The panels, once locked together, have little movement along their x, y or z axis. ## Claims ### Claim 1 A large-area protective covering system comprising: a plurality of panels wherein each of the panels comprises: a flat upper surface; a grid-pattern internal structure; a lower surface a first side having a first side-locking system; a second side having a second side-locking system, for operative engagement with a first side-locking system of an adjacent panel; a first end having an first end-locking system; and a second end having a second end-locking system, for operative engagement with a first end-locking system of an adjacent panel, wherein said grid-pattern internal structure provides enhanced weight distribution and strength to the panels and the side-locking and end-locking systems on each of the panels are positioned so as to permit adjacent panels to be locked together, and wherein the internal structure is a honeycomb pattern filled with an insulating material. ### Claim 2 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein each of the locking systems comprises a projecting member and a receiving member which are adapted for operative engagement with a receiving member and a projecting member from an adjacent panel, respectively. ### Claim 3 (depends on 1) The large-area protective covering system as claimed in claim 1, wherein said insulating material provides an insulation R-factor greater than 1. ### Claim 4 (depends on 1) The large-area protective covering system as claimed in claim 1, wherein said insulating material provides an insulation R-factor greater than 2. ### Claim 5 (depends on 1) The large-area protective covering system as claimed in claim 1, wherein said insulating material provides an insulation R-factor greater than 4. ### Claim 6 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein the large area panels are installed in a grid configuration. ### Claim 7 (depends on 6) The large-area protective covering system as claimed in claim 6 wherein the sides and ends of the panels are in essentially contiguous contact with each other. ### Claim 8 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein the large area panels are installed in a staggered configuration. ### Claim 9 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein each of the panels covers a surface area of at least 16 square feet. ### Claim 10 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein each of the panels covers a surface area of at least 32 square feet. ### Claim 11 (depends on 1) The large-area protective covering system as claimed in claim 1 comprising at least 50 of the panels. ### Claim 12 (depends on 1) The large-area protective covering system as claimed in claim 1 wherein the panels are constructed of polyethylene, polypropylene, recycled or virgin plastic material, or combinations thereof. ### Claim 13 (depends on 1) The large-area protective covering system as claimed in claim 1, wherein said panels further included reinforcing braces located on the sides and ends of the panels. ### Claim 14 (depends on 13) The large-area protective covering system as claimed in claim 13, wherein said reinforcing braces are made of aluminum or another metal. ### Claim 15 (depends on 1) The large area protective covering system as claimed in claim 1, wherein said lower surface is flat. ### Claim 16 A method for protecting a surface comprising installing a plurality of essentially identical large-area panels each of which large-area panels has an essentially flat upper surface; a grid-pattern internal structure; a lower surface; a first side having a first side-locking system; a second side having a second side-locking system; a first end having an first end-locking system; and a second end having a second end-locking system, wherein the internal structure is a honeycomb pattern filled with an insulating material, and wherein the installation comprises: a) placing a first panel on a surface to be protected; b) installing a second panel with the first end-locking system of said first panel in operative contact with the second end-locking system of the second panel, and sliding the second panel until the ends of the two panels are in contiguous contact with each other and the sides of the panels are essentially in alignment with one another; c) repeating step b) as often as required to establish an end-to-end row of large-area panels which are in end-to-end alignment with each other; d) installing a further panel by placing the first side-locking system of the further panel in operative contact with the side-locking system of the panels of the end-to-end row of large area panels, wherein the further panel is in side-to-side alignment with the end of any of the panels of the adjacent end-to-end row of large-area panels; e) installing an additional panel by repeating step d) and by placing the first end-locking system in operative contact with the second end-locking system of the further panel; f) repeating step e) as often as required to establish a second end-to-end row of large-area panels adjacent to the first end-to-end row of large-area panels; and g) repeating steps d) to f) in order to establish a series of end-to-end rows of large-area panels, wherein each of the rows is operatively connected to an adjacent end-to-end row of large area panels. ### Claim 17 (depends on 16) The method of claim 16, wherein said installation comprises at least 50 large-area panels. ### Claim 18 (depends on 16) The method of claim 16, wherein said panels have a minimum size of 10 square feet.
