Articulating composite surface covering mat and method of making
An articulating composite surface covering mat and process of forming the mat which has multiple units having a regular, natural or irregular appearance, and each unit a flexible geogrid extending therethrough. A method of forming the mat includes forming the mat upside-down on a bottom surface of a bottom mold, placing the top mold over the bottom mold to form the mold assembly, locating a geogrid in the mold assembly, latching the mold assembly together with magnets, and adding the filler to the mold assembly.
1. A process for the formation of an articulating composite surface covering mat which comprises spaced apart units that are held together by a geogrid, the process comprising the steps:
disposing a bottom mold on a substantially level surface, wherein the bottom mold has a generally planar bottom surface that defines the top surface of the formed mat, and transverse walls extending from the bottom surface of the bottom mold;
locating a geogrid such that the geogrid extends into each of the spaced apart units to be formed;
placing a top mold over the bottom mold to form the mold assembly, wherein the top mold has a generally planar top surface and transverse walls extending therefrom;
sealingly engaging at least a portion of the transverse walls of the top mold with corresponding transverse walls of the bottom mold;
latching the top mold to the bottom mold into a sealed engagement with a magnetic latch that includes at least one first magnet located in the top mold and a second magnet located in the bottom mold; and
adding a filler to the mold assembly through openings in the top mold.
2. An articulating composite surface covering mat, comprising:
multiple units having a natural or irregular appearance and formed of a filler, each having an irregular peripheral shape as viewed in plan view;
a flexible geogrid extending through and between each of the multiple units to define the mat;
a peripheral surface of the mat defined by segments of peripheral surfaces of at least some of the multiple units, the peripheral surface of the mat having at least three sides, wherein at least two of the at least three sides comprise the segments of the peripheral surfaces of the multiple units defining S-curve geometry, wherein at least two of the three sides of the mat has a center point, and a first segment of the side is a 180-rotation of a second segment of the side about the center point.
