Cone Penetration Testing (CPT)

Unlock detailed subsurface insights with our advanced CPT testing.

We provide comprehensive Cone Penetration Testing (CPT), including Seismic CPT for shear wave velocity and CPTu with pore pressure measurements for accurate soil profiling and groundwater assessment. Our efficient and reliable testing delivers crucial geotechnical data for informed design and construction decisions.

Griffiths is experienced in cone penetration testing (CPT), for reliable geotechnical data to assist with your design and construction decisions on commercial, council and residential projects across the Wellington Region

SMall Diameter Piezometer Installations

Efficient groundwater monitoring installation.

Our specialised service installs small-diameter piezometers directly within CPT boreholes. This cost-effective method provides quick static water levels and long-term monitoring, this minimises site disturbance and installation time. Ideal for detailed hydrogeological information while the CPT Rig is on site.

Our specialised team uses CPT boreholes to install small diameter piezometers for hydrological information

Window Sampling

Fast and cost-effective soil sampling.

Our window sampling technique provides quick, continuous soil profiles for geotechnical and environmental investigations. Ideal for shallow assessments, it's less intrusive and perfect for sites with limited access. Get reliable data efficiently.

Our cutting-edge technology enables us to provide you with window sampling to investigate the geotechnical data you need for your project or to investigate the environmental canvas of an area of New Zealand

Direct Push Sampling

Get undisturbed soil and groundwater samples quickly and efficiently with our Direct Push sampling services.

This versatile technique minimises soil disturbance and provides high-quality samples for environmental and geotechnical investigations. Ideal for rapid site assessments and reaching various depths.

Griffiths provide direct push sampling to assess construction sites across the Wellington Region and North Island-wide

Heavy Dynamic Probe (DPSH)

Need to penetrate dense soils? Our Heavy Dynamic Probe Super Heavy (DPSH) testing provides crucial soil strength data.

We offer DPSH in conjunction with our CPT rig for seamless investigation through challenging layers, maximising efficiency. Alternatively, our lightweight, man-portable DPSH rig allows access to restricted sites. Obtain continuous penetration resistance profiles, essential for foundation design and ground improvement assessments, regardless of site constraints.

Griffiths is experienced with penetrating dense soils with our heavy dynamic probe (DPSH). Pictured is our equipment in front of Wellington Marina and the Interislander. We are Wellington-based but can help with any project across New Zealand

Scala Penetrometer Testing

Measure soil strength with our Scala penetration testing.

Using Scala penetrometers, we accurately assess compaction and shear strength, providing vital geotechnical data. We offer flexible staffing solutions: leverage our skilled geotechnical graduates or our experienced team. Alternatively, we can manage all testing in-house, delivering reliable results efficiently.

Griffiths use scala penetrometers to obtain geotechnical insights thanks to our flexible teams

Hand Augers

Need shallow soil samples in tricky spots? Our hand auger services provide a cost-effective and minimally invasive solution for geotechnical and environmental investigations in confined or sensitive areas. Access tight spaces and gather crucial near-surface data quickly and efficiently.

Field Resources and Logging Services

Services that support fieldwork, including the collection and logging of geotechnical or environmental data, soil samples, and test results. These services are crucial for documenting and analysing subsurface conditions during site investigations.
