About Us
Together - Let's Build from the Ground Up!
Northland and North Shore are geologically diverse — from soft estuarine soils around Kaipara Harbour and Marsden Point, to weathered volcanic profiles in the Far North. Accurate ground investigation is essential before any construction, subdivision development, or infrastructure project.
Get ahead of potential ground issues before they become costly problems. Our CPT testing and geotechnical investigations deliver the data your engineer needs for foundation design, liquefaction assessment, land development consent reports, and construction planning — all conducted to CETANZ best practice and ASTM D5778 / ISO 22476-1 standards.
Your land is the canvas. We offer a comprehensive range of geotechnical assessment and soil testing services in Whangarei and North Auckland:

Why Choose Us?
Do It Once, Do It Right
We offer a comprehensive range of geotechnical investigation services: CPT, CPTu, Seismic CPT (S-CPTu), DPSH/DPH/DPM dynamic probing, push tube sampling, hand augured boreholes, Scala penetrometer, Clegg hammer, and Atterberg testing. Our tracked rig accesses sites others cannot — including steep slopes and marshy terrain — with a single operator keeping your project on time and on budget.
Soil testing becomes the key that unlocks the secrets beneath, revealing potential and sustainable progress.
Precision in Every Soil Particle
Our Soil Tests Lead the Way in Whangarei
From soft estuarine clays to dense volcanic profiles, our tracked testing rig reaches sites that conventional equipment cannot — including steep slopes, marshy ground, and areas with restricted access. Single-operator capability keeps your investigation efficient without compromising data quality.
