Pipe Patching vs Pipe Relining: What’s the Difference?

Introduction to Pipe Repair Methods

When pipes under your Petersham home start leaking or get blocked, a prompt repair is essential to prevent further damage. Instead of the major excavation work of the past, modern methods like pipe patching and relining offer faster, less disruptive fixes focused on the affected section.

Pipe patching involves inserting a pipe patch to cover holes or cracks from corrosion, tree roots, settling, etc. Relining, on the other hand, inserts a tube inside the pipe to form a smooth new barrier.

It only repairs the area pipe rather than replacing the whole pipe. Both methods avoid extensive dig up of your garden.

This article will explore pipe patching relining vs detail, outlining the procedures, applications and advantages of each repair technique. We’ll provide advice to help determine what pipe offers the most affordable long-term solution for various piping issues.

What is Pipe Patching?

Pipe patching is an innovative plumbing repair technique used to fix broken pipes and isolated damage without replacing entire sections. It inserts an epoxy-coated composite patch over cracks, holes, joint leaks or corrosion in tricky areas like under concrete or structures. This precisely targets the affected region for a reliable, long-term repair.

As a minimally invasive surgical method in plumbing, pipe patching can get the job done without major digging to access pipes. It is well-suited for minor leaks or blocked drains caused by tree roots, ground shifting or ageing pipes. High-pressure water jets first clean out your drain, allowing custom-fit epoxy patches to seal sections less than one metre long.

The composite binds securely to the damaged pipe to form a durable barrier.

Compared to relining or replacing whole pipe runs, pipe patching is extremely cost-effective. It also minimises disruption to gardens and landscaping. Petersham homeowners can benefit from this innovative technique for only small, isolated pipe issues in hard-to-access areas.

How Pipe Patching Works

The pipe patching process involves several key steps:

1. Initial CCTV pipe inspection: High-resolution cameras scope the drain pipe to identify damage locations and suitability for patching.
2. Localised cleaning: High-pressure water jets scour the pipe interior at the fractured spot to allow patch adhesion.
3. Measurement and customisation: The pipe dimensions are used to cut epoxy composite patches for a perfect fit.
4. Application: Patches get inserted through the cleanout or manhole and adhere to the damaged area, sealing leaks or holes.
5. Further testing: Cameras confirm the watertight pipe patch application before backfilling.

The heat-cured epoxy patches chemically meld with pipes once applied, increasing structural integrity. This method reinforces existing pipes rather than replacing entire sections.

For small, isolated pipe issues under 1 metre, patching avoids major landscaping disruption while offering long-term reliability. It’s an affordable, minimally invasive solution for localised fractures or breaks in tricky areas.

When to Use Pipe Patching

Pipe patching is the optimal solution in these scenarios:

• Isolated pipe damage under 1 metre long such as fractures, holes or joint separations
• Leaks or blockages due to tree roots, ground shifting or general wear in awkward areas
• Pinpoint repairs needed under structures, buildings, pathways or landscaped gardens
• Minor pipe issues in drain or sewer lines running under driveways
• Areas where minimal excavation is desired for cost savings or to limit disruption

The key advantage of the pipe patching method pipe is precisely targeting small damaged sections rather than digging up and replacing entire pipe runs. As a surgical fix, it is highly cost-effective and less invasive compared to relining or traditional drain repairs involving excavators.

Petersham homeowners can benefit from pipe patching for isolated pipe leaks, fractures or blockages located in hard-to-access spots. This innovative method offers long-term reliability without destroying landscaping or pathways.

Understanding Pipe Relining

Pipe relining is another trenchless repair method that inserts a protective liner inside damaged pipes to reinforce them. It is well-suited for extensive deterioration along sections longer than a metre, restoring flow capacity and sealing leaks.

The process begins like pipe patching, using CCTV cameras to inspect pipe interiors and determine if they are suitable candidates for relining based on material and amount of damage. Polyethylene or epoxy-resin liners then get saturated with a bonding solution and fed through the pipe.

Once in position, the liners expand by air or steam pressure, moulding tightly to cracked or corroded sections to form a smooth new barrier. Custom-fitted to each pipe’s shape, they seal leaks and restore flow while avoiding pipe replacement or digging through gardens or driveways.

Compared to patching smaller areas, relining offers comprehensive reinforcement for whole pipe sections up to 70 metres long. It protects against further corrosion and infiltration while restoring drainage capacity. As a durable yet affordable trenchless repair, relining keeps disruption to a minimum.

The Pipe Relining Process

The pipe relining process involves several key phases:

1. CCTV inspection: High-resolution cameras thoroughly scope the drain line’s condition and suitability for relining.
2. Cleaning and preparation: Specialist equipment scours the pipe walls, then a threaded liner tube gets saturated with epoxy resin.
3. Installation: The resin-coated tube gets fed through the pipe and inflated by air pressure to adhere tightly.
4. Curing: Steam or UV light cures the resin fully to solidify the custom liner now formed within.
5. Final CCTV check: Cameras confirm an integrated barrier with restored water flow and leak proofing.

The expandable liner moulds itself to each pipe’s unique shape for a perfect seal. As the epoxy resin cures rock-hard, it fuses securely to repair cracks, gaps and corrosion damage along the entire length. This restores structural stability and pressure resistance.

Compared to patching isolated areas, relining offers comprehensive reinforcement for pipe sections up to 70 metres long. It keeps pipes intact under gardens or driveways without major digging or replacement.

Situations Where Pipe Relining is Best

Pipe relining is the optimal trenchless repair method in these situations:

• Extensive deterioration along pipe sections longer than a metre
• General cracks, gaps, blockages or root intrusion affecting flow
• Multiple leaks or collapses weakening stability along a length of pipe
• Restoring drainage capacity and water pressure to ageing drain lines
• Reinforcing pipes under gardens, driveways or other hard-to-access areas

Compared to patching isolated issues, relining offers comprehensive reinforcement for whole pipe sections up to 70 metres long. It is a cost-effective way to avoid major excavation or replacement of pipes running under properties.

As an affordable, long-term solution, Petersham homeowners can rely on pipe relining to tackle extensive damage or deterioration affecting larger portions of critical drain and sewer lines.

Comparing Pipe Patching and Relining

When weighing up trenchless drain repairs, key differences help determine whether pipe patching or relining is most suitable:

In short, pipe patching offers an affordable fix targeting minor isolated issues, while relining tackles extensive deterioration along longer sections. Both avoid digging up gardens and landscaping.

Cost Comparison

When weighing up trenchless drain repairs, cost considerations include:

• Initial expenses: Pipe patching starts around $350 for basic patches, with relining from $2500 covering larger sections.
• Labour: Patching takes 1-2 hours on site for small repairs, while relining may occupy a full workday due to curing times.
• Restoration: Neither method requires digging so no gardens or driveways need reconstruction.

The selected option comes down to pipe length and damage extent. Although relining costs more upfront, it can provide better value for reinforcing deteriorated sections over a metre long term. Pipe patching offers affordable, minimally invasive repairs for isolated issues.

As surgical solutions without excavation expenses, both methods provide cost savings and convenience compared to traditional drain repairs. Petersham homeowners can discuss repair options with experts to determine the most suitable trenchless solution.

Longevity and Durability

When assessing the lifespan of trenchless drain repairs, relined pipes deliver exceptional durability, lasting 50 years or longer. The resin-saturated liners fuse to form a robust, corrosion-resistant barrier that maintains integrity even under driveways.

Patched pipes offer more variable longevity depending on pipe material and proper application. But quality epoxy patches still provide 10 to 15 years of reliable service sealing leaks and blocking roots in isolated areas. Avoiding destructive excavation is key to extended performance.

In contrast, traditional drain repairs involve digging up pipes and replacing damaged sections entirely. Although effective, this disturbance leaves them vulnerable to future settling, movement and root regrowth. Lifespans range from 20 years for orangeburg pipe to 50+ years for PVC.

For lasting value, Petersham homeowners can rely on expertly applied pipe patching and relining. With comprehensive sealing and added structural strength, these surgical solutions deliver the greatest pipe durability and longevity without digging up gardens.

Selecting the Right Repair Method

Determining the ideal trenchless drain repair comes down to pipe length, damage extent, location and budget. Although relining offers exceptional durability for deteriorated sections over a metre, pipe patching provides a highly affordable fix for isolated issues under $500.

We recommend Petersham homeowners contact specialist plumbers to assess damage and advise the best solution. Factors like pipe material, age, soil type and access play a role in suitability. Professional drain scoping with CCTV cameras determines whether patching or relining is preferable for specific issues.

In general, pipe patching tackles minor leaks, cracks and blockages very cost-effectively. It’s perfect for quick repairs in awkward spots. Pipe relining comphrehensively reinforces pipe interiors when more advanced deterioration exists along longer portions.
