  • Movable surface paving apparatus and method for using the same
    Patent number: 5342141
    Abstract: A surface paving apparatus (10) and a method for using the apparatus is disclosed herein. The apparatus is comprised of a mesh material (12) having parallel ribs (14) attached, laid upon a surface to be paved. A paving material (16) with grooves (24) cut into its underside is then placed upon the mesh material (12) such that the ribs (14) on the mesh material (12) frictionally engage the grooves (24) on the paving material (16). The frictional engagement between the grooves (24) and ribs (14) is stable enough to render the paving surface laterally immovable from any direction. The surface paving apparatus (10) can also be disassembled and moved, should this be desired.
