IET Coating

IET Coating

IET SYSTEMS Polymorphic Resin is stronger than any other concrete repair or coating product. IET penetrates into the open pores of concrete creating a structural attachment stronger than the concrete matrix itself. The strength of the concrete becomes the limiting factor in the adhesion. It can be used in place of cement and water as the binding agent for any aggregate mix used in concrete. This creates a super concrete that can be used for repairs to damaged concrete or the creation of monolithic structures. Adheres to steel and other metals creating a nearly indestructible coating.

IET SYSTEMS has seven different combinations and unique blends of fillers and state-of-the-art application equipment to create an unsurpassed renovation and protection system for all wastewater processing facilities.
