forming rotational tessellations. The first and second units are also shaped and configured to be matingly engageable so as to form horizontally aligned tessellations, and also vertically aligned tessellations.

Abstract: A paving slab is provided. 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.

Abstract: An artificial stone is disclosed for use in creating a covering for a supporting surface. The artificial stone includes a body for placement on the supporting surface, which is shaped for mating engagement with like stones with intermediate perimeter joints to produce a continuous surface covering. The stone has a facing surface on the body, which facing surface has a contour defining a surface area and is subdivided by at least one simulated joint into a major surface portion and at least one minor surface portion. The major surface portion is free of simulated joints and extends over at least about 60% of the total surface of the facing surface. The stone further includes at least one perimeter recess in the body for generating a gap between the stone and another like stone in mating engagement therewith, which gap is wider than adjacent the adjoining perimeter joint.

The dry-cast concrete block comprises a surface to be exposed, at least a portion of the surface having a cast texture with a natural stone appearance. The cast texture may have a surface level difference of greater than 4 mm. In one example of implementation, the dry-cast concrete block may be a paving unit, in which case the surface level difference may be greater than 6 mm, such as between 6 mm and 12 mm. In another example of implementation, the dry-cast concrete block may be a wall construction unit, in which case the surface level difference may be greater than 15 mm, such as between 15 mm and 25 mm. Each of a plurality of points of the cast texture may define a respective texture angle between 75° and 90°. The cast texture may comprise at least one valley each having a respective depth greater than 4 mm. A process for manufacturing such a concrete block is also provided.

Abstract: A coloring system and a manufacturing process for coloring artificial covering stones are provided. A board layout represents a board of artificial covering stones. Several natural stone color patterns are provided, each being different from one another. The natural stone color patterns are associated with selected artificial stones of the board layout. Graphic parameters represent the natural stone color and are converted into coloring instructions. A conveyor conveys the board of artificial covering stones, and a positioning system determines respective positions of the artificial covering stones of the board, relative to a reference position. An in-line coloring device colors the artificial covering stones with the natural stone patterns, according to the coloring instructions and to the positions of the artificial stones. The selected artificial stones colored by the system are thus different from other stones of the board, and have a distinct, natural random-look.
