Relining Repairs Pipes in High-Traffic Areas

Introduction to Pipe Relining in High-Traffic Areas

In busy urban locations such as Penrith, Sydney, traditional pipe repair methods involving significant excavation can disrupt daily life. Our trenchless pipe relining mitigates the impact on your home and daily activities.

Sewer pipe relining rejuvenates your drainage system by forming a durable new pipe inside the old one using a flexible epoxy resin. The hardened epoxy resin seals cracks and leaks, restoring structural integrity while preserving traffic flow and landscaping without intrusion.

What is Pipe Relining and How Does it Work?

Drain relining is a trenchless technique that rehabilitates compromised pipes by forming a new conduit within the existing structure, without the need for digging. The process effectively resolves drainage issues as follows:

1. First, our dedicated team utilises state-of-the-art CCTV cameras to meticulously inspect your pipes, revealing any anomalies such as cracks, leaks, or blockages.
2. Next, we clean and prepare the pipes so they are ready for the epoxy resin liner to be inserted.
3. A supple, resin-saturated liner is pulled through, or inverted, into the pipe which is treated, thoroughly coating the inner surface and sealing off any imperfections.
4. Under UV light or high pressure steam, the liner material solidifies to form a smooth, seamless and extraordinarily robust new lining inside your existing pipe.
5. Once set, the epoxy liner is often stronger than the original pipe, resisting tree roots, corrosion, abrasion, and blockages, assuring longevity.
6. Because there’s no digging up your garden, pipe relining has minimal impact on the surrounding infrastructure or environment.

Pipe relining is versatile, compatible with various piping materials such as concrete, PVC, cast iron, and clay. This method addresses issues in pipes from 50 to 900 mm in diameter, ensuring they function optimally.

CCTV Inspection to Assess Pipes

It’s essential to assess the existing condition of your sewer before commencing any pipe relining project, and you can contact our specialist team for further advice. You may contact our team for assistance with special CCTV drain cameras to achieve precise results.

Our pipe relining experts will insert a high-resolution camera into your pipe via an access point like a manhole or gully trap. As the camera traverses into your pipes, it transmits live video footage to our team, who can help identify any issues throughout the entire system.

From this CCTV inspection, we can help to pinpoint the exact locations of any issues within your underground pipes, identifying cracks and leaks, and blockages caused by roots or buildup. We’ll also pinpoint potential trouble spots, offering solutions for problems that might require future attention.

Equipped with this precise diagnosis, We can customise the pipe relining solutions your pipes require, ensuring that our strategies integrate seamlessly. We know exactly which sections require a pipe reline, using bespoke solutions that include specialty resins or reinforcement materials. This precision ensures outstanding results in restoring the integrity of the pipe system.

So while not a glamorous part of the process, a CCTV drainage inspection is essential, especially when there’s a need to examine sewer conditions. It guides informed decision making so we can deliver repairs for a broken pipe that stands the test of time.

Modern No-Dig Pipe Relining Methods

Unlike traditional methods that need to dig up your property, Our range of trenchless pipe relining services is unobtrusive, indicating a smarter approach to pipe repairs. As pipe relining specialists, some of the leading no-dig methods we use include:

Inversion Lining

This innovative trenchless pipe relining method inverts a flexible epoxy resin liner into the damaged, deteriorated pipe sections of your plumbing via access points. Heat or steam pressure cures the liner material, a fix for the problem, to form a durable new pipe wall bonded to the inside old pipe.

Pull-In-Place

A reinforced felt liner soaked in epoxy resin is pulled into pipes, addressing the damaged and deteriorated sections and inflated to form a tight fit. Once cured, it restores structural integrity.

Spiral Wound Liners

For large pipes over 760 mm in diameter, we install spirally wound PVC strips to form a pipe liner. An epoxy coating creates a smooth, protective barrier.

So while traditional replacement digs up surrounding areas, modern relining methods offer faster, neater and longer-lasting pipe repairs with no excavation required.

Process of Relining Pipes Explained

Opting for pipe relining over new installation avoids the hassles linked to traditional pipe replacement. Here is a step-by-step overview:

1. Initial CCTV Inspection: We thoroughly inspect the inside of your pipes using a camera to identify any issues.
2. Pipe Cleaning & Prep: We clean out any debris or obstacles from the existing pipes, then prepare surfaces so the liner will properly adhere.
3. Insertion of Liner: A flexible, resin-coated liner is inverted or pulled through the full length of pipe.
4. Curing & Hardening: The liner is cured using hot water, steam or UV light to harden into a smooth, tough pipe.
5. Final CCTV Review: We perform one final camera inspection to ensure perfect results.

Our pipe relining service is efficient and clean, bypassing any need for excavation from start to finish. It keeps driveways, landscaping and traffic flowing without disruption. The new epoxy barrier surpasses the strength of the original pipe, promising durable repairs for decades to come.

Inversion Lining vs Pull-in-Place Relining

There are two main methods our expert plumbers use to reline pipes - inversion lining and pull-in-place relining. Each has its own advantages:

This method inserts a flexible, epoxy resin-coated liner into the damaged sections all around your plumbing through an access point. Steam pressure or hot water then inverts the liner, providing a relining solution that coats the inner walls. Once cured inside the old structure, it forms a smooth, seamless new water pipe integrated into existing systems.

Inversion lining works well for long pipe runs from 4 up to 36 inches in diameter. It enables pipes of any shape to be efficiently relined.

Pull-in-Place Relining

Here, a felt liner soaked in epoxy resin is pulled through the full length of the pipe, completing the pipe lining process manually. It is then inflated so it presses firmly against walls to repair defects. When set, it restores strength.

Pull-in-place techniques can repair pipes, drains of 2 inches or larger. It offers precision for short or curved pipe sections. But pipeline access at both ends is needed.

The precise method can be determined for your pipes, contingent on factors like size, length, bends, and site access. Our experts assess conditions first before commencing your pipe relining with minimal fuss using either method.

Longevity and Durability of Relined Pipes

One of the biggest advantages of pipe lining over traditional pipe repair is the exceptional durability and longevity of the relined system. The flexible epoxy resins used in the relining process can withstand decades of usage, ensuring the condition pipes remain intact with ease.

Once set, The robust epoxy liner, a byproduct of the sewer line relining process, is a pipe relining solution notably stronger than the original sewer pipe. It forms a hard, protective barrier that shields against further deterioration. This barrier is seamless with no joints or gaps where new leaks could emerge.

Your relined pipes hold up exceptionally well over time. They are:

• Resistant to abrasion from soil, roots or flowing effluent
• Impervious to acids and chemicals in waste water
• Able to flex and withstand ground movement or tree roots without cracking
• Free of gaps where roots can enter or leaks can emerge

With such reliable relining solutions, you can depend on the durability and performance of your pipes for decades. There’s no need for further repairs as the epoxy liner remains protective against corrosion and harsh weather conditions. Therefore, relining offers a permanent solution to your plumbing needs, ensuring long-term durability with little to no upkeep.

Pipe Relining vs Traditional Repair: Cost and Process Comparison

When it comes to repairing damaged pipes, pipe relining offers a clear advantage over traditional replacement methods. Here’s a comparison of the key differences:

Costs

To install new pipes, traditional methods require extensive excavation to access and remove the old ones, then to install the new ones. The labour and machinery involved in these processes can make you wonder about the cost pipe relining bears, often amounting to $300 per linear metre or more. There are also costs to repair surrounding driveways, paths and landscaping.

In contrast, the cost of pipe relining solutions can save on digging and is significantly more affordable, potentially offering substantial savings. With no potential to damage your property’s surroundings, considering the long-term benefits, the cost of pipe relining represents a more economical choice.

Process & Disruption

Traditional pipe replacement is disruptive, with machinery tearing up driveways and yards and causing street closures. When there’s no need to dig, the process usually takes merely 1-2 weeks.

Pipe relining technology enables seamless liner insertion into existing pipes, usually completed within hours with minimal disruption. It takes just 1-3 days with no noise, property damage or inconvenience. Traffic and property access are unaffected.

Structural Integrity

While traditional pipe replacement seems advantageous, joins between sections leave weaknesses for future leaks and root infiltration. Relined pipes are seamless and joints don’t degrade over time.

The epoxy barrier formed is stronger and more durable than the original pipe material. It resists chemical corrosion and abrasion for decades. Consulting with a pipe relining specialist shows the superior durability of this method compared to traditional repairs.

To get pipe relining as a quicker, tidier, and more cost-effective pipe repair option, Our advanced techniques provide a superior repair option for plumbing issues over traditional replacement.

When is Pipe Replacement Necessary Over Relining?

While pipe relining is usually non-disruptive, some cases necessitate full pipe replacement.

For severely damaged or fully blocked pipes beyond repair, pipe replacement might be necessary, necessitating more intensive solutions. Relining also has limitations based on pipe size and configuration. Replacement is generally recommended for complex networks or main sewer lines exceeding 900 mm in diameter.

In scenarios where you need sewer pipe attention, such as older pipes with severe rust, they may be too deteriorated to reline. Clay pipes that have collapsed or shifted allow too much groundwater infiltration for relining.

During our initial CCTV pipe inspection, we thoroughly assess the existing system. We check pipe construction, condition, diameter, routing and material used. From our comprehensive analysis, the professionals at relining companies like ours can advise on whether relining or full replacement is the most beneficial for your situation.

Although pipe relining facilitates speedy repairs with minimal disruption, in certain scenarios, pipe replacement may be the better option.
