Advantages of Cured-in-Place-Pipe (CIPP) Lining  


Commonly referred to as CIPP lining, Cured-in-Place-Pipe lining is a trenchless pipe restoration technique that effectively preserves existing pipes that have been damaged by cracks, leaks, rust, or intruding roots. In this method, a new pipe is created within the old and damaged pipe using epoxy and mesh lining. Cured-In-Place-Pipe (CIPP) lining works with a wide range of piping materials including PVC, cast iron, galvanized steel, corrugated metal, concrete, and clay. This technique is extremely popular because it lasts for many years and causes little to no damage to a property.  

Understanding the Process   

The best thing about pipe relining is that it requires no digging as the entire lining work is performed below the ground. Before the start of the lining process, a video inspection is done to find out the location of damage. Based on the findings of this inspection, a restoration plan is created.   

Once the location of the damage is determined, the following tasks are performed to prepare the pipe for lining.  

  • Flushing out debris and removing roots from the pipe. 
  • If necessary, a sewer bypass system is created so that water or sewer can be re-routed to other pipes nearby during the lining process.   
  • To ensure that the pipes remain debris and water free during the process, it may be necessary to set up and run a vacuum truck.  

Finally, the lining process can start after all the above mentioned work is done. The old and damaged pipes are lined using high strength woven fibres saturated with special types of epoxy resins. Then the lining is inserted into the existing pipe addressing the problem area. The liner is then exposed to ultraviolet light (UV) or heat for curing and hardening. UV curing is more popular because it is stronger, significantly more durable, and requires less time. Once the liner is hardened, a corrosion resistant, tight fitting, continuous, and new pipe is formed within the old pipe.  

Benefits of CIPP Lining 

Compared to highly disruptive traditional restoration techniques that require digging up and rebuilding the pipe system, CIPP lining offers numerous benefits.    

  • Experienced CIPP lining professionals can complete this entire restoration process in just a few hours, bringing the pipes to almost their new condition.  
  • Compared to replacement of old, damaged pipe with a new one, pipe lining can save up to 75% in costs. The labour cost gets reduced significantly because the trenchless process requires less time to complete.   
  • CIPP lining can conform to all shapes of pipes and is compatible with a wide spectrum of piping materials.  
  • This zero-digging methodology causes no disruption to the property and saves both time and money. 
  • The strong epoxy cured coating makes the repaired pipe resistant to corrosion, damp, and regular wear and tear. When done in the right way, CIPP lined pipelines can last up to 100 years.  

CIPP lining has no noticeable downsides. However, if your pipeline has become irreversibly damaged, it may be too late to rehabilitate the system using this methodology.
