What’s Trenchless Pipe Relining?

What is Trenchless Relining?

Trenchless relining rehabilitates damaged underground pipes without the need for excavation, preserving property integrity. Trenchless relining employs liners and resins to form new pipes inside existing ones, avoiding the need for invasive procedures.

This method involves inserting a flexible tube impregnated with epoxy resin into the damaged pipe, followed by curing with hot water or steam to harden the resin.

Trenchless relining offers advantages over traditional methods, being quicker, more economical, and better for the environment. It avoids property damage, minimises disruption, and provides sustainable relining options. The quick completion time also reduces exposure risks, such as during health concerns like pandemics.

How Trenchless Drain Relining Works

Here is an overview of our trenchless drain relining process:

1. Inspection - Initially, a camera is sent down the drain to assess pipe conditions and locate any damage. This CCTV drain inspection allows us to develop a custom relining plan.
2. Cleaning Subsequently, hydro jetting is employed to eliminate debris, rust, grease, and tree roots, ensuring clear flow.
3. Resin Selection The best relining materials are chosen, typically epoxy or polyester felt resin liners, suited to your pipe’s size, composition, and damage level.
4. Installation The liner, infused with water-activated resin, is then inserted and cured using hot water or steam, bonding it securely to the pipe.
5. Inspection A final CCTV inspection confirms the absence of defects in the lined pipe, with the refurbished drain ready for use within hours.

Unlike traditional pipe replacements requiring extensive digging, Our The trenchless relining method is efficient, non-intrusive, and environmentally considerate. Your property remains undisturbed as we restore your drains from within, with no digging up of landscapes required.

CCTV Pipe Inspection

Video pipe inspection using CCTV is an essential initial step in the trenchless relining process. We thread a specially designed waterproof camera through your drain line to visually assess the pipe condition and pinpoint any damaged sections or blockages.

The camera sends real-time images and video back to our trenchless experts as it travels through the pipe. We carefully analyse the footage, noting issues like cracks, fractures, root intrusion, corrosion damage, offset joints, etc. We can even identify exactly where leaks or blockages are originating from within the pipe system.

CCTV technology allows us to map out the full extent of damage and develop a strategic trenchless relining plan tailored to your pipes. It eliminates the ‘guesswork’ involved and ensures optimum results from our non-invasive pipe repair solutions.

The foremost advantages of this diagnostic camera inspection are:

• Precise pipe damage identification
• Exact mapping of affected areas
• Preemptive spotting of pipe integrity issues
• Ability to assess flow efficiencies
• Customised repair plans for guaranteed results

So before we commence the relining, it’s vital we understand what’s occurring within your pipe network from the inside-out. Our CCTV pipe inspection technology enables minimally invasive, efficient and successful trenchless repairs for your home or business.

Cleaning and Preparing the Pipe

Before installing the trenchless liner, we thoroughly clean out the damaged pipe to ensure proper adhesion. Any debris, rust, grease or roots present can affect bonding of the epoxy resin liner.

Our specialists employ advanced hydro jetting technology, with water pressures reaching 5000 PSI to clean the pipe interiors. High-pressure water jets scour off old pipe buildup, enabling optimum liner contact.

Specialised augers may be utilised to remove obstructive tree roots or vegetation. The final step is a complete CCTV inspection confirming no obstructions remain before we saturate the liner with resin.

Proper pre-installation cleaning ensures the drain system is optimally prepared for successful trenchless relining. Thorough pipe scouring allows the flexible epoxy liner to bond tightly to the walls, providing a seamless pipes-within-pipe solution.

Installing the New Pipe Liner

Once the damaged pipe is fully cleaned and prepared, we begin the process of pipe lining without the need for excavation by saturating the trenchless liner with our special epoxy resin. The liner material is a flexible felt tube made of polyester or epoxy that can easily navigate bends.

Our technicians thoroughly saturate the liner and then use air pressure to invert it into the pipe. An inversion drum feeds the flexible liner through the pipe continuously until it extends beyond the damaged section.

We circulate hot water or steam throughout the liner to activate the resin and stimulate curing. This finalises the pipe repair, with the flexible felt solidifying and molding snugly to the existing pipe walls. The curing process completes in 2-3 hours, resulting in a sturdy, seamless and corrosion-resistant pipe.

This delivers renewed structural integrity and flow capacity with no disturbance to the surface. Our epoxy liners, with a design life exceeding 50 years, outlast traditional iron or clay pipes. Our drain pipe relining utilises advanced technology to facilitate significant repairs with little to no interruption.

Final CCTV Inspection

Once the new trenchless liner is installed, we perform one final CCTV drain inspection. This allows us to thoroughly check the liner for correct placement and smooth transitions at connection points.

Our camera carefully examines the refurbished pipe to confirm:

• No defects, cracks or gaps in the liner
• Liner is bonded evenly and tightly to the old pipe walls
• All affected sections have been lined without gaps
• Flow is unobstructed throughout newly lined pipe

This quality assurance process ensures our non-invasive drain repair has restored functionality for the long haul. You gain peace of mind knowing your underground pipes have a renewed 50+ year lifetime thanks to our precision CCTV-guided trenchless relining.

Benefits of Trenchless Relining

Compared to traditional excavation methods, trenchless relining offers numerous advantages:

• Cost Savings - Pipe relining reduces expenses by 50% or more since no excavation or repaving is needed.

Our liners are made from polyester or epoxy resin-infused felt tubes. Once installed and cured, they create a seamless, leak-proof, and corrosion-resistant pipe interior.

• Our epoxy resins offer unmatched durability, able to withstand decades of pipe flow, ground stresses and chemical exposure.
• The flexible polyester felt liners conform to any pipe shape for seamless repairs.
• Impervious to roots, rodents, salts, acids, gases, and effluent, CIPP materials guarantee over 50 years of reliable service.

You can rely on our carefully chosen CIPP products to enhance and rejuvenate your drainage system. Trenchless relining gives old pipes a new, long-lasting lease on life.

Evaluating Your Relining Options

When assessing trenchless drain relining for your property, consider the following factors:

• Pipe Condition - What is the extent of damage? Can lines still effectively drain during the process? A CCTV inspection provides insight.
• Pipe Material - Clay, concrete, PVC, cast iron? Knowing your existing infrastructure helps determine best repair practises.
• Pipe Size & Length - Available liner dimensions differ. We assess if lining can practically restore functionality given pipe diameters and total length.
• Process Impacts - Consider how long repairs might affect your home or business. We communicate timelines clearly upfront.
• Cost Savings - Lining reduces expenses 50%+ over full pipe replacement. We offer detailed quotes outlining project expenses.
• Future Benefits - Long-standing durability and improved drainage extend pipe functionality for many years, with new epoxy barriers shielding against future root intrusion.

By evaluating these key criteria, our trenchless specialists recommend the optimal relining materials, process and timeline to suit your drainage system needs with minimal disruption to property or routine.
