RelinePro trenchless relining work in progress on an Auckland drainage asset

If your sewer or stormwater pipes keep blocking or draining slowly, or your manholes have deteriorated, there is no need for excavation.

Trenchless relining provides permanent structural repair without disrupting your property. Our team are licensed Drainlayers led by Certified Drainlayers. We believe only tradesmen should be working on your valuable drainage assets.

About RelinePro

The smarter alternative to digging

We fix broken sewers, stormwater pipes and manholes without excavation. Established no-dig methods renew the pipe internally, neatly and for the long term.

Our approach focuses on what matters most:

A smarter, cleaner and more reliable alternative to digging up your property.

The warning signs

Is your drain failing?

You might be dealing with:

Recurring blocked drains
Tree roots in pipes
Sewage smells
Sinkholes or wet ground
Cracked or collapsed pipes
Leaking manholes
Old clay or concrete drains

Traditional plumbers dig up your lawn, driveway, floors and concrete.

RelinePro doesn't.

We repair pipes from the inside using advanced structural relining — no trenches, no mess, no delays.

What we do

Core rehabilitation services

Trenchless pipe relining

Restore damaged pipes and manholes from the inside, with no digging, no mess and no disruption to the property.

A durable structural liner forms a new continuous pipe inside the old one, root resistant, corrosion proof and built for the long term.

CCTV drain and manhole inspections

Know exactly what the problem is before any work is done, and avoid both guesswork and unnecessary excavation.

Current generation CCTV cameras identify the defect correctly, which is what makes the repair precise and long lasting.

Drain and sewer rehabilitation

For pipes badly damaged or at real risk of failure, we build structured rehabilitation plans.

They reinforce, stabilise and extend the life of an entire drainage or sewer network, rather than patching one length at a time.

Who we work with

We are the reline specialists other trades bring in.

RelinePro does one thing. We rehabilitate pipes and manholes without digging, and we hand the site back to whoever brought us in.

Civil and drainage contractors

A failed line on a subdivision or civil drainage job, and an excavation that would blow the programme. We reline through existing access points, so the surface, the services around it and your schedule stay intact.

Specified, relined, verified on camera, signed off.

Hydraulic and civil engineers

Our liners form a new self supporting pipe inside the host pipe, structural rather than a coating. Every job leaves with pre and post CCTV footage you can hold against the spec.

Full liner specification available to download.

Plumbers and drainlayers

You hold the drain and you found the defect, but relining is not plant you carry. Bring us in and the reline gets done properly under your job.

We reline. We do not take your customer.

CCTV operators

You are already in the pipe and can see exactly what has failed. Hand the reline to a specialist crew who turn up, work to standard and report back to you.

You find it. We fix it. Your client stays yours.

Property owners and body corporates

A drain that keeps blocking, a failed section of pipe, or shared drainage nobody wants dug up. We reline through the access points already on the property, so driveways, landscaping and floors are never disturbed.

Most residential jobs are done in a single day.

Councils, network operators and asset managers

Live sewer and stormwater networks rehabilitated in place, without a dig and without extended downtime or traffic management. Every asset leaves with pre and post CCTV verification for the asset record.

Manhole rehabilitation

Deteriorated manholes, rebuilt in place.

Most relining companies treat manholes as an afterthought. We do not. A corroded or leaking chamber is rebuilt internally with the same structural approach we use on pipe, with no excavation and no extended network downtime. We install proven Predl manhole bases into existing manholes to rebuild and restore structural integrity.

  • Corroded and spalled chambers
  • Leaking joints and infiltration
  • Failed benching and channels
  • Live network, minimal downtime

Structural pipe relining for long-term performance

Clear diagnostics, verified footage, and practical solutions for lasting pipe performance.

How it runs

Every project follows the same four steps

The result is a pipe that is structurally sound, root proof, watertight and corrosion resistant, and built to last for decades.

  1. 1

    Examination

    HD CCTV cameras pinpoint the exact cause and location of the defect, so nothing is assumed.

  2. 2

    Cleaning

    High pressure washing clears obstructions and returns the pipe close to its original internal diameter.

  3. 3

    Relining

    A durable structural liner is installed, forming a new pipe or manhole within the existing one.

  4. 4

    Verification

    Post installation camera inspection confirms the repair is watertight, and the footage is yours.

What that looks like on the ground

Conventional excavation

Excavation, reinstatement and disruption.

Why RelinePro

Only tradesmen should be working on your drainage assets.

RelinePro is an Auckland based specialist in trenchless pipe relining and manhole rehabilitation, and it is the only thing we do. Our team are qualified Drainlayers led by Certified Drainlayers, because your drainage assets are worth more than a shortcut.

No unnecessary digging
No temporary fixes
No guesswork
Full accountability on every project

Site ready for principal contractor standards

Commercial and municipal principals run strict site regimes, and a crew that cannot meet them costs you access to the site. We trained our crews to standard before we opened the market, and we work to the health and safety requirements of the principal whose site we are on.

Results and outcomes

Measured by what the camera shows afterwards.

Every job leaves with pre and post relining footage, the documentation that supports insurance claims, council requirements, property management records and engineering sign off.
