Ready Set Reline is a pipe relining and junction repair specialist based in Roseville on Sydney’s North Shore, with experience across homes, strata, commercial sites and council infrastructure. Our owner Ryan trained on-site at the Brawoliner factory in Germany, and every job is run to that standard. Repairs comply with the Plumbing Code of Australia and use WaterMark-approved materials meeting AS/NZS 3500, and you deal directly with the crew doing the work, never a subcontractor.
What is it?
What is Satellite Junction Repair?
Satellite junction repair is a trenchless method of rebuilding a cracked or leaking sewer junction, the point where a branch pipe meets the main line, from inside the pipe, without excavation. A three-way inflatable bladder is coated with epoxy, silicate, or UV resin and positioned at the damaged junction. The bladder inflates to take the exact shape of the junction, including the branch, and the resin is cured with circulated steam or ambient air. Once cured, the bladder deflates and withdraws, leaving a seamless, watertight junction bonded to the original pipe.
We use our 3-way satellite technology to inflate the bladder and control pressure and temperature in a single step, which cures the resin faster and more consistently than open-air methods and produces a repair that seals the full junction, not just one leg of it.
Why you need an expert
Why Junctions fail and why they’re the hardest part of the pipe to fix
A junction is the weakest point in any drainage system. It’s where two pipes were joined by hand, often decades ago, and where the pipe changes direction and diameter. Ground movement concentrates stress there, and the mortar or collar sealing the connection degrades long before the pipe itself does.
That’s also why tree roots find junctions first. A hairline gap at a joint releases moisture and nutrients into the soil, and roots grow directly toward it. Once inside, they widen the crack every season.
Conventional repair means excavating to the junction and junctions are usually the deepest point of the run, frequently under a driveway, a paved courtyard, a retaining wall or a boundary fence. The digging is rarely the biggest cost. Reinstating what was above it is.
Relining a straight section of pipe is comparatively simple. Rebuilding a junction requires a liner that forms itself into a three-dimensional shape and seals in two directions at once which is exactly what satellite junction repair does, through an existing access point.
Responsibilities
Boundary Traps and Sewer Junctions – Who is actually responsible?
This is the question that decides who pays, and most Sydney property owners get it wrong.
You own the pipes on your property, right up to the connection point with the Sydney Water main. That section, often called the sewer sideline, is yours to maintain, including its junctions and, in most older Sydney properties, the boundary trap.
A boundary trap is a water-sealed fitting near your property boundary that stops sewer gases from the main travelling back up your line. Sydney Water required them on most connections historically, which is why they’re so common across the older suburbs of the North Shore, Inner West and Eastern Suburbs. They’re also a frequent failure point, the trap sits at the deepest, oldest part of your line, and cracked or collapsed boundary traps are one of the most common causes of a persistently blocked sewer.
Thankfully boundary traps and boundary junctions can very often be repaired using the same trenchless method, from inside the pipe. We’ll confirm on camera exactly where the fault sits relative to the connection point, so you know precisely what’s yours before you spend anything.
Step-by-Step
Our Satellite Junction Repair Process
Free CCTV inspection
High-definition drain cameras locate the junction, assess the damage and confirm its position relative to your boundary. You see the footage.
Fixed written quote
One price, agreed before we start. Comparable written quote elsewhere? We’ll beat it by 10%.
Clean and prepare
High-pressure jetting removes roots, grease and debris, and robotic cutting grinds out hard obstructions and intruding roots so the resin bonds to a clean surface.
Position the bladder
A three-way bladder coated in epoxy, silicate or UV resin is inserted and positioned precisely at the junction.
Inflate and Cure
We inflate the bladder into the junction’s exact shape and cures the resin under controlled pressure and temperature, using circulated steam or ambient air.
Final CCTV inspection and handover
We re-inspect on camera, confirm the seal, restore flow, and hand over recorded before-and-after footage as proof of work plus your warranty documentation.
Where it works well
Pipe sizes, bends and Junction types we repair
Junction types: sewer and stormwater junctions, T-junctions, branch connections, boundary junctions and boundary traps, bends and reducers.
Pipe materials: clay, earthenware, terracotta, PVC, cast iron, copper and asbestos cement.
Sizes and capability:
Repairing Junctions for Subdivisions, Granny Flats and Duplexes
A battle-axe block set back from the street needs a sideline run out to the main. A granny flat, duplex or additional unit have their own junction so it can connect independently.
We repair junctions for:
Getting this right matters beyond the immediate job. Junctions divert wastewater without overloading the existing line, and protecting the sewer main during construction avoids the contamination, blockages and service disruptions that come with accidental damage to it.
Service Area
Suburbs we serve across Sydney
Ready Set Reline is based in Roseville and delivers pipe relining services right across Sydney. We work daily through the North Shore, Lower North Shore, Northern Beaches, Eastern Suburbs, Inner West, Hills District and the CBD.
These are exactly the areas where pipe relining earns its keep. Sydney’s established suburbs are full of pre-war homes on leafy streets, where original earthenware and clay drains sit under mature trees, heritage gardens and paved driveways. Digging is expensive and often restricted, relining from the inside is not.
