02 Mar Trenchless Pipe Relining FAQs

Trenchless pipe relining is becoming a common method used to repair broken, leaking, and blocked drains and sewer lines for Sydney homes and businesses. The quick, efficient, and affordable nature of pipe relining has made it the preferred choice over traditional pipe repairs such as pipe replacement. As the name suggests, trenchless pipe relining does not involve digging or excavation. The efficiency and results of pipe relining is proven to be the same, if not, better than pipe replacement. 

How does trenchless sewer and drain relining involve?

Plumbing relining specialists first conduct CCTV pipe inspection to determine the location of leaks, seepage, root intrusion, cracks, and other damages. Through CCTV pipe inspection, plumbing specialists are able to identify the extent of damage in the pipe, allowing them to create a repair plan that delivers the best outcome.

In case pipe relining is the chosen method of repair, the pipe is first cleaned using a hydro-jet system that injects high pressure water into the sewer or drain pipeline. This is done to remove wastes, oils, grease, and other materials that may disrupt the relining procedure. It is important for the walls to be kept clean and free from residue to ensure the relining material will adhere properly. 

• The relining material is then assembled for application. The liner is placed into a calibration equipment typically made from fibreglass or polyester material essentially pushes the line out along the walls of sewer and drain lines. 
• Epoxy resin is properly mixed to ensure that it cures and forms the new lining properly. An inversion trailer is used to compress the line and to ensure that the epoxy resin reaches all the fibres. 
• Once the liner is loaded into the inversion tank, the relining process begins. The pipe is then filled with the epoxy resin through an upstream access point. 
• Once all the resin is loaded, the curing process then begins. Curing is important as this involves the hardening of the resin material. The resin is left to air-dry, while some use hot water or steam to expedite the curing process. 
• Finally, ultraviolet light is used to finish up curing the epoxy resin.
• Once the resin is completely dried and hardened, a cutter is used to open junctions that were closed when the resin was forced into the pipe. 
• A final check is made to ensure relining is properly done without any wrinkling or open spaces in the epoxy resin material. 

How long does pipe relining last?

Trenchless pipe relining is proven to be extremely durable for any sewer or drain pipe material. Typically, resin material lasts for more than a decade. Depending on the quality of the epoxy mix, some companies offer between 10 and 50-year warranty on their pipe relining service in Sydney.

What are the benefits of trenchless sewer relining? 

• Easy to implement

Plumbing relining contractors are equipped with proper equipment and tools for relining. As described earlier, the pipe relining process is easy and straightforward. However, only professional plumbers can implement pipe relining, as they are trained to properly conduct the procedure. 

• Fast curing time 

Homeowners and commercial property owners don’t have to wait for weeks to have their sewer and drain pipes repaired. Depending on the severity of the damage, pipe relining only takes a few days to a few weeks to be completed. 

• Cheaper than pipe replacement

Plumbing companies that offer sewer pipe relining dispatch a few plumbers to conduct the procedure. Since there is no digging or excavation involved, customers enjoy significant savings due to reduced labour costs. 

• Less mess

No excavation or digging means there will be less mess to deal with after repairs. Most often plumbing companies clean after themselves once the pipe relining procedure is finally completed. 

• Materials are durable and long lasting

The resin material used in relining drain and sewer pipes are made from durable compounds that ensure its long-lasting functionality. Relined pipes are less likely to suffer from cracks and damages, hence they are a better investment than traditional pipe replacement. 

• Minimal to no interruption to your daily routine

You don’t have to worry about your landscape or pathway to be destroyed during a pipe relining service. Since there is minimal digging, you can still resume your normal routine, with only a few hours of disruptions at most. You also avoid costly repair of your landscape or driveway- common issues that are associated with pipe replacement procedures. 

• Partial sewer pipe relining

If the damage is only limited to a small portion of the pipe, partial relining is recommended. This means less disruption and cheaper price rates but with the same superior results.
