Any floor with dissipative/conductive properties that is attached to either electrical or earth ground.
Grounding of conductive or static-dissipative floors is usually achieved by physically attaching the ESD flooring material— conductive or dissipative epoxy coating, conductive or dissipative carpeting or carpet tiles, conductive or dissipative vinyl tiles or sheet goods, conductive or dissipative rubber tiles or sheet goods—to a certified ground connection using copper strips or grounding wires.
The most common methods of grounding involve the combination of conductive adhesive, for securing the floor and electrically unifying all tiles in the installation, and copper strips attaching the adhesive to the electrical ground connection in a building.
