No-dig pipe relining
across Penrith

A new pipe formed inside the old one. A resin-saturated liner is pulled or inverted into the damaged section, inflated so it presses against the existing pipe wall, and cured hard. What you end up with is a continuous jointless pipe inside the original, sealing the cracks and open joints that roots were getting in through. The old pipe stays where it is and becomes the mould. Nothing is dug up except, sometimes, one small access point.

That is exactly what it is for. Earthenware laid in short lengths with mortared joints is the most common candidate around here, because the failure mode is open joints and root intrusion rather than the pipe material itself being gone. A liner bridges every joint in the lined section at once. What it cannot fix is a pipe that has collapsed or lost so much of its wall that there is nothing left to line against, and the camera tells us which of those you have before anyone quotes.

When the pipe has collapsed, when it has deformed badly enough that a liner cannot seat evenly, when the fall is wrong and the real fault is that water is not draining rather than that the pipe leaks, or when the damaged section is short and sits somewhere easy to reach. If your fault is two metres from an access point under an open lawn, digging it up is faster and cheaper and we will say so.

Not every line needs lining end to end. Where the camera shows one bad joint in an otherwise sound pipe, a patch liner over that spot is the proportionate repair at a fraction of a full run. A full reline earns its price when the footage shows the whole length going: multiple open joints, roots at several points, or a pipe starting to deform. Paying for a full run when a patch would do is the most common way people overspend on this work, and you can see which one you have on the screen yourself.

A properly installed liner is rated for a design life of around fifty years, which is longer than the earthenware it is lining ever managed. Most residential jobs are done in a day, including the camera work before and after. The curing itself is a matter of hours. What extends a job is access and junction work rather than the lining.

The line inside your property is yours to maintain. Once it passes the boundary into Sydney Water's main, it is theirs. The camera establishes which side of that line the fault sits on, and the footage is what you use to make the case. If it is on their side we tell you rather than quoting you for it. Worth knowing that the boundary is not always where people assume, particularly on the older Penrith subdivisions where lots have been reshaped over the years.

Standard residential lining runs about $500 to $900 per metre once we know the length, the diameter and how we are getting in. The camera inspection that has to happen first is $300 to $750 and it is non-negotiable, because quoting relining without seeing the pipe is guessing. Junction reinstatement, a new access pit or any excavation we recommend instead are quoted separately so you can see what you are paying for.
