CONSULTING

Trenchless expertise from assessment through to delivery

BurrowTech provides practical consulting support for pipeline inspection, rehabilitation and renewal projects.

From reviewing CCTV footage and selecting the right method through to specifications, procurement, onsite support and final sign-off, we help turn complex underground infrastructure work into a clear, deliverable plan.

Why specialist advice

Better decisions before the work begins

No two pipelines, defects or sites are the same. Early specialist input helps identify the right rehabilitation method, reduce project risk and avoid costly changes once work is underway.

Understand the asset

Review CCTV footage, condition reports, drawings and site constraints to build a clear picture of the pipeline and its defects.

Select the right method

Assess the available trenchless methods against the pipe condition, geometry, access, flow and required outcome.

Reduce project risk

Identify technical, access, sequencing and quality requirements before procurement or construction begins.

Create a clear scope

Turn the findings into practical specifications, scopes of work, tender information and a clear path to delivery.

Our process

A clear path from first review to project delivery

BurrowTech can support the complete process or provide specialist input at the stages where it is needed most.

01

Engagement

We begin by understanding the asset, project objectives, programme and level of support required.

02

Discovery

CCTV footage, reports, drawings, access, flow conditions and site constraints are reviewed.

03

Design

Suitable trenchless methods are compared and developed into a practical scope, specification or project plan.

04

Support

We provide technical input during procurement, contractor engagement and preparation for the work.

05

Deliver

Onsite support, quality checks and project documentation help carry the agreed solution through to completion.

Relining standards

We work to recognised relining standards

Our work follows internationally recognised standards from the first CCTV review through to final quality assurance and sign-off.

Relining specifications built around the asset

A successful relining project starts with the right design inputs, product selection and installation requirements.

BurrowTech helps develop practical specifications that account for the condition of the pipeline, structural requirements, operating environment and expected service life.

Key areas we review

Consultancy services

Specialist support at every stage

From the first CCTV review through to installation and final sign-off, BurrowTech provides the technical input needed to plan and deliver reliable trenchless rehabilitation projects.

CCTV review & condition assessment

Accurate rehabilitation planning starts with a clear understanding of the pipeline and its defects.

Method selection & feasibility

We assess the available trenchless methods and identify which options suit the asset, site and required outcome.

Project planning & documentation

Clear, contractor-ready documentation helps remove uncertainty and keep the project moving.

On-site oversight & quality assurance

We provide support during installation to confirm the agreed design, materials and quality requirements are followed.

Global knowledge

Bringing global trenchless knowledge home

BurrowTech works closely with trenchless specialists and manufacturers around the world.

We bring proven techniques, advanced equipment knowledge and international best practice back to New Zealand, then adapt it for our networks, ground conditions and project requirements.

Trenchless methods

Choosing the right method for the pipeline

Different trenchless methods suit different assets, defects and project requirements. We help identify the option that will deliver the best result for the pipeline, budget and required service life.

Cured-in-place pipe (CIPP)

A structural liner is installed inside the existing pipeline and cured using steam, water or UV light. CIPP can renew a damaged pipe without excavation and restore long-term structural performance.

A continuous PVC or composite profile is wound into place inside the existing pipeline. It is well suited to larger diameters and can be installed in some live-flow conditions.

A folded thermoplastic liner is inserted into the pipeline and expanded using heat to create a close-fit lining against the host pipe.

A new pipe is inserted inside the existing pipeline. It is a straightforward and reliable option for assets that are significantly deteriorated.

The existing host pipe is fractured or removed while a replacement pipe is installed. This method is often used where the pipeline also needs to be upsized.

A targeted structural repair is installed over an isolated defect, avoiding the need to reline the full length of the pipeline.

Specialist coatings and repair systems can strengthen manholes, chambers and associated underground structures affected by deterioration or corrosion.

Asset review

Submit an asset for review

Send us the available information, CCTV footage, drawings or reports and our team will review the asset and recommend the next step.

Upload available drawings, reports or images. For large CCTV files, submit the form and we will provide a file transfer option.
