A curbing system comprising:
- an outer shell constructed of a durable synthetic material comprising a U-shaped continuous channel defining a base and a pair of sidewalls that extend upwardly from the base, the base and the sidewalls constructed from a single continuous synthetic material piece and defining an enclosure that extends from the base to respective upper edges of the sidewalls;
- a securing medium that interconnects the base with a ground surface;
- a rigid filler material, contained within the enclosure defined by the base and the sidewalls, the filler material being a hardenable filler that changes from a liquid to a solid phase at predetermined times, the upper edges being constructed and arranged to allow location of the filler in the liquid phase into the enclosure;
- and
- wherein the U-shaped channel includes a pair of opposing ends and wherein only the rigid filler material is in contact with the sidewalls within the enclosure between the base and the upper edges at locations between each of the opposing ends.
