How Inversion Lining Works: Simple and Technical Explanation
Pipe relining technology has revolutionised how plumbers repair damaged drains without excavation. One standout method used widely in Australia is Inversion Lining. At CIPP Global, we're experts in this trenchless pipe repair method. Here's everything you need to know.
What is Inversion Lining?
Inversion lining, also known as CIPP (Cured-In-Place Pipe) inversion, is a non-invasive technique that repairs pipes from the inside. It eliminates the need to dig trenches, making repairs quicker, safer, and less disruptive.
How Does Inversion Lining Work?
Simple Explanation:
Imagine turning a sock inside-out—this is precisely how inversion lining works. A flexible resin-saturated liner (like a sock) is pushed through the damaged pipe using pressurised air from an inversion drum. The air pressure flips the liner inside-out, pressing the resin-coated liner firmly against the existing pipe walls. Once cured, it forms a strong new pipe inside the old one.
Technical Explanation:
The inversion lining process involves the following steps:
-
Inspection: A CCTV drain camera checks the condition of the damaged pipe.
-
Preparation: The felt liner is saturated with an epoxy or polyester resin.
-
Inversion Drum Setup: The liner is loaded into an inversion drum, and the drum is sealed.
-
Air Pressure Inversion: Air pressure within the inversion drum forces the liner through the pipe. The internal air pushes the liner outwards, causing it to invert and adhere tightly against the interior pipe surface.
-
Curing: The liner is cured using either ambient air temperature or hot water/steam, hardening the resin to create a robust new pipe lining.
-
Final Inspection: The repaired pipe is inspected again to ensure quality and compliance.
Pros of Inversion Lining:
-
No excavation required: Saves landscaping, roads, and structures.
-
Cost-effective: Reduced labour, equipment, and restoration costs.
-
Durability: Provides a long-lasting solution resistant to corrosion and tree roots.
-
Fast Repairs: Often completed in just hours rather than days.
-
Minimal Disruption: Less downtime for properties or businesses.
Cons of Inversion Lining:
-
Pipe Diameter: Limited effectiveness for very large diameter pipes.
-
Existing Pipe Condition: Pipes must be structurally stable enough to support the liner.
-
Complexity: Requires professional training and specialised equipment.
