What is Trenchless Pipe Relining?

An Introduction to Trenchless Pipe Relining

Trenchless pipe relining efficiently repairs underground pipes without the extensive excavation traditional methods require. This relining technique uses a resin-impregnated tube, inserted and inflated inside the existing pipe, forming a sturdy pipe within a pipe.

At Guildford Plumbing, we specialise in trenchless drain and sewer relining for residential and commercial clients throughout Guildford and the greater Sydney area. With over 10 years of expertise in the latest no-dig drain pipe renovation, we are trusted leaders in delivering pipe solutions that are long-lasting, cost-effective and environmentally friendly.

Trenchless relining surpasses traditional pipe replacement with its effective interior pipe restoration. The seamless epoxy barrier stops leaks, prevents root intrusion and corrosion damage, eliminates infiltration from soil and tree roots, and greatly extends the life of ageing or deteriorated pipes.

How Trenchless Relining Works

The trenchless relining process comprises these steps:

1. First, we use CCTV cameras to thoroughly assess the interior condition of your pipes and locate any defects, damage or blockages.
2. Next, we clean and prepare the interior pipe surface so it’s ready for the new liner.
3. A resin-saturated liner material made of flexible polyester or epoxy is then fed through an existing cleanout or access point and guided through your pipes.
4. We inflate the liner with water pressure so it fits snugly against the pipe walls.
5. Finally, we circulate hot water or steam to rapidly cure and harden the liner into place. The liner bonds securely to the old pipe, providing a smooth, jointless and corrosion-resistant new pipe wall.

Trenchless lining’s key advantage is that it can be completed without digging, avoiding property damage. Using current access points, we reline pipes with minimal surface impact.

The curing process chemically hardens the liner using hot water and steam, so there are no glues, solvents or chemicals introduced into the piping system. Our Guildford plumbing specialists professionally oversee the entire no-dig relining operation.

Materials and Processes Used

Trenchless relining employs engineered materials that repair drains without digging, enduring years of underground use. The most common include:

• PVC (polyvinyl chloride) - A durable, long-lasting plastic perfect for potable water pipes. It resists corrosion and abrasion.
• EPDM (ethylene propylene diene monomer) - An extremely flexible synthetic rubber ideal for bends and joints. It is oil and weather-resistant.
• Polyester or epoxy resins - Either is combined with felt/fibre to form the impregnated liner that cures to form a smooth, jointless pipe. Excellent chemical resistance.

Utilising CCTV data, we measure pipes for a tailored liner. We then cut and shape the liner material as needed. Using an inversion process, we saturate the liner with water-activated resin before pulling it through existing access points into your pipe.

Once in position, we circulate hot water or steam to cure the resin. Temperatures around 71°C are typically employed for a complete cure.

This causes the resin to harden, bonding the liner firmly to your old pipe walls. This yields a seamless, long-lasting 'pipe within a pipe’.

When to Choose Pipe Relining vs Replacement

Pipe relining is usually preferred over replacement in situations where:

• The existing pipes are still structurally sound but have issues like roots, corrosion damage, cracks or leaks.
• You wish to avoid extensive property damage/landscaping work that pipe replacement requires.
• Pipe access is difficult due to structures, driveways or landscaping located under them.
• You need a faster solution without having to worry about disrupting household or business activities.
• Cost is a concern - relining saves on labour and other pipe replacement expenses.

If more than half of a drain pipe is severely damaged, as revealed by CCTV inspection, relining often provides a more durable solution. Consider both the costs and benefits between methods.

At Guildford Plumbing, we offer free consultations to assess your pipes, advise on the best solution and provide accurate quotes so you can make an informed decision. Trenchless relining restores your pipes internally, without digging, ensuring minimal disruption and excellent long-term value.

Limitations and Considerations of Trenchless Relining

Although trenchless relining is highly efficient in repairing deteriorated pipes, there are a few limitations and factors to consider:

• If a pipe is severely damaged, misaligned or collapsed, replacement may still be required as relining works best on pipes in reasonable structural condition.
• Roots and heavy buildup may need to be cleared for the liner to adhere correctly, which is part of our comprehensive pipe patching services. We use high-pressure water jetting and mechanical cutters as needed.
• Over time, some infiltration between the old pipe and liner may occur requiring occasional maintenance. But the liner extends pipe life considerably.
• Proper installation requires aligned cleanouts and pipes free of sharp bends or significant reductions.
• While disruption is minimal, water supply may be interrupted for several hours during the relining process until cured.

Our experts can determine if your pipes are ideal for trenchless relining, a method aimed at minimal disruption. We also manage any limitations using tailored pipe preparation and precision installation methods honed from years of expertise.

Cost Comparisons to Traditional Pipe Replacement

Trenchless relining offers considerable cost savings over traditional excavation and pipe replacement. Choosing relining, Guildford Plumbing customers typically save 40-50% on project costs.

Here is a breakdown of typical project cost differences:

• Labour - Relining uses less labour onsite to get the job done with no trenching required.
• Materials - Liner materials cost 20-30% less than fully replacing aged pipes.
• Time - The 1-3 day relining process is far quicker than replacing pipes over days or weeks.
• Restoration - No expenses are incurred to repair lawns, pathways, driveways or landscaping.

The long-term financial benefits are evident, with new epoxy or PVC liners offering 50+ year lifespans and minimal upkeep. Over the lifetime of your pipes, trenchless relining gives you the highest return on investment.
