Every building consent application in Northland requires geotechnical input. Core Engineering carries out thorough site investigations and prepares reports that councils can act on — giving your designer the foundation parameters they need and giving council the information required for consent approval.
We use industry-standard equipment and testing methods — hand augers, dynamic probe (DPSH), CPT (cone penetration testing), trial pits and laboratory testing — selected for the specific requirements of your site and project type.
Geotechnical investigations and reports are essential components of the planning and design process for construction projects, particularly those involving structures and infrastructure. These services are provided by Whangarei geotechnical engineers and geologists to assess the subsurface conditions of a site.

Report Preparation

Core Engineering geotechnical reports are written to directly support building and resource consent applications with Whangarei District Council, Kaipara District Council, Far North District Council and Northland Regional Council. Our reports provide the foundation parameters, ground hazard assessments and geotechnical recommendations your designer and council need.
Expertise That Digs Deep
Our CPEng-qualified geotechnical engineers have direct hands-on experience across Northland ground conditions — from soft alluvial soils and peat in low-lying Whangarei Basin areas, through to volcanic terrain around the Bay of Islands, sandy coastal formations at Mangawhai and Bream Bay, and heavy clay soils throughout the Kaipara District.
Comprehensive Solutions
No two projects are the same. That's why we offer customised geotechnical solutions to meet your specific needs. From soil sampling to rock mechanics tests, we cover the full spectrum of services to ensure a thorough understanding of your site.
Mitigate Risks
Our reports identify and quantify geotechnical hazards — including liquefaction, slope instability, compressible soils, expansive clays and aggressive groundwater — and provide specific recommendations to manage these risks in your project design.
Timely, Cost-Effective, and Reliable
We understand that geotechnical investigations are often on the critical path for consent applications. We schedule site visits promptly, use efficient testing methods and write reports that are clear and council-ready — not padded with unnecessary caveats.
