Trenchless Pipe Relining: The Future of Drain Repair

Is trenchless pipe relining the right solution for you?

Nobody wants to deal with broken pipes, blocked drains, or sewer line failures. In the past, repairing pipes meant digging up driveways, gardens, and floors, leading to costly and time-consuming repairs. But trenchless pipe relining is changing the game.

Trenchless technology offers a non-invasive, cost-effective, and durable alternative to traditional pipe replacement. This method repairs damaged pipes from the inside, eliminating the need for major excavation.

So, is trenchless pipe relining the future of drain repair? Let’s explore its benefits, how it works, and whether it is the right solution for your plumbing issues.

What is Trenchless Pipe Relining?

Trenchless pipe relining is an advanced plumbing solution that repairs pipes without digging up your property. This method involves inserting a resin-coated liner into the damaged pipe, which is then cured in place to create a strong, seamless new pipe inside the old one.

How Does Trenchless Pipe Relining Work?

1. CCTV Pipe Inspection – A small camera is inserted into the pipe to assess the damage.
2. Pipe Cleaning – The pipe is cleared of debris, scale, and blockages using high-pressure water jetting.
3. Liner Installation – A flexible epoxy-resin liner is inserted into the pipe.
4. Curing Process – The liner is inflated and hardened using heat or UV light, creating a durable, corrosion-resistant lining.
5. Final Inspection – A second camera inspection ensures the repair is successful.

This process creates a new, seamless pipe inside the old one, extending the lifespan of your drainage system.

Advantages of Trenchless Pipe Relining

Trenchless pipe relining offers a cost-effective, and long-lasting solution for repairing damaged pipes without the need for extensive excavation.

1. Minimal Disruption to Your Property

Traditional pipe repairs require digging up driveways, gardens, and flooring, which can be costly and time-consuming to restore.

With trenchless technology, the process is non-invasive and requires only small access points, preserving your landscaping and property structure.

2. Faster Repair Time

Traditional pipe replacement can take days or even weeks, especially if excavation is required.

Trenchless pipe relining can be completed in as little as one day, reducing downtime and restoring your plumbing quickly.

3. Cost-Effective Solution

While the upfront cost of trenchless pipe relining may be slightly higher than traditional methods, it offers long-term savings by:

• Reducing labour costs (no need for excavation crews).
• Avoiding landscape and property restoration expenses.
• Minimising future maintenance needs due to its durability.

4. Enhanced Durability & Longevity

The epoxy resin lining used in trenchless pipe relining is highly resistant to:

• Corrosion
• Tree root intrusion
• Wear and tear from household waste and chemicals

With a lifespan of 50 years or more, trenchless relining provides a long-term plumbing solution.

5. Environmentally Friendly

Traditional repairs generate waste from old pipes and excavation debris. Trenchless pipe relining is an eco-friendly alternative because:

• It reuses the existing pipe instead of replacing it.
• It reduces soil and ecosystem disruption.
• The materials used, such as high-density polyethylene (HDPE), are recyclable.

Applications of Trenchless Pipe Relining

Trenchless pipe relining is suitable for various residential, commercial, and industrial settings, including:

1. Residential Homes

• Repairing cracked or leaking sewer pipes.
• Fixing blocked drains caused by tree root intrusion.
• Restoring old or corroded plumbing systems.

2. Commercial Properties

• Restaurants and hotels benefit from minimal disruption to operations.
• Office buildings with extensive underground piping avoid costly excavation.

3. Industrial Facilities

• Large factories with underground drainage systems can repair pipes without shutting down production.

This versatile solution can be used on PVC, cast iron, clay, and concrete pipes, making it suitable for various applications.

How Much Does Trenchless Pipe Relining Cost?

The cost of trenchless pipe relining depends on several factors, including:

• Pipe size and length – Larger pipes or longer sections will cost more.
• Severity of damage – Pipes with multiple cracks or severe blockages may require extra preparation.
• Accessibility – Hard-to-reach pipes may require additional equipment.

General Cost Estimates:

• Small residential pipe relining starts from $500 per metre.
• Larger commercial or industrial jobs can range between $3,000 to $15,000, depending on complexity.

Although trenchless relining has higher upfront costs, it saves money long-term by reducing labour, excavation, and property restoration expenses.
