Abstract:
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 generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°; wherein the sides of each 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, whereby in use in combination with other flagstones, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighboring flagstone.
Abstract:
The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.

Abstract:
A retaining wall kit is made up of a plurality of molded blocks, some having different thicknesses and some having different lengths. Keyhole-slots may be provided at the rear face of the molded blocks, each keyhole being proportionally sized inwardly of the rear face of the block such that a retaining member fitted within the keyhole-slot projects downwardly from the one molded block to engage the rear face of an adjacent molded block so as to space the molded blocks in a regular sloped position such that the inter section of the front and top faces of each molded block is in a common plane.
Abstract:
An improved curb section of a predetermined length sub-divided into modules by transverse grooves which give the appearance of shorter blocks and provide for fracturing the curb section at those locations. Each module of the curb section includes a rearward fastening projection having a vertical bore for passing a nail to engage the curb section to pavement or other base. Such linear mold sections are all that are required when a curve is dictated. The mold sections are sub-divided into the modules to form the curve. A method of forming the curb section is provided which includes an open frame moving vertically against a platform and mold shoes for pressing down on the concrete when poured in the mold frame, including plugs for forming the tops of the fastening projections. The plugs are removed after the mold frame is lifted, and then the shoes are removed to leave the formed curb sections on the bottom wall.
