At BurrowTech, we provide specialist consultancy for trenchless pipeline rehabilitation across New Zealand. We combine global expertise with deep local knowledge to deliver solutions that are technically sound, aligned with recognised relining standards, and tailored to the unique challenges of every project.
From CCTV reviews to full rehabilitation planning, documentation, and onsite oversight, we partner with clients throughout the entire trenchless process—ensuring the right method is selected, designed, and executed for long-term asset performance.
No two pipelines behave the same. Ground conditions, flow characteristics, deterioration patterns, access constraints, asset materials, and environmental factors can vary dramatically between sites.
This means:
Getting this right is not guesswork. It requires specialist trenchless knowledge, practical experience, and an understanding of how global best-practice translates into New Zealand’s unique conditions.
This is where BurrowTech excels.
Our work follows internationally recognised relining standards, ensuring:
We apply these standards from the first CCTV review right through to final QA and sign-off.

Different trenchless methods suit different applications. We help you understand which system will deliver the best result for your pipeline, budget, and desired service life.
Cured-In-Place Pipe (CIPP)
A structural liner installed within the existing pipeline, cured with steam, water, or UV light.
Spiral Wound Lining
A continuous PVC or composite profile wound into place, ideal for large diameters and live-flow installation.
Fold-and-Form Lining
A folded thermoplastic liner inserted into the pipe, then expanded with heat to form a tight, close-fit solution.
Slip Lining
Insertion of a new pipe into the old one—simple, reliable, and ideal for significantly deteriorated assets.
Pipe Reaming & Pipe Bursting
Fracturing or removing the host pipe while installing a replacement pipe, often used when upsizing is required.
Patch Repairs
Targeted structural repairs for isolated defects without full relining.
Structural & Manhole Repairs
Advanced coatings and repair systems to strengthen chambers, manholes, and associated structures.
