1. A weighted elastomer comprising:
- an elastomer; and
a weighting agent attached to an outer surface of the elastomer, wherein the weighting agent comprises a material selected from the group consisting of pumicite, perlite, and a combination thereof, wherein the weighting agent is attached to the outer surface of the elastomer using an adhesive, wherein the adhesive comprises at least one adhesive selected from the group consisting of a water-based acrylic paint, an oil-based paint, and an oil-based primer,wherein the weighted elastomer has a specific gravity of at least about 1.1.
