Abstract

An adhesive used in underground applications where vegetation is present wherein the adhesive has been doped with a material or materials that deter the growth properties of adjacent vegetation. The materials can include Zinc, Copper Sulfate, Copper Oxide, as well as sulfates of Zinc, Manganese, and Nickel, in quantities that will repel or deter the advancement of roots and invasive vegetation into fittings and joints in an underground system. The adhesive is used to bond a conduit and a fitting in an air-tight and water tight seal, and the inclusion of the root deterrent material resists invasion of nearby roots into the piping. The root deterring supplements to the adhesive to not degrade the performance of the adhesive and actually repel roots in the vicinity of the materials.

Claims

1. An adhesive compound comprising:

a base adhesive comprising unvulcanized rubber in a solvent selected from hexane and heptane, and a secondary constituent selected from isopropanol and ethanol; and

an additive including nickel and zinc incorporated into the base adhesive to form a compound, the additive selected for its vegetation deterring properties;

wherein the additive to base adhesive is in the range of 0.0025;

1 to 0.06;

1.

2. The adhesive of claim 1, wherein the additive includes manganese.

3. The adhesive of claim 1, wherein the additive includes copper sulfate.

4. The adhesive of claim 1, wherein the additive includes copper oxide.
