The Hills is the one place where relining needs a caveat. Reactive clay moves whatever is buried in it, and where that movement has pulled a joint fully apart or dropped a section, a liner has nothing continuous to bond to. Often it still works. Sometimes it does not, and it is better to know before paying for it.

The same line: roots coming through a dislodged joint. Open joints like this are what a liner is designed to seal.

More roots growing into the old clay pipe, through dislodged joints and hairline cracks. The camera shows where a pipe is damaged before anyone quotes a repair.

Reactive clay cracks pipe and separates joints. A liner repairs cracks and minor separations well; a fully dropped section needs excavating, and the camera shows which you have.

Big homes mean long drainage runs with many joints. Lining a whole section at once is more economic than repairing failures one at a time.

Newer estates have substantial paving, driveways and pools built over drainage. Reinstatement is the expensive half of any excavation.

Fixed price quoted before we start. $0 call-out fee.

How It Works

01

We camera your drain to assess the damage and confirm relining is the right solution.

02

We jet blast the pipe to remove roots, debris, and build-up before lining.

03

A resin-impregnated liner is inserted and inflated, then cured in place — typically within hours.

04

We camera the pipe again to confirm the lining is smooth, sealed, and flowing freely.

Common Questions

A liner is more flexible than the clay pipe around it and tolerates movement better. Where a section has already separated completely it needs excavating instead — we will tell you which you have.

In the Hills that usually points to soil movement cracking the pipe rather than anything you have done. It is a structural fault, and clearing will not keep it clear.

Always. On reactive clay it is the only way to know whether a liner is the right product.
