A method of anchoring multiple tie-downs of a pool cover of an in-ground swimming pool, which is surrounded by stone or concrete pavers, uses a tubular footing member with multiple flange plates laterally extending along its length. The flange plates include a base flange plate which enclosed the distal end of the footing member and one or more medial flange plates surrounding the tubular circumference of the footing member between its proximal and distal ends. The proximal end of the footing member is open and this proximal opening has interior threading which conjugately mates with the threaded shank of a coupling screw to which a tie-down is anchored.
