30 Jan The Anatomy of Sewer Pipe Relining: Understanding How No-Dig Works

Blocked drains, foul smells, and pooling water are problems most homeowners on the North Shore have faced at some stage. Traditionally, this would mean excavation that takes out everything in its path: trees, gardens, driveways, and more. But what if we told you there was another way? Introducing trenchless sewer pipe relining North Shore technology, which is changing the game for Aussie plumbing companies by allowing no-dig sewer relining technicians to access damaged pipes underground, with no digging required.

We explain everything you need to know about the science behind sewer pipe relining below. If you’re still wondering whether sewer pipe relining North Shore is right for your property, read on to discover how Australian-made and internationally recognised no-dig technology can repair your underground pipes from the inside out.

What Happens Underground: The North Shore Sewer Pipe Relining Process, Start to Finish

The first step in any drain pipe relining process is gaining a clear understanding of the problem at hand. Using state-of-the-art CCTV drain cameras, our sewer relining technicians will access your underground pipes through an existing access point and insert a miniature camera into the branch lines. Through close inspection of the high-definition video footage, our technician and you can assess the condition of your pipes and identify the root cause of your problem. Whether the damage is caused by invasive tree roots, soil movement, corrosion, or general wear and tear over time, we can help. After the initial CCTV drain survey, our technician will discuss your options with you and advise whether sewer pipe relining North Shore is the right course of action.

If sewer pipe relining North Shore is your chosen repair method, we’ll begin the preparation process by flushing your pipes with high-pressure water jets. This process removes leaves, existing tree roots, fat, oil, grease, and any other unwanted debris from the walls of your pipes. It is vital that we clean your pipes before relining them, as the epoxy liner we insert into your damaged pipe needs to bond to the existing structure with no barrier. Next, our technicians will measure the affected pipe and cut a suitable textile liner. Liners are commonly made from either felt or fibreglass and are completely waterproof when saturated with an epoxy resin mixture. (In Australia, epoxy products must meet specific requirements to be used for this purpose.)

The epoxy-infused liner is then placed inside the damaged pipe using what is known as an inversion drum. Using air or water pressure, we force the liner into your pipe in an inverted position. As the liner unfolds along the pipe, it begins to adhere to the interior walls of the damaged section. Because it is made from a flexible material, the liner can mould to the internal shape of the pipe, including bends of up to 90 degrees. The resin covers holes and cracks in the pipe to help ensure none are missed. Once cured, you effectively have a new pipe: a pipe within a pipe. Epoxy resin can take anywhere from 3 to 8 hours to cure. During this time, we recommend avoiding the use of mains water. Once set, the liner becomes hard and strong.

If you’re wondering, “How much does sewer pipe relining cost?”, look no further. Unlike excavation, where labour is only one aspect of restoring a damaged pipe, relining can provide excellent value for money. The average sewer pipe relining cost Sydney homeowners should expect to pay ranges from $400 to $800 per metre. Considering you’re not paying to dig up your property and cover associated landscaping or driveway repairs, not to mention weeks of inconvenience, we think that’s pretty reasonable. Most sewer pipe relining can be completed in less than 8 hours, resulting in minimal disruption to your business or home life.
