What are epoxy resin systems used for in pipe rehabilitation?

Epoxy resins are used in cured-in-place pipe (CIPP) and lining processes to create structurally sound, corrosion-resistant pipe interiors without excavation.

What advantages do epoxy resins offer over other resin types?

They provide superior adhesion, chemical resistance, controlled curing, and high mechanical strength—ideal for demanding wastewater and industrial environments.

How are curing conditions controlled?

Curing with epoxy resin can be adjusted via temperature or catalysts, ensuring predictable installation and performance.
