Epoxy Pipe Coating: No-Dig Rehabilitation Guide

How to rehabilitate worn or cracked pipes from the inside — without breaking walls, digging, or expensive construction work.

What is Epoxy Pipe Coating?

Epoxy Pipe Coating (also known as brush coating or spray lining) is a NoDig method of pipe rehabilitation where the inside of the pipe is coated with a two-component epoxy resin. The result is a new, smooth surface that protects the pipe from corrosion and leaks — all without digging.

🎯 When to Use Epoxy Coating?

  • Old metal pipes with corrosion
  • Pipes with minor cracks or leaking joints
  • Pipes under floors, in walls, or hard-to-access locations
  • Renovations where you want to avoid demolition
  • Preventive protection of new installations

The Process

  1. Camera inspection — assess pipe condition and locate problems
  2. Cleaning — pipe is thoroughly cleaned using high-speed method
  3. Drying — pipe must be dry for good epoxy adhesion
  4. Epoxy application — two-component epoxy applied by brushes or spraying
  5. Curing — epoxy hardens (usually 2-4 hours)
  6. Final inspection — camera confirms coating quality

Advantages vs. Pipe Replacement

Aspect Epoxy Coating Pipe Replacement
Duration 1 day 3-7 days

Common Problems and Solutions

  • Epoxy doesn't stick — pipe not clean or dry enough
  • Uneven application — check brush and pipe diameter compatibility

Conclusion

Epoxy Pipe Coating is a smart alternative to expensive pipe replacement. With the right equipment and technique, you can rehabilitate pipelines for a fraction of the cost and time — with 50+ years warranty.
