Understanding Melbourne's Soil Conditions
Melbourne's geological environment presents specific challenges for residential construction. Our team's expertise ensures accurate assessment of these varied soil conditions across metropolitan Melbourne and regional Victoria.
Reactive Clay Soils
Common throughout Melbourne's western and northern suburbs. These soils shrink and swell with moisture changes, requiring specialized foundation design to prevent cracking and structural movement.
Silurian Mudstone
Predominant in Melbourne's eastern suburbs, this weathered rock provides generally stable bearing conditions but requires careful assessment for excavation and drainage considerations.
Sandy Soils
Found in coastal areas and river terraces, offering good bearing capacity but requiring assessment for drainage and potential erosion issues.

Frequently Asked Questions
Why do I need a soil test for my new home?
A soil test is legally required under Australian building codes for all new residential construction. The test determines what type of earth your house will be built on, to enure it remain intact through out its life.
Without a proper soil test, you can't get a building permit, and your structural engineer can't design safe foundations for your home.
How much does residential soil testing cost?
Residential soil testing in Melbourne typically costs between $1,800-$3,500 depending on your site size, access conditions, and soil complexity. This represents less than 1% of your total building cost.
The investment in proper soil testing can save you thousands in potential problems later, making it one of the most cost-effective parts of your building process.
How long does the soil testing process take?
The on-site drilling typically takes 1-2 days for a standard residential block. Laboratory testing takes 3-5 business days, and report preparation takes another 2-3 days.
What is AS2870 and why is it important?
AS2870 is the Australian Standard that sets out how to classify building sites based on soil conditions. It creates a simple system (Class A through E) that tells builders what type of foundation your home needs to be safe.
This classification system ensures your foundation is designed correctly for your specific soil conditions, preventing costly problems like cracking walls, uneven floors, and foundation failure.
Can I build without a soil test?
Building without a soil test is illegal under Australian building regulations. Council won't issue a building permit without a compliant geotechnical report, and your builder's insurance may be void.
More importantly, building without understanding your soil conditions puts your investment at serious risk of structural problems that can cost tens of thousands to repair.
What happens if my soil is reactive clay?
Reactive clay soils are common in Melbourne and shrink and swell with ground water changes. This doesn't mean you can't build - it just means your foundation needs special design features to handle the movement.
Solutions include waffle pod slabs, deeper footings, or pier and beam systems. Your structural engineer will use our soil report to design the most effective foundation for your specific conditions.
Do I need soil testing for home extensions?
Most home extensions require soil testing, especially for significant additions like second stories or large ground floor extensions. The requirements depend on your local council and the extension size.
We also assess how your new extension foundations will connect with existing foundations to ensure structural compatibility and prevent differential movement.
What's included in your soil test report?
Our comprehensive report includes AS2870 site classification, soil profile description, laboratory test results, foundation design recommendations, and specific construction guidelines.
The report is formatted and includes everything your structural engineer needs to design safe, cost-effective foundations.
Are you NATA accredited and insured?
Yes, all laboratories and testing is conducted in NATA-accredited facilities, which ensures the highest quality and accuracy.
This accreditation and insurance gives you confidence that our reports will be accepted by councils, engineers, and building surveyors throughout Victoria.
What if I have a sloping block?
Sloping blocks require special consideration for cut and fill earthworks, retaining walls, and drainage. We assess slope stability and provide recommendations for safe construction on sloping sites.
Our report will include specific guidelines for excavation, retaining wall design, and stormwater management to ensure your sloping block is developed safely and cost-effectively.
When should I order my soil test?
Order your soil test after finalising your home's position on your block with qualified professionals. This ensures the test locations match your final building footprint and foundation design requirements.
Many builders recommend completing soil testing during the preliminary design phase, giving your architect and engineer time to incorporate the findings into the most cost-effective design solution.
Do you provide footing inspections?
Yes, we provide professional footing inspections to verify that your excavated foundations match our soil report recommendations. This inspection is typically required by your building surveyor before concrete pouring.
Our qualified engineers check excavation depths, bearing surface quality, and compliance with foundation design specifications, providing written certification for your building approval process.
