What is Drain Rehabilitation?

Drain rehabilitation is the process of repairing, restoring, or improving damaged or decaying and ageing drainage systems without necessarily replacing them entirely. Over time, it is not unusual for drains to develop problems such as cracks, blockages, corrosion, root intrusion, or structural collapse. As an alternative to digging everything up, which can prove to be expensive and disruptive, robotic, trenchless and (No-Dig) rehabilitation focuses on fixing the existing system so it works properly again.

Common Drain Rehabilitation Applications

• Cleaning and descaling: Removing buildup, grease, or debris to restore flow.
• Patch repairs: Fixing small sections of damage inside the pipe.
• Lining (CIPP – Cured-in-Place Pipe): Inserting a flexible liner coated with resin into the pipe, which hardens to form a new pipe within the old one.
• Pipe bursting: Breaking the old pipe while simultaneously pulling in a new one.
• Sealing joints: Preventing leaks and groundwater intrusion.

Benefits of Using Drain Rehabilitation

• Avoids major excavation (less disruption to roads, homes, gardens)
• Extends the lifespan of existing drainage systems
• Reduces costs compared to full replacement
• Improves flow and prevents future issues.
• 
  

In short, drain rehabilitation is about fixing what’s already there rather than starting from scratch.

Using Robotics For Sewer Rehabilitation

How it works

1. Inspection
   Using a remote camera-equipped robot surveys the pipe to locate cracks, leaks, root intrusion, or collapsed sections.
2. Targeted repair
   Depending on the issue identified, the robot can:

• Grind away protruding tree roots or debris
• Cut out damaged pipework sections or obstructions
• Apply resin or patches to seal cracks
• Reopen blocked lateral connections (small branch pipes)

Reinforcement
In a select number of cases, robotic systems prepare the pipe for lining methods like Cured-in-Place Pipe (CIPP), ensuring the liner bonds properly.
