Soil Testing & Analysis Services


QCTS offer soil testing and analysis for large road construction projects, large commercial projects and residential construction projects throughout Brisbane and Australia wide. Our team are trained to identify any issues with the samples taken using NATA accredited laboratories for testing.


Every construction project needs the project site to be safe to work on, you and your staff need to know what kind of stabilisation your construction projects might need, and what kind of foundations are necessary for the structure or road surface. The only way to know what you are dealing with is through our in-depth analysis techniques and comprehensive soil testing services. QCTS are recognised geotechnical experts, offering our soil testing services throughout Brisbane, Australia wide and throughout South East Asia.

Soil Testing Services

There are a number of things to consider when planning construction on any work site. A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals. The test is used to mimic the function of roots to assimilate minerals.

The quality of soil on your site plays a vital role in all construction projects. As such, you need to identify the quality of the soil to determine the aptness to support your construction project. Soil testing at QCTS will enable you to assess the suitability of the soil, thus providing you with crucial information to make an informed decision.

Our soil testing services will examine your soil’s chemical and geotechnical properties, allowing you to:

  • Determine the suitability of the soil and assess whether it can accommodate your construction project
  • Identify the different types of soil on your site and their location
  • Test your soil for strength, density, compaction, contamination, organics and sand content, and assess their impact on your construction project
  • Gain the data you need to compile technical and safety data reports to support planning permissions and license applications
  • Get precise results and observe the development of the soil throughout your construction project for maximum quality and safety

What is a Site Classification Report?

A Soil Classification Report, typically referred to as a soil test report or geotech report, is a report prepared by a qualified geotechnical engineer on the soil conditions of your site, assessed in accordance with Australian Standard (AS) 2870 ‘Residential Slabs and Footings

A site classification report involves soil testing to define the soil reactivity. Below is a table as per Australian Standards AS2870 outlining the soil classification code and description.


CLASS A Mostly sand and rock with little or no ground movement from moisture changes.
CLASS S Slightly reactive clay sites with only slight ground movement from moisture changes.
CLASS M Moderately reactive clay or silt sites, which can experience moderate ground movement from moisture changes.
CLASS H1 Highly reactive clay sites, which can experience high ground movement from moisture changes.
CLASS H2 Highly reactive clay sites, which can experience high ground movement from moisture changes.
CLASS E Extremely reactive sites, which can experience extreme ground movement from moisture changes.
CLASS P Sites which include soft soils, such as soft clay or silt or loose sands; landslip; mine subsidence; collapsing soils; soils subject to erosion; reactive sites subject to abnormal moisture conditions or sites which cannot be classified otherwise.
