Soil Classification Report Melbourne
Soil Classification Report Melbourne
Geotechnical Engineering Services (GES) provides professional soil classification report Melbourne services for residential and commercial construction projects. Our geotechnical engineers investigate subsurface soil conditions, assess soil reactivity and provide foundation recommendations to assist homeowners, builders, structural engineers and developers with their construction projects.
We conduct geotechnical site investigations and prepare soil classification reports in accordance with relevant Australian Standards, including AS 2870 – Residential Slabs and Footings and AS 1726 – Geotechnical Site Investigations.
GES provides soil classification report Melbourne services to assist homeowners, builders and structural engineers in understanding subsurface soil conditions and selecting suitable foundation systems for residential developments.
What Is a Soil Classification Report?
A soil classification report, also known as a soil test report or geotechnical report, provides information about the subsurface soil conditions of a proposed construction site.
The report identifies soil types, soil reactivity, ground conditions and potential foundation-related risks. It also provides recommendations to assist structural engineers in designing suitable footing systems.
A professional soil classification report is commonly required for new homes, extensions, renovations and other building projects throughout Melbourne.
GES also provides Residential Soil Testing services for new homes, extensions and renovations throughout Melbourne, including site classification and footing recommendations in accordance with AS 2870.
How Is a Soil Classification Report Prepared?
GES conducts site investigations to assess the subsurface conditions at the proposed construction location.
The investigation typically includes:
Site Inspection: Assessment of existing ground conditions, vegetation, drainage, slopes and nearby structures.
Borehole Drilling: Investigation of subsurface soil conditions using suitable drilling or sampling equipment.
Soil Sampling: Collection of representative soil samples for identification and testing.
Laboratory Testing: Relevant soil tests undertaken by our NATA-accredited laboratory within its accredited scope.
Geotechnical Assessment: Evaluation of soil properties, reactivity and potential ground movement.
Engineering Report: Preparation of site classification and foundation recommendations based on investigation findings.
The number and depth of boreholes depend on the proposed development, site accessibility and encountered ground conditions.
Soil Classification in Accordance with AS 2870
Site classification is based on the characteristic surface movement (Ys), soil reactivity and relevant site conditions. For reactive soil sites, the classification assists structural engineers in determining appropriate slab and footing design requirements. Sites affected by abnormal conditions, including uncontrolled fill, significant vegetation influences or other geotechnical constraints, may require classification as Class P and additional engineering assessment.
AS 2870 provides a framework for classifying residential building sites based on expected ground movement and relevant site conditions.
Common site classifications include:
Class A: Most sand and rock sites with little or no moisture-related ground movement.
Class S: Slightly reactive clay sites.
Class M: Moderately reactive clay or silt sites.
Class H1: Highly reactive clay sites.
Class H2: Very highly reactive clay sites.
Class E: Extremely reactive sites.
Class P: Problem sites affected by abnormal conditions requiring specific engineering consideration.
The final classification depends on the subsurface conditions, soil reactivity and other site-specific factors.
What Is Included in a Soil Classification Report?
A professional soil classification report Melbourne property owners and builders can rely on may include:
Site description and investigation methodology.
Borehole logs and subsurface soil profiles.
Soil identification, consistency and plasticity.
Groundwater observations during investigation.
Site classification in accordance with AS 2870.
Assessment of characteristic surface movement, where applicable.
Recommended founding depths.
Allowable bearing pressures for suitable footing systems.
Bored pier design parameters, where required.
Relevant laboratory testing results.
Why Is Soil Classification Important Before Construction?
Melbourne contains a wide range of soil conditions, including reactive clay, sandy soils, fill materials and weathered rock.
Reactive clay soils can shrink during dry conditions and swell when moisture levels increase. These changes may cause differential ground movement and affect building foundations.
A professional geotechnical investigation helps structural engineers select appropriate footing systems and reduce the risk of foundation-related structural damage.

Frequently Asked Questions
Is a Soil Classification Report Required Before Building?
A soil classification report is commonly required to assist with residential footing design. Specific requirements depend on the proposed development and applicable building approval conditions.
What Is the Difference Between Class M and Class H Soil?
Class M indicates moderately reactive soil, while Class H1 and H2 indicate higher levels of reactivity and potential ground movement.
What Does Class P Mean in a Soil Report?
Class P identifies a problem site where abnormal conditions such as uncontrolled fill, vegetation effects, unusual moisture conditions or other site constraints require specific engineering consideration.
How Long Does Soil Testing Take?
The investigation duration depends on site accessibility, borehole requirements and ground conditions. Reporting time also depends on the scope of investigation and laboratory testing requirements.
