CPT Testing

Where Innovation Meets Groundbreaking Insight

For engineering and construction projects in Whangarei, we have a soil-tastic solution and that’s CPT.


Cone Penetration Testing (CPT) is a fast, efficient, and affordable approach to get vital information. It is a geotechnical method used to assess the subsurface properties of soil.


As we love to dig around, what we do in a CPT test is we push a cone-tipped probe into the ground at a constant rate, continuously measuring resistance as it penetrates different soil layers.

Precision Insights

Obtain accurate and detailed information about soil composition and properties.

Efficiency

CPT allows for rapid data collection, reducing time and costs compared to traditional methods.

Real-time Analysis

Receive immediate on-site results, enabling prompt decision-making during the testing process.

Comprehensive Data

Assess soil strength, stratigraphy, and other key parameters for a holistic understanding. Utilises a smaller cone for investigations in confined spaces or areas with limited access.

CPT Testing Whangarei: Your Geotechnical Ally


Let’s kick a few rocks out of the way - Cone Penetration Testing (CPT) is a widely employed geotechnical investigation intended for foundation design, site suitability assessments, and a method in understanding the mechanical properties of the subsurface materials.


Unparalleled accuracy allows this technology to reveal hidden truths, CPT in a good way can direct your building choices toward strong foundations - guaranteeing a successful project in your unique location.

FAQs - Cone Penetration Testing (CPT)

Whether you're new to CPT or seeking a deeper understanding, explore our commonly asked questions here at Soil + Sample and get to know more about this powerful geotechnical method.

1. What is Cone Penetration Testing (CPT)?

Cone Penetration Testing is a geotechnical method that involves pushing a cone-tipped probe into the ground to measure soil properties. It provides valuable data on soil composition, strength, and stratigraphy.

2. How does CPT differ from traditional drilling methods?

Unlike traditional drilling methods, CPT is non-intrusive and minimises soil disturbance. It allows for real-time data collection during penetration, offering a more efficient and cost-effective approach to geotechnical investigations.

3. What information does CPT provide?

Our CPT testing in Whangarei provides information on cone tip resistance, sleeve friction, and pore water pressure. These parameters help in assessing soil strength, stratigraphy, and hydraulic characteristics, essential for foundation design and construction planning.

4. In what types of projects is CPT commonly used in Whangarei?

CPT is commonly used in a variety of projects around Whangarei, including foundation design for buildings, bridges, and offshore structures. It's also employed in environmental assessments, infrastructure development, and geotechnical investigations for soil characterisation.

5. Is CPT suitable for all soil types?

Yes, CPT is versatile and can be applied to various soil types, including sands, clays, and silts. Its adaptability makes it a valuable tool in Whangarei geotechnical engineering, offering insights into soil behaviour across different geological conditions. Call us at Soil + Sample to know more.
