No-dig pipe relining
across Leichhardt

A resin-soaked liner is drawn through the existing pipe, inflated so it presses against the wall along the whole length, then cured until it hardens. What you end up with is a continuous pipe formed inside the old one, with no joints along the lined section. Joints are where roots enter and where gaps open, so removing them is the point. The old pipe stays put and acts as the mould, so nothing has to be excavated.

By giving back capacity, which around here is the thing that matters. The stormwater system discharges to a tidal outlet, so on some days there is simply less fall available and the margin between coping and backing up is small. An old line has quietly given away a good part of its original capacity to root intrusion, silt caught on rough surfaces and lengths that have dropped slightly. A cured liner is smooth, straight and jointless, so it carries more than the pipe it was formed inside. That recovered margin is often exactly what the property needed.

We will not promise that, and you should be wary of anyone who does. Relining restores your side of the system to its proper capacity. It cannot change the level of a tidal outlet or alter a council stormwater asset, and if a property is genuinely below the level the system can serve on a high tide, no amount of pipework fixes that. What it does is make sure the part you control is not the thing letting you down.

Yes, and here it is frequently the more useful of the two. The principle is identical: a liner cured inside the existing pipe, sealing joints and restoring a smooth bore. Stormwater lines on older inner-west properties are often the ones nobody has ever looked at, which is why they are also often the ones quietly running at a fraction of their rated capacity.

Usually, and the small block is part of the argument. What rules lining out is a section that has genuinely collapsed or been crushed, or one so far gone there is nothing left to press against. The camera settles that before anyone quotes and the footage is handed over. On an inner-west block where the alternative is excavating most of a courtyard, lining is very often the only sensible option available.

A sectional patch is usually a few hours. A full run to the boundary is generally most of a working day, and you get the window before we start. Compare that with excavating the same run on a narrow block, which is days of open ground plus reinstating whatever surface was over the top of it.

A sectional patch over one failed joint is about $900 to $2,200. A full run to the boundary is usually $3,500 to $7,000 depending on length, diameter and bends. A camera inspection is $250 to $450 and is credited against the reline if you proceed. We price the excavation alternative beside it so the comparison is honest.
