Sewer Network Lining – Non-Excavation Pipe Restoration

Sewer Network Lining – Non-Excavation Pipe Restoration

Sewer network lining is an innovative and non-invasive solution for the restoration of drainage and sewer pipes, eliminating the need for time-consuming excavation work. This process creates a new inner surface within the existing pipe, restoring functionality and structural strength without requiring a complete replacement.

By applying a durable and resistant liner, this method corrects cracks, leaks, and other structural damage, ensuring a more efficient, watertight, and long-lasting sewer system.

How Does Sewer Network Lining Work?

The internal pipe lining process follows a precise methodology to ensure effective repair while minimizing disruptions:

1. Initial Pipe Inspection

✔ A specialized plumber creates a small access point in the pipe and inserts a scope (probe) to inspect the interior.
✔ Using video inspection technology, the professional analyzes the pipe's condition, identifying issues such as cracks, wear, leaks, and joint misalignment.

2. Pipe Preparation and Liner Insertion

✔ After inspection, the pipe is cleaned to remove debris, grease, or accumulated waste.
✔ A flexible liner impregnated with special resin is inserted into the pipe, adapting to its internal shape.

3. Expansion and Curing of the Liner

✔ The liner is inflated inside the pipe, molding itself to the inner walls to cover any failures and reinforce the structure.
✔ After the necessary curing time, the resin hardens, forming a new, smooth, and durable internal pipe lining.

4. Final Inspection and Completion

✔ Once dried, the team performs a final video inspection, ensuring that the pipe is fully restored and functional.
✔ The result is a renewed, watertight pipe with improved structural integrity.

Advantages of Sewer Network Lining

Internal pipe lining offers significant benefits compared to traditional sewer repair methods:

✔ No excavation required – Avoids time-consuming construction and disruptions in public or residential areas.
✔ Quick restoration – The process can be completed in just a few hours, minimizing sewer service interruptions.
✔ Extended durability – The new internal layer prolongs the lifespan of the pipes and resists leaks and cracks.
✔ Improved hydraulic flow – The new lining creates a smooth surface, reducing waste buildup and preventing blockages.
✔ Cost-effective solution – Significantly reduces costs related to labor, demolition, and full pipe replacement.
✔ Lower environmental impact – With no need for excavation or removal of old pipes, this method is eco-friendly and sustainable.

When Should You Consider Sewer Network Lining?

This technique is recommended for:

✔ Aging pipes with cracks or signs of wear;
✔ Water infiltration into the ground due to sewer system failures;
✔ Sewer pipes with misaligned joints or structural weaknesses;
✔ Repairing sewer problems without needing to excavate streets or indoor areas;
✔ Preventing future issues by strengthening the system’s durability and resistance.
