Auckland's Geotechnical Specialists


Landmark Consultants brings decades of geotechnical expertise to Auckland's unique geological landscape. From our Bucklands Beach office, we serve the entire Auckland region, understanding the complex interplay between volcanic geology, marine deposits, and coastal processes that define Auckland's ground conditions. Our local knowledge combined with advanced testing techniques ensures your project is built on solid foundations.

Auckland's Geological Challenges


Auckland sits on a complex geological foundation that demands specialised geotechnical expertise. Ancient volcanic activity created the region's distinctive cones, while marine processes deposited challenging clay layers across the isthmus.

Our geotechnical engineers navigate these complexities daily - from expansive Waitemata Group clays to weathered volcanic tuffs, from reclaimed harbour land to coastal erosion zones. We understand how these conditions affect foundation design, excavation requirements, and long-term building performance.

Every geotechnical assessment strengthens Auckland's built environment whilst working harmoniously with natural ground conditions.





Volcanic soil analysis

Expert assessment of Auckland's volcanic deposits including East Coast Bays Formation, Waitemata Group sediments, and weathered tuff layers found throughout the region.

Marine clay engineering

Specialised solutions for Auckland's challenging marine clay deposits, particularly critical for CBD developments and harbour-adjacent construction projects.

Liquefaction assessment

Comprehensive liquefaction risk analysis for Auckland's reclaimed land areas and saturated soil zones, ensuring seismic safety compliance.

Coastal site investigations

Detailed geotechnical assessments for Auckland's extensive coastline developments, addressing erosion risks and marine exposure effects.

Ground improvement

Innovative soil stabilisation and ground improvement techniques for Auckland's challenging sites. From deep foundation systems to ground treatment solutions that make difficult sites developable whilst maintaining environmental responsibility.
