(57) There is described a system for preventing accumulation of meltable precipitation on a surface. The system generally has: a concrete slab having a slab body with a top surface opposed to a bottom surface, the slab body having electrically conductive concrete; a plurality of elongated electrodes within said slab body, a first set of said elongated electrodes being spaced apart from one another proximate to said top surface and a second set of said elongated electrodes being spaced apart from one another away from said elongated electrodes of said first set, the elongated electrodes of the first set being interspersed with the elongated electrodes of the second set; and a voltage source being electrically connected to the elongated electrodes and being operable to apply a voltage to said elongated electrodes, thereby generating heat within said slab body for melting said accumulation on said top surface.
