A block suitable for use in paving, edging or wall applications comprises a lower portion having parallel, substantially vertical side faces that are spaced apart by a first width, and an upper portion having parallel, substantially vertical side faces that are spaced apart by a second width. The second width is smaller than the first width of the lower portion, and the side faces of the upper portion are angled relative to the side faces of the lower portion. The block further comprises a transition portion between the upper and lower portions, having at least one slanted side extending between one or more sides of the lower portion and one or more sides, respectively, of the upper portion.

Disclosed is a universal mold having removable arm members and socket members that can be configured to fabricate the border blocks, the corner blocks and the interior blocks.

A hard pavement construction method for natural groundwater recharge, comprising the following steps: drilling to an underground shallow sand zone water storage layer on a flattened earth floor, filling holes with sand, inserting rod-shaped tools into the holes filled with the sand, pouring concrete to form a concrete foundation layer with a flat surface, removing the rod-shaped tools, filling the holes with the sand to be flush with a plane of the concrete foundation layer, sanding and compacting on the concrete foundation layer, directly arranging pavement bricks on a sand surface in an unbonded manner to form a hard pavement, and enabling rain and snow water on the hard pavement to pass through cracks of the pavement bricks, rapidly and naturally recharge to the underground shallow sand zone water storage layer via the holes and slowly permeate to an underground deep sand zone water storage layer.

Various monolithic pavers are one-piece pavers with no seams, joints, or connections. A monolithic paver can be formed via three dimensional (3D) printing or molding. The monolithic paver is designed to carry applied loads to paver support(s) via structural members of the monolithic paver. The monolithic paver is formed to include parallel structural members that are spaced with gaps there between. The parallel structural members include top flanges and webs. The parallel structural members can also include bottom flanges. Moreover, the monolithic paver can have exterior sides that have tongues and grooves formed there along; tongues can be formed along adjoining exterior sides of the monolithic paver.

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.
