Abstract: An improved anti-corrosive material used to protect buried and submerged metallic structure such as conduits from corrosion. The anti-corrosive material is comprised of a layer of polyolefin having a plurality of microperforations formed therein. The anti-corrosive material is preferably comprised of a low density polyethylene having characteristically strong tensile strength and elongation properties to provide conventional protection from soil, water, air, or other potentially damaging elements. The microperforations allow the anti-corrosive material to be utilizeded with cathodic protection systems to provide for a significant reduction in the amount of electrical current required to achieve cathodic protection. The present invention can be used to control corrosion without costly and easily damaged coatings or adhesives; and can be applied to metallic structures in the field prior to installation.
