What is sewer relining

Fix your sewer pipe without excavating the yard

Sewer relining repairs damaged house sewer pipes from the inside using an epoxy resin liner. The liner is inserted through an existing access point, inflated to press against the sewer pipe walls and cured in place — creating a new seamless pipe within the old one. No trench required in most cases.

Sewer pipes in Sydney are particularly vulnerable to root intrusion through clay joints and deterioration over time. Relining resolves the structural damage permanently rather than clearing roots repeatedly. The result is a smooth, root-proof sewer pipe with a 50-year structural warranty.

Warning signs

Signs your sewer pipe may need relining

Sewer pipe problems rarely resolve themselves — and they can get worse and more expensive over time.

Sewage smell inside or outside
Persistent sewer smell from drains or around the yard can indicate a cracked sewer line allowing gas to escape.
Wastewater backing up
Multiple fixtures backing up at once often points to a problem with the main sewer line rather than individual drain branches.
Lush or wet patches in the yard
Unexpectedly green or wet ground over the line of your sewer pipe can indicate a leak from a cracked or failed joint.
Recurring root blockages
If roots keep growing back in the sewer line despite clearing, there are joints or cracks giving them entry.
Older clay or earthenware sewer
Sydney has many older properties with clay house sewers that have deteriorated, cracked or settled over decades.
Shared sewer line issues
For strata and apartment buildings, shared sewer lines need specialist assessment and documentation before repair.

Our process

The sewer relining process

Camera inspection, cleaning, liner installation and final verification — all in one visit in most cases.

Sewer camera inspection

We run a CCTV camera through the house sewer line to identify the damaged sections, measure pipe size, confirm access points and determine whether relining is appropriate.

High-pressure clean the sewer

The sewer line is cleaned with high-pressure jetting to remove root intrusion, debris and buildup, preparing the pipe surface for the liner to bond correctly.

Insert and cure the liner

An epoxy-saturated liner sized for sewer pipe diameter is inserted through an existing access point, inflated against the pipe walls and cured in place.

Reinstate junctions and verify

Sewer junctions and branch connections are reinstated. A final CCTV inspection confirms the liner is correctly positioned and the repair is complete.

FAQ

Sewer relining questions answered

What is sewer relining?

Sewer relining is a trenchless repair method for house sewer pipes. An epoxy resin liner is inserted into the damaged sewer pipe and cured in place, creating a new structural pipe within the old one — without excavating the sewer line in most cases.

How much does sewer relining cost in Sydney?

Sewer relining typically costs more than drain relining due to larger pipe diameters. A standard house sewer job (10–15m of 150mm pipe) typically ranges from $9,100 to $12,250. Drainr provides a fixed quote after CCTV inspection confirms the scope.

Is sewer relining the same as pipe relining?

Sewer relining is a subset of pipe relining, applied specifically to house sewer pipes and shared sewer lines. The process is the same — CCTV inspection, high-pressure clean, liner insertion and curing — but sewer pipes typically use larger-diameter liners.

Can a sewer pipe be relined if it has multiple damaged sections?

In many cases yes. CCTV inspection identifies the affected sections and the relining scope is designed to cover them. Severely collapsed sections may require excavation, but this is confirmed before quoting.

Do you reline shared sewer lines for strata properties?

Yes. Drainr assesses and quotes sewer relining for strata and managed properties, with CCTV findings, written scope and fixed pricing to support committee or body corporate approval.
