Can the west coast tiles be laid on top of grass in a backyard for a backyard kids play swing set? Do these tiles interlock somehow? How do they attach to each other and would grass grow between the tiles? Thank you.

Our Paver Tiles - West Coast can be laid over grass. When installing these tiles over grass it is recommended that a weed fabric be placed under the tiles to prevent grass from growing between the tiles. The tiles do not interlock to each other but can be glued together with a polyurethane seam sealer glue.
