It is great to have trees around your property, but it is important to be aware that tree and plant roots post a great danger to your sewage system. Tree roots can grow three times the tree’s height and in the search for a water source, they may end up intruding sewage pipes. When you notice gurgling or bubbling sounds, a foul smell when you use the toilet, overflowing sewage water in the sewage gully and rising toilet water then you are sure to have sewage pipe intrusion.
More than three decades ago, the only options for pipe repair methods were traditional methods like pipe replacement. These processes often involved excavation of broken pipes and replacing them with new ones. This practice translated to disruption of properties, especially with regard to broken pipes that ran underneath the house. Today, there is another more practical option known as ‘pipe relining’.
What is pipe relining?
In the past thirty years, pipe relining has been introduced to Australian households. This is a trenchless pipe repair method that involves putting a protective inner lining into the broken or cracked pipes instead of replacing them. This can be done for pipes ranging from 40mm to 600mm in length. The liner can be stretched up to 40-50 metres.
Eric Wood, in 1971, implemented the first cured-in-place pipe (CIPP) technology. This was called “Instituform’ which was derived from the Latin term meaning, ‘form in place’. This became the generic name for the CIPP process for several years.
How is pipe relining performed?
Pipe relining entails the following steps which we meticulously execute:
Initial pipe cleaning. The first step is to partially clean the sewage pipes using a high pressure water jetter. This facilitates the video inspection.
CCTV inspection. A video inspection is conducted next to assess the extent of the cracks or damages in the sewer pipes. This process is also essential in determining whether pipe relining is suitable for your problem.
Second pipe cleaning. Once you agree to proceed with pipe relining, thorough cleaning will be done again to the pipes to facilitate the insertion of the pipe liner.
Pipe lining insertion. The pipe liner made of fibreglass or cloth is inserted into the pipe. It can be stretched for up to 50 metres. The pipe liner is expanded using an inflating device so the resin will firmly attach the new pipe liner inside the old pipe.
Curing the pipe liner. The resin is cured for some time (usually a few hours) so that the new pipe will settle and bond with the new system. Steam is used to aid the curing process.
Final CCTV inspection. Another video inspection is performed to ensure that the resin is properly cured and there are no defects.
