Geotechnical

We have extensive knowledge of Whangarei soil. Let Soil + Sample navigate the ground beneath for a foundation that stands the test of time.

From dirt to data, geotechnical soil services tell you a lot about the physical and mechanical qualities of the soil at a certain location.


Understanding the soil conditions is crucial to determine whether the site can support the intended structures. Our geotechnical services Whangarei are essential in various industries and construction projects. Here are some of the key benefits:

Site Suitability Assessment

If you want to know if the site can hold the constructions you have in mind, you need to know the soil conditions. Our Whangarei geotechnical investigations help assess the suitability of a site for construction projects.

Foundation Design

Breaking ground is no easy feat. Different soil types require different foundation designs, and through our geotechnical services this can help engineers choose the most suitable foundation type for the specific soil conditions.

Risk Management

Let us help you identify potential risks such as soil instability, landslides, or settlement issues. This information is crucial for risk management and can inform mitigation measures to ensure the stability and safety of structures.

Construction Planning

Knowing about the properties of the soil helps with planning building projects better. This makes it less likely that there will be delays or problems that come up out of the blue.
