Brick/block/paver unit and method of production therefor

Abstract

In a method of splitting a base block to form brick, block or paver units, a cementitious or stone base block having a first side, an opposed second side and a plurality of perforations is provided. Each perforation extends through the base block from the first side to the opposed second side, the plurality of perforations creating a splitting path in the base block. The splitting path has a cross-section consisting of from 70-50% by area of perforated regions and from 30-50% by area of unperforated regions. The base block may be split along the splitting path by a light shock to produce the brick, block or paver units. A wide variety of consistent and reproducible facing surfaces on brick, block and paver units may be produced that integrate texture, pattern, configuration and shape.

Description

FIELD OF THE INVENTION[0001]The present invention is related to building units, particularly to brick, block and / or paver units.BACKGROUND OF THE INVENTION[0002]Brick, block and paver units are typically made by various known methods from stone, cement or other stone-like materials. Such units are useful in the construction of various structures, for example, walls, driveways, etc., and may be molded from processed or reprocessed materials or cut from natural stone. Since the available supply of good grade natural stone is diminishing, there is considerable interest in the art for producing high quality, natural looking products from molded materials. However, the ones presently available on the market have a rough unfinished appearance resembling broken stone or concrete due to the detailing processes. Detailing processes generally involve splitting and pitching of the unit to produce faces having unpredictable and uneven surfaces. The lack of reproducibility and unpredictability o...
