Unearth Possibilities
Assess Soil Strength and Quality at Different Depths
When you choose Soil + Sample, you're working with Northland's dedicated geotechnical testing specialists. As CETANZ members, we conduct all investigations to best practice standards — giving engineers, developers, and councils the reliable ground data they need. We cover Whangarei, Far North, Kaipara, and North Shore, and anywhere else by prior agreement.

Our geotechnical investigations combine CPT testing, dynamic probing (DPSH/DPH/DPM), push tube sampling, hand augured boreholes, Scala penetrometer, and Atterberg testing. From site investigations to foundation design recommendations, we deliver the data engineers and consent authorities need — conducted to CETANZ best practice standards.
We collect undisturbed soil samples using push tube, DS44, and Shelby sampling methods — providing the laboratory specimens your engineer needs to assess bearing capacity, consolidation, and soil classification. Suitable for both shallow and deep investigations across Northland and North Shore.
Our CPT services include standard CPT, piezocone testing (CPTu) with pore pressure measurement, and Seismic CPT (S-CPTu) for shear wave velocity profiling. We also carry out DPSH, DPH, and DPM dynamic testing — giving engineers a complete picture for foundation design, liquefaction assessment, and settlement analysis.
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.
