Sewage management in Melbourne is done via underground pipes to prevent groundwater contamination by toxic wastes. These underground pipes degrade from the inside over time and can form cracks or leaks. The primitive way of repairing these cracks is to dig the ground, take out the entire pipeline system and install new pipes. This procedure was time-consuming and costly sewage relining Melbourne.

Modern technology and precision instruments are making pipe repairing a lot easier in the form of pipe relining. Companies like sewage relining, Melbourne is revolutionizing this industry. In this article, we will be getting to know about what sewer relining actually is and what are the different steps involved. 

What is Sewer Relining?

Sewer pipe relining is a pipe repairing process that completely eliminates the requirement for taking the pipe out of the ground and then replacing it with newer parts. In this process, a narrow secondary pipe is fitted within the existing pipe where the crack or damage has occurred. The secondary pipe or the pipe liner is a flexible part that is covered with a resin that hardens within the pipe thus sealing it completely from the inside. This process requires less effort and can be done by experts from relining Melbourne company. 

What are the Steps Involved in Sewer Relining?

There are a certain number of procedures that are taken care of while relining pipes to ensure that the leak is properly cured and the resin is activated properly. Following are some steps in the sewer relining process, 

  1. Check the damaged pipe to see if it is repairable or not – In some cases the damages to the pipe can be very severe in the form of a big crack or complete collapse of the underground pipeline system. In these cases, it is better to replace the entire piping system instead of relining. 
  1. Measure the pipe to locate the damage – Micro cameras are sent down through the pipeline which helps the experts measure the locations of the cracks and leaks accurately. This also helps them in modeling the sewer pipeline accurately, which will come in handy in later stages. 
  1. Clean the pipe for relining – The pipe is prepped for the lining and all the dirt and sediments are cleaned thoroughly. The cleaning is usually done using high-pressure water jets that force away all sediments. 
  1. Develop the pipelining and the bladder – After taking an accurate measurement of the damages, the lining is prepared and the section of the pipe is covered with resin from the inside. 
  1. Insert the liner into the pipe – The liner is then pushed into the damaged area and the bladder is inserted within the liner. The bladder is a balloon-like structure that is inflated so that the liner is pressed against that inner wall of the pipe. This cures the resin over time and the leak is cured. 


Sewer relining is a very effective way of repairing pipe leaks as it treats the problem without any need for digging or replacement. Relining Melbourne’s underground sewage system is easier than ever with relining techniques.
