What’s Involved In Satellite Junction Repair?

We use the latest SteamBox technology to repair cracked junctions without expensive and labour-intensive excavation. Our satellite  junction repair involves lining an inflatable 3 way bladder with epoxy or silicate resin and inserting it into the pipe junction. The bladder is inflated into the shape of the junction and cured with the aid of circulated steam or ambient air. 

The SteamBox allows us to apply precise pressure and temperature control to speed up the curing process while inflating the bladder in a single step. This gives you perfectly repaired, brand new pipe junctions. It also saves you time, money, and the hassle of disrupting your personal or business schedule.

Before repairing your pipe junction, we use CCTV drain cameras to locate and identify the pipe junctions and needed repairs. All blockages or obstructions are removed with high-pressure drain jets and robotic drain cutters. A final check using drain cameras is carried out to ensure that the junctions have been repaired perfectly, with recorded footage and images for proof of work.

We repair all types of junctions, including stormwater, sewer, copper, cast iron, pvc, clay and asbestos. Our pipe rehabilitation services include sectional and complete pipe repairs using the latest technology and innovative repair techniques.

Why Should Sewer Sidelines Be Maintained—And Who Should Do It?

It’s important to remember that, although your sewer sideline connects to the main public sewer, as the property owner, you’re responsible for maintaining the section of pipe that runs from your property right up to the sewer main. This stretch is where most issues occur, such as blockages or cracks, and these problems can quickly cause sewage backups or water damage if not addressed.

Regular upkeep by a licensed and experienced plumber is essential for several reasons:

  • Prevents Costly Repairs: Routine inspections and maintenance help catch minor issues before they turn into major (and expensive) problems.
  • Ensures Proper Flow: Keeping your sewer sideline clear makes sure wastewater flows smoothly away from your home or business—not back into it.
  • Protects Your Property: Avoiding blockages and leaks protects your foundation, landscaping, and the overall value of your property.
  • Compliance and Safety: Professional plumbers know how to spot issues that may violate council regulations or pose health and safety risks.

By booking scheduled inspections and maintenance with a qualified technician, you reduce the risk of unexpected emergencies and prolong the life of your pipes.

Are property owners responsible for maintaining sewer sidelines?

Yes, as the property owner, you are generally responsible for maintaining the sections of sewer line—often known as sewer sidelines—that run from your property up until they connect to the main council or Sydney Water sewer system. This means any blockages, cracks, tree root intrusions, or general wear within these pipes are yours to look after.

Most issues with sewer drainage tend to happen within these privately-owned sections, causing blockages or backups. To prevent costly disruptions or potential damage to your home or business, it’s recommended to schedule regular inspections and maintenance with a licensed plumber. Proper upkeep ensures your system continues flowing smoothly and helps you avoid unexpected surprises.

Why Protect Sewer Infrastructure During Construction?

Sewer mains are vital assets that keep Sydney’s plumbing system running safely and efficiently—think of them as the hidden highways that whisk away wastewater from homes and businesses. When building or digging near sewer lines, it’s crucial to take every precaution to protect these pipes from accidental damage.

Unintentional harm to sewer infrastructure can lead to costly repairs, environmental contamination, blockages, and service disruptions. It can even pose health risks if leaks or breakages occur. By safeguarding the sewer system during any building or excavation work, you help maintain the integrity of Sydney’s water management network and avoid unnecessary headaches down the track. This proactive approach ultimately saves time, money, and hassle for everyone involved.

Why Are New Junctions and Sewer Sidelines Needed for Subdivisions and Developments?

When subdividing land or developing new properties, it’s often necessary to add new pipe junctions or extend existing sewer lines—known as sewer sidelines—to meet modern plumbing needs. These connections ensure each dwelling or new lot can access the main sewage system safely and efficiently.

For example, if you’re building on a battle-axe block set back from the street, a sideline might be constructed to run from the main sewer out to your property. Similarly, if you’re adding a granny flat, duplex, or extra unit, you’ll likely need additional junctions so that each can connect independently to the sewer network.

By installing new junctions and sidelines, plumbers ensure wastewater is diverted appropriately without overloading or damaging the existing system. This approach also helps future-proof your property as requirements change—ensuring reliability whether you’re updating a single home, subdividing, or building a multi-unit development.

Pipe Sizes and Compatibility

Our advanced repair systems are engineered to handle a wide range of pipe diameters typically encountered in Sydney infrastructure projects. Whether you’re dealing with older, narrower lines or larger, modern sewer mains, we have the right equipment and materials for the job.

  • Nominal pipe sizes from 100mm up to 250mm can be rehabilitated effectively with our mobile SteamBox technology—perfect for both domestic and commercial applications.
  • Components such as liners, flexible bladders, and specialised junction heads are available in standard profiles for junctions, bends, and reducers typically found in sewer and drainage networks.
  • Custom sizes and configurations, including larger junctions and unusual bends, can also be accommodated through pre-order to meet unique site requirements.

With this versatility, we can confidently address everything from tight residential bends (with flexibility up to 87° on DN 100 pipes) to complex junction repairs in larger trunk lines. No matter the scope of your project, our repair solutions are tailored for long-lasting results across every major pipe size in use throughout the Greater Sydney area.

Compatible Head Sizes for Pipe Repairs

Our advanced equipment supports a wide range of pipe diameters, making it easy to tackle most residential and commercial junction repairs.

Using advanced relining materials and installation techniques, we can rehabilitate pipes that curve up to about 87 degrees, starting from common sizes like DN 100 (100mm diameter). This means even those tricky corners under your floor or driveway are typically within reach, eliminating the need for disruptive excavation.

This high level of adaptability ensures a seamless repair around bends, T-junctions, and other complex configurations—keeping your entire wastewater system flowing smoothly and reliably.

Frequently Asked Questions

Our satellite pipe junction repair involves the use of specialised SteamBox technology to fix cracked or damaged sections of underground pipes where two or more pipes connect. We start by lining a 3-way inflatable bladder with silicate resin or epoxy and inserting it into the damaged junction. Once there, we inflate the bladder so that it takes the shape of the junction and then allow it to cure.
Yes, the process typically involves sealing the entire junction where two or more pipes come together. This is done to prevent leaks and ensure that the pipes can continue to function properly.
Several materials can be used to seal cracked pipe junctions, however, we normally use silicate resin or epoxy to seal the cracks or leaks because of their strength and durability. These materials create a watertight seal and can withstand a range of temperatures and environmental conditions.
Epoxy or silicate resin is typically cured by exposing it to air or heat after it has been applied to the inner surface of the pipe junction. We use circulated steam or ambient air to cure the liner. The SteamBox provides accurate pressure and temperature control to speed up the curing process, giving us a perfectly repaired and sealed pipe junction.
