Abstract:
1. A method of installing an interlocked floor system, the method comprising: providing multiple polymeric panels molded as an integral body having a planar top surface and a grid structure supporting the top surface and multiple interlocking side surfaces; each interlocking side surface having upwardly and downwardly facing steps, at least one of the downwardly facing steps have a convex projection on a bottom surface, at least one of the upwardly facing steps have a concave mating dimple on an upper surface; an over hang ledge formed as an extension of the planar top surface, thereby forming a cavity between the over hang ledge and the upper surface of the upwardly facing step; an under hang ledge formed in a top surface of the downwardly facing step allowing the downward facing step of a first panel to fit within the cavity of a second panel; and whereas the steps of the side surfaces of the first panel interlock to complementary steps of the second panel, held in place by the convex projections and the mating concave dimples; removing a top portion of soil; backfilling with a backfill material to replace the top portion of soil; preparing a surface over the backfill material; compacting the surface; installing a cover material over the surface; joining the multiple polymeric panels and installing the multiple polymeric panels over the cover material; installing spikes through holes in a subset of the multiple polymeric panels; and deploying a synthetic turf over the multiple polymeric panels.
