What’s Trenchless Relining?

What is Trenchless Relining?

Trenchless relining repairs underground pipes with minimal excavation, by installing a new liner within the existing pipes, thus safeguarding your property.

Our expertise in trenchless pipe relining enables us to refurbish pipes across Sydney’s Jannali region without harming the environment.

The advantages of trenchless relining, compared to traditional pipe repair, encompass:

• Far less expensive
• Rapid completion
• Minimal surface disruption
• Enhanced pipe strength and durability
• Improved flow capacity
• Environmentally friendly

How Does Trenchless Pipe Relining Work?

The trenchless pipe relining process involves three main steps:

1. Inspection - We first inspect the damaged pipes using a remote camera. This allows us to assess the location, extent and nature of any cracks, breaks or blockages.
2. Cleaning - Next, we thoroughly clean out the pipes to prepare them for relining. This removes any built-up deposits or debris.
3. Liner Installation - Finally, we install the new pipe liner. This resin-impregnated liner is fed through the pipes and expands to form a tight fit. It is then cured using hot water, steam or UV light to harden it in place.

This process results in a revitalised pipe system with enhanced flow and durability, with minimal disruption.

Cleaning and Inspecting the Damaged Pipes

Using high-pressure water jets, we’ll remove any built-up deposits, roots, grease or other debris from inside the pipes. This ensures there are no obstructions that could impact the pipe liner installation, whether your pipe been previously damaged or not.

We use CCTV cameras for an in-depth review of pipe damage, revealing any cracks, blockages or other issues.

From the video, our trenchless technicians can identify all weak points and problem areas. We’ll pay special attention to sections prone to further deterioration, marking them for liner reinforcement.

By methodically cleaning and inspecting your pipes first, we set the stage for an optimally effective trenchless relining method. Understanding the full picture allows us to customise the solution for long-lasting results.

Installing the Resin-Impregnated Liner

Following cleaning and inspection, we proceed to install the resin-impregnated CIPP liner.

This liner consists of a flexible felt tube soaked in a thermosetting epoxy resin. It is wound onto a spool and fed through the damaged pipe from one access point.

As the liner is pulled into place, we use water pressure to ensure it tightly conforms to the interior walls. Air pressure can also assist expansion into pipe side connections.

We then harden the resin-coated liner using hot water, steam or UV light, resulting in a seamless, corrosion-resistant pipe.

Made from advanced composite materials, the sturdy CIPP liner can withstand high temperatures, pressure changes, chemical exposure, abrasion, and root intrusion.

Once cured, the liner becomes a durable barrier that guards against infiltration and further damage, restoring pipe functionality and flow capacity.

By precisely calibrating the liner dimensions to your pipes, we ensure optimal performance and durability from this trenchless solution.

Curing the New Pipe Lining

Once the resin-saturated liner is installed along the full length of pipe, the curing process begins. This critical phase transforms the flexible felt material into a hardened, watertight barrier.

We utilise advanced curing methods like hot water, steam or UV light exposure to activate the thermosetting resin. Heating the liner to temperatures around 80°C causes it to solidify. As the heat-induced chemical reaction takes place, the epoxy resin changes state, bonding all the felt layers into a uniform whole.

By monitoring temperature and cure times, our technicians fine-tune the process for the best results. The smooth, jointless pipe lining that forms serves as a protective corrosion and abrasion-resistant layer inside the damaged pipe.

The custom-fitted liner restores seamless functionality, leaving no weak points in the pipe. The cured liner resists chemical exposure, high temperatures, pressure changes and root intrusion far better than the old pipe ever could.

Our thorough curing process not only repairs but also strengthens your pipes, providing a long-lasting solution requiring minimal upkeep.

The Benefits of Trenchless Relining

Trenchless pipe relining offers numerous benefits over traditional excavation methods, delivering a swift, efficient, and less intrusive repair process.

Some of the key benefits of trenchless relining include:

• Cost Savings - Pipe relining reduces direct repair costs by 50-80% compared to full replacement. By avoiding extensive digging, it also prevents expensive landscaping or structural repairs.
• Faster Project Times - Relining is completed in one day rather than taking weeks. This minimises downtime and disruption for homes and businesses.
• Less Damage - No driveways, gardens or buildings need to be dug up. Trenchless repair is less hazardous, messy and destructive.
• Improved Flow - Smooth drain pipe interiors enhance drainage, water supply and gas flows compared to corroded pipes.
• Added Pipe Life - The durable CIPP liner adds another 50+ years of life expectancy compared to the previous pipe.
• Environmental Benefits - Relining avoids landfill waste while preserving trees and vegetation.

Given its numerous advantages, trenchless relining is increasingly the preferred method for modern pipe repair. Contact the team at Jannali Plumbing to learn more about how pipe relining can save you money, time and disruption.

When to Choose Trenchless Relining

Trenchless relining is ideal for underground pipes that would otherwise require costly and disruptive replacement. This includes pipes under:

• Concrete driveways, patios or foundations
• Mature trees and well-established gardens
• Pools, ponds and water features
• Footpaths, roads and busy areas

We generally recommend trenchless relining for:

• PVC, concrete or clay pipes 50mm - 300mm diameter
• Pipes with damage from cracks, breaks, root intrusion, or corrosion
• Sewer lines needing restoration without excavation risks
• Pipe connections underneath built structures

However, replacement may be necessary for severely damaged or completely blocked pipes. Our specialists can recommend the best and most economical approach.

Contact Jannali Plumbing to schedule an obligation-free inspection. We’ll assess if your damaged pipes are suitable candidates for trenchless relining in the Sydney region.

Signs You Need Trenchless Pipe Repairs

Deteriorating underground pipes can go unnoticed for years before serious issues arise. But waiting too long can cause extensive damage requiring full pipe replacement. Timely consideration of trenchless relining repairs can prevent further complications.

Common indicators that your pipes may require trenchless relining services include:

• Drain slow-downs or backups - If sinks and showers are draining slower than usual or pipes are clogging frequently, build-up deposits may be narrowing pipe diameters.
• Gurgling sounds from drains - These noises usually indicate partial blockages or venting problems that require attention.
• Musty or sewage smells coming from drains - Cracks in underground pipes can allow odours to enter your home. This also poses health risks from methane gas or sewerage contamination.
• Root intrusion - Nearby trees and shrubs often grow roots that invade cracks seeking moisture. Left unchecked, this causes major pipe damage.
• Cracked or uneven floors or walls - Foundation movement from soil erosion or pipe leaks under homes can lead to visible structural damage.
• Pools of water above or near pipes - This may signify leaks from joints or cracks that require sealing.

Catching early signs of drain pipe relining needs and addressing them through trenchless relining can restore functionality for a fraction of replacement costs. Contact Jannali Plumbing if you notice any of these common warning signs around your Sydney property’s drainage systems.
