A deck module includes deck panels having a plate shape extending in a first direction and having deck grooves formed in both side surfaces thereof in the first direction, a bottom structure disposed on lower portions of the deck panels in a second direction crossing the first direction, and quick clip modules connected to a side surface of the bottom structure, wherein the quick clip modules comprise quick clip bases extending in the second direction, quick clip protrusions protruding from the quick clip bases in a third direction orthogonal to the first direction and the second direction and having protrusion portions formed at ends of the quick clip protrusions to protrude in the second direction and correspond to the deck grooves, and quick clip supports protruding from the quick clip protrusions in the first direction.

A module for use in constructing a pathway for traffic comprises a base member that defines a lateral groove disposed at its perimeter edge and extending along a first end, and a tongue structure disposed at its perimeter edge and extending along a second end. The tongue structure is received in the lateral groove and comprises a plurality of tongue portions that includes a first type of tongue portion and a second type of tongue portion disposed in alternating relation along the length of the tongue structure, to thereby define a throughpassage for receiving a securing rod. The first and second tongue portions have no vertical overlap one with the other. To form a pathway for traffic, the modules are placed in perimeter-edge to perimeter-edge relation, with the tongue structure of the modules inserted into the lateral groove of an adjacent module, and are secured together by the securing rod.

A grass protection mat comprises a body where grass passing spaces are continuously arranged and an outer frame comprising four frames formed in four directions to finish an outer edge of the body, wherein the grass protection mat further comprises at least one hook fastener which horizontally protrudes from a first lateral frame of the outer frame toward a second lateral frame of an outer frame of a neighboring grass protection mat, and wherein the at least one hook fastener is fastened to at least one fastening hole provided in the outer frame of the second grass protection mat adjacent to the first lateral frame and corresponding to the hook fastener of the grass protection mat.

A dual-unit paving system for covering a surface has pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are configured to be matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly allows forming rotational tessellations. The first and second units are also shaped and configured to be matingly engageable so as to form horizontally aligned tessellations, and also vertically aligned tessellations.
