Yes. We frequently upgrade or adjust existing drainage infrastructure — including realigning pipes, increasing capacity, or bringing older systems up to current compliance standards. We’ll assess your current setup and recommend the best way forward.
Yes — we can assist during the early planning stages by reviewing site conditions, recommending suitable drainage layouts, and identifying potential compliance considerations. This helps you prepare stronger applications and avoid redesigns later.
Definitely. We can phase our work to suit project milestones — whether you need early drainage infrastructure installed first, or staged installation aligned with subdivision sections or build schedules.
We supply and install all required materials, including pipes, manholes, sumps, and fittings. This ensures compatibility, availability, and efficiency — and removes the hassle of clients sourcing materials separately.
Modern equipment for efficient and adaptable solutions
Every site is different, which is why we invest in modern trenching machinery and excavation gear. Whether your project is on a flat urban site, a sloped rural block, or a tight-access location, our team can adapt our methods to suit the terrain and your specific requirements.
Our equipment and experience allow us to:
- Work efficiently on challenging ground
- Access difficult or restricted sites
- Handle large-diameter pipes and complex layouts
We’re often called in to resolve problems with existing systems, upgrade outdated drainage, or realign pipes for new building footprints. Our local knowledge of Northland’s soils and seasonal water conditions means we can identify potential issues early and plan robust, long-lasting solutions.
