System and method for preventing or arresting corrosion on infrastructures with an impervious barrier

Abstract

Corrosion on industrial infrastructures can be prevented or arrested using a multi-stage system and method having an optional epoxy primer, a thermoplastic layer, a self-amalgamating water-cure wrap, and a top coat of epoxy. The resulting impervious barrier resists corrosion and withstands abuse from the elements.
