Introduction to Pipe Relining

Pipe relining is a modern, efficient approach to repairing damaged pipes without the need for traditional excavation methods. It involves inserting a resin-saturated liner into the existing pipe, which is then cured to form a smooth, seamless new pipe within the old one.

Paddington Plumbing is a leading provider of pipe relining services in the Paddington area of Sydney. We understand that speed and minimal disruption is often the priority when pipes become damaged or corroded.

Pipe relining allows us to restore your pipes quickly with just two small access points cut into the pipe, avoiding the need to dig trenches through walls or floors.

The whole pipe relining process can usually be completed in just one day. We use state-of-the-art CCTV pipe inspection equipment to assess the scope of damage and determine if your pipes are suitable for relining. If so, we can then immediately get to work restoring your pipes from the inside-out. This avoids the major structural work and renovations often required with traditional pipe replacement.

Relined pipes can have a lifespan of 50 years or longer if correctly installed. We back our work with long-term guarantees so you can have peace of mind that your plumbing has been given an extensive new lease of life.

Assessing Pipe Damage with CCTV Inspections

Before beginning any pipe relining work, we need to carry out a detailed CCTV pipe inspection. This involves feeding a high-resolution camera through your pipe system to assess the precise scope and location of any damage or corrosion.

CCTV inspections allow our technicians to evaluate the condition of difficult-to-access pipes without needing to excavate or cause major property damage. The camera transmits real-time images to our team, clearly highlighting any cracks, leaks, blockages or collapsed sections requiring repair.

Vital information such as pipe length, material and diameter is also collected during the CCTV process. This data allows us to determine if your pipes are suitable candidates for relining based on the severity and nature of the damage. It also informs the tailored approach we take to refurbishing your pipes.

CCTV pipe inspection is a key enabling technology in speeding up the pipe relining process. Within just 30-60 minutes we can thoroughly assess all problem areas rather than spending days exploratorily digging to locate issues. We can then immediately proceed with targeted relining in the required sections.

Preparing Pipes for Relining

Before we can install the new pipe liner, the existing pipes need to be thoroughly cleaned and prepared to ensure proper bonding. Any debris, rust, or buildup inside the pipes can prevent the liner resin from properly adhering.

We use specialised high-pressure water jetting to scour the interior pipe walls. This clears away any substances that could reduce adhesion while also smoothing the surface to create better friction and grip for the liner.

Small access points are then cut into the pipe at intervals. These entry points allow us to thoroughly clean the entire pipe length while also granting access for installing the liner.

With the pipes cleaned, we then use an epoxy primer coating specifically designed to facilitate ideal bonding between the old pipe and new liner. By taking the time to correctly prepare pipes ahead of relining, we can complete installation rapidly and reliably. Proper prep work ultimately speeds up the entire restoration process.

Once preparation is complete, we immediately begin saturating the resin-coated liner material and inserting it through the pipe access points. The epoxy aids curing and produces a long-lasting seamless join. If you need relining services, contact us today to schedule an inspection and quotation.

Pipe Relining Methods

There are two primary methods we use for pipe relining at Paddington Plumbing depending on the specifics of your pipe layout and damage.

Inversion Pipe Relining

The inversion process involves saturating a resin-coated liner material and invert (flip inside out) it through the pipe. Compressed air pressure causes the liner to bond tightly to the interior walls as the resin cures.

This seamless lining method works very well for long straight pipe sections in runs between two access points. As curing takes just a few hours, an entire pipe length can be relined in a single rapid process.

Robotic Cutter Relining

For pipe systems with multiple junctions and bends, we make use of robotic relining. The felt liner is pulled through the pipe manually, allowing it to navigate twists and turns.

A special cutter robot is then sent through which trim fits the liner perfectly to the pipe walls. The resin infusing and curing process bonds it in place. Robotic precision aligns with inversion relining speed making it ideal for complex pipe layouts.

Curing the Liner

Once the pipe liner is installed, we use specialised techniques to rapidly cure and harden the resin, completing the relining process. The curing method used depends on the liner type and pipe layout specifics.

For inversion liners, we often rely on ambient air curing. The resin used is specially formulated to harden at room temperature by exposure to air. Supplying compressed air throughout the pipe accelerates this curing, allowing the liner to fully harden within just a few hours.

Alternatively, hot water or steam can be pumped through the pipes to heat the liner, significantly speeding up resin curing times. Temperatures are carefully monitored to avoid over-curing.

Certain flexible liner types featuring integrated ultraviolet-sensitive resin can be cured rapidly using UV lamps. As the light travels down the pipe, the resin hardens in seconds behind it.

By using the fastest curing method viable for each unique job, we can restore a failing pipe system with a seamless structural liner in just a single day. Proactive pipe maintenance and timely pipe repair prevent future issues, so call us if you suspect your pipes need assessment or relining.

Completing the Pipe Relining Process

Once our relining technicians determine the resin is fully cured, the pipe relining process moves into its final quality assurance stages.

We thoroughly flush the pipes to remove any residual debris before sending a camera back through for a final post-installation CCTV inspection. The resulting images are reviewed to ensure the liner has smoothed over cracks and damage points as intended without any defects.

If needed, we can also perform water tightness testing by pressurising the pipe and monitoring it for leaks. This confirms the relining has restored the damaged sections to a structurally sound state.

Provided we are fully satisfied with the liner installation, all that remains is to carefully remove the temporary access points cut into the pipe and make good the surface. Your pipes now have an expertly installed 50+ year liner ready to reliably serve your plumbing needs.

The entirety of this pipe relining process takes just a single day in most situations. We strive to minimise disruption while providing high quality, long-lasting pipe repairs. Contact Paddington Plumbing to schedule an inspection or quotation today.

Benefits of Pipe Relining

Pipe relining provides numerous advantages over traditional pipe replacement methods. The key benefits include:

Saves Time

The entire relining process often takes just a single day. Avoiding large-scale demolition or renovation work means your water service and plumbing can be restored rapidly.

Minimally Invasive

Only small access points are cut rather than digging huge trenches. This results in much less property damage and disruption inside your home or business.

Long Lasting

Correctly installed pipe liners have an expected service life spanning 50 years or longer. This extensive lifespan exceeds that of traditional pipe materials.

Cost Effective

By restoring pipes rather than replacing them, relining provides major cost savings. The localised process scale keeps labour times and material costs low.

Structurally Reinforced

The seamless epoxy liner essentially creates a “pipe within a pipe” adding a protective layer inside ageing pipes prone to corrosion and cracks over time.

Maintaining Relined Pipes

Properly maintained relined pipes can easily achieve or exceed their 50-year expected lifespan. There are simple steps homeowners can follow to get the most out of a pipe relining investment:

Regular Flushing

It’s good practise to regularly flush all plumbing with clean water to prevent mineral deposits or debris buildup inside pipes. We recommend flushing relined pipes once every 1-2 years.

Avoid Chemical Cleaners

Harsh chemical drain cleaners and pipe decloggers should generally be avoided with relined pipes as they can damage the inner liner over time.

Address Minor Issues

If you experience the occasional drain blockage, slow drain or gurgling pipes, have them professionally inspected and cleared right away. Minor issues left unchecked can lead to larger problems down the track.

Watch For Leaks

Keep an eye out for any water spotting or damp areas on walls/ceilings which may indicate underground pipe leaks. Leaking pipes are more prone to damage and corrosion.

By proactively maintaining your relined plumbing and having any minor faults rectified promptly, you can reliably extend the longevity of the pipe restoration work. Contact Paddington Plumbing for professional drain inspections and maintenance.
