Publication number: 20140260059Abstract: A building unit including upper and lower surfaces, and a plurality of side surfaces extending between the upper and lower surfaces defining a generally trapezoidal shape in plan view. The unit includes a first pair of the side surfaces, located on opposite sides of the unit and extending non-linearly and generally obliquely with respect to each other in plan view, where each side surface of the first pair has a midpoint bisecting it into two portions. The portions on each side of the midpoint are a 180° rotational image of the other portion about the midpoint. One side surface of the first pair is longer than the other, and the longer side surface includes a midsection of the same length and configuration as the other, shorter side surface. Each of the shorter and longer side surfaces interlocks with either the shorter or longer side surface of another like building unit.Type: ApplicationFiled: March 11, 2014Publication date: September 18, 2014Applicant: Keystone Retaining Wall Systems LLCInventors: Thomas S. Riccobene, Robert A. MacDonald

Publication number: 20140260057Abstract: A building unit has a substantially planar base having an outer periphery including multiple mating sides. Each mating side has at least one “S”-connection, which includes at least one outwardly extending male mating section and at least one inwardly extending adjacent female section. On the base, there are multiple cobbles or raised regions separated by false joints. A first portion of the raised regions are positioned on the male mating sections, respectively and extend to positions proximate to the outer periphery of the base. A second portion of the raised regions are positioned adjacent the female mating sections, respectively and are set back from the outer periphery. Each side of one unit can mate with any side of another like unit. The arrangement results in a surface covering that lacks a discernible pattern.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: Keystone Retaining Wall Systems LLCInventors: Thomas S. Riccobene, Robert A. MacDonald

Publication number: 20140169878Abstract: A permeable surface covering unit comprises a top surface and at least two pairs of irregularly shaped mating sides, one or more passageways extending downwardly from the top surface, and at least one under channel connected to the passageways for retaining liquid, such as storm water. The sides of the unit preferably define an irregular rotational tessellation element. The passageways may comprise gaps or side cavities between units and/or core cavities or other passageways within the unit. Optional undercuts may be provided in the core cavities. Pervious material plugs are cast into the cavities extending into the channel or undercut.
