    Abstract: A connection surface disposed on a face of a structural unit comprises a first segment having a three dimensional surface profile including a plurality of positive outer surfaces extending outwardly along a normal direction from a plane and a plurality of negative outer surfaces extending inwardly along the normal direction from the plane, wherein at least two of the plurality of positive outer surfaces are separated from one another along both vertical and horizontal directions and at least two of the plurality of negative outer surfaces are separated from one another along vertical and horizontal directions. A second segment opposes the first segment with respect to an axis, wherein the second segment is a substantial reflection of the first segment across the axis, but reversed along the normal direction.

    Abstract: A wall block comprises an upper surface and an opposed lower surface. A front face and an opposed back face, and a first side face and an opposed second side face, are disposed between the upper surface and the lower surface. The first side face and the second side face generally extend from the front face to the back face. The block includes one or more features that define a horizontal alignment direction. The front face extends from the first side face to the second side face generally along a direction that is slanted with respect to the horizontal alignment direction.

    Abstract: 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. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces. A permeable surface embodiment comprises a combination of pervious and impervious units, wherein the ratio of permeable to impermeable units and resulting surface absorption rate may be adjusted.

    Abstract translation: 可渗透表面覆盖单元包括顶表面和至少两对不规则形状的配合侧面，从顶表面向下延伸的一个或多个通道，以及连接到通道的至少一个下通道，用于保留液体，例如雨水。 单元的侧面优选地限定不规则旋转镶嵌元件。 通道可以包括在单元之间的单元和/或芯空腔或单元内的其它通道之间的间隙或侧腔。 可选的底切可以设置在芯腔中。 渗透材料塞被浇注到延伸到通道或底切中的空腔中。 由此，塞子如铆钉锁定在空腔中，并抵抗机械或液压力的移动。 可渗透表面实施方案包括渗透和不渗透单元的组合，其中可以调节可渗透单元和不可渗透单元的比率以及所得到的表面吸收速率。
