Geotechnical Investigations

Our Focus

Geotechnical investigations are a crucial aspect of any construction project as they provide important information about the subsurface conditions and help to determine the design and construction parameters for a project.

All Hunter Civilab geotechnical investigation are carried out in accordance with AS1726.

Our team of experienced geotechnical engineers gather the necessary data through a range of methods, including:

  • Drilling
  • Soil and Rock Sampling
  • Laboratory Testing
  • Geophysical Testing

The information gathered during the investigation is then used to develop site-specific recommendations and design parameters, including:

  • Type and size of foundation system required
  • Placement of retaining structures and earthworks
  • Suitability of the site for the proposed use

Our team also works closely with other professionals involved in your project, such as architects, engineers, builders and contractors, to ensure that the information gathered during the investigation is used to the best advantage and that the final recommendations are practical and cost-effective.

At Hunter Civilab, we are committed to providing our clients with the highest quality geotechnical investigation services. Our experienced team and state-of-the-art equipment ensure accurate and reliable results that are tailored to meet the specific requirements of each project.

Soils Explained

In geotechnical engineering terms soil includes every type of uncemented or partially cemented inorganic material found in the ground. In practice, if the material can be remoulded by hand in its field condition or in water it is described as a soil in reference to the Unified Soil Classification system.

The consistency of a cohesive soil (clay) is defined by descriptive terminology such as very soft, soft, firm, stiff, very stiff and hard, and its degree of plasticity (low, medium or high).

Relative density terms such as very loose, loose, medium, dense and very dense are used to describe sand and gravel soils, along with their grain size (fine, medium or coarse grained).

Rocks Explained

In geotechnical engineering terms, rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.

There are three kinds of rock: igneous, sedimentary, and metamorphic.

Igneous rocks form when molten rock (magma or lava) cools and solidifies.

Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.

Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water.
