Abstract: A heatable module for use in constructing a pathway for traffic comprises a base member having a perimeter edge. A top plate is securable to the base member in overlying relation to the top surface of the base member. An electrically powerable heater member retained by at least one of the base member and the top plate. To form a heatable pathway for traffic, the modules are placed in perimeter-edge-to-perimeter-edge relation one to the next.

Abstract: A heatable pathway system for traffic comprises a first module having a first electrically powerable heater member and a second module having a second electrically powerable heater member. The first module and the second module are each installable in place to form a heatable pathway system for traffic. An electrical power controller circuit has a first power output connected in power supplying relation to the first electrically powered heater member and a second power output connected in power supplying relation to the second electrically powerable heater member. The electrical power controller circuit is operable to provide electrical power from the power outputs in a heating cycle that comprises a first heating sub-cycle and a second heating sub-cycle such that, during a heating cycle, a first one of the electrically powerable heater members is on and a second one of the electrically powerable heater members is off during the first heating sub-cycle, and the second electrically powerable heater member is on and the first electrically powerable heater members is off during the second heating sub-cycle.

Abstract: A permeable surface covering unit comprises a top surface, a bottom surface and at least two pairs of sides. A cavity is formed in the unit from the top surface to the bottom surface, and has side walls. The cavity may be a side cavity between units and/or a core cavity within the unit. An undercut is provided in the cavity. Pervious material plugs fill the cavity and extend into the undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces.
