Abstract:
A concrete casted paving stone of rectangular shape is described and has two pairs of opposed parallel side walls. In a first of the two pairs of side walls, an engaging projection is formed in one side wall and a through slot in the other side wall for receiving the stone-engaging projection of another paving stone therein. The second pair of opposed parallel side walls each have a slot and a further stone-engaging projection in a section thereof. The stone-engaging projections of the second pair of side walls are disposed adjacent the side wall of the first pair which contains the slot and the slot extends through the rear wall of these stone-engaging projections. The paving stone may be used as a permeable paving stone wherein to evacuate water from an upper surface of a paved surface into the underlying support bed.
Abstract:
A kit and system for constructing structures including at least one core block, at least one fascia block that connects to the core block by mounting a shelf that extends from a face of the core block with a cut-out section of a face of the fascia block, such that the face of the core block and the face of the fascia block form a gap therein between.
Abstract:
A culvert structure interconnectable with interconnectable paver blocks. The culvert structure comprises an elongated rigid casing having a bottom wall, opposed parallel vertical side walls, and an open top end. One of the vertical side walls has at least one projection formation for interconnection with a slot of adjacent ones of the paver blocks in a paved surface formed by the paver blocks. The other of the vertical side walls has a slot formation for interconnection with a blocks engaging projection of adjacent ones of the paver blocks in the paved surface. The bottom wall has passage means for the evacuation of water therethrough and a support structure connected to the rigid casing for supporting a grate over the open top end.
