Tight-Access SPT Investigation
We supported a geotechnical investigation that required a compact drilling solution due to limited site access.
Standard Penetration Testing (SPT) Services in Sydney & NSW
TerraForma Drilling offers Standard Penetration Testing (SPT) services across Greater Sydney and regional NSW. We support geotechnical investigations, site classifications, and foundation assessments with calibrated equipment and a custom ute-mounted drilling platform designed for tight-access sites.
Our Process
What is Standard Penetration Testing (SPT)?
The Standard Penetration Test (SPT) is a common on-site method for testing soil. It measures soil resistance by counting the number of hammer blows required to drive a sampler into the ground. The resulting SPT N-values help engineers assess foundation design, site classification, and ground conditions.
While both Standard Penetration Testing (SPT) and Cone Penetration Testing (CPT) are used for geotechnical site investigations, SPT is commonly selected where borehole drilling, soil sampling, and direct subsurface information are required. Geotechnical engineers choose the appropriate testing method based on ground conditions, investigation objectives, and project requirements. Standard Penetration Testing is often used in Sydney and NSW before residential, commercial, infrastructure, or environmental projects begin. TerraForma uses calibrated equipment and a small drilling platform to reach places where larger rigs cannot.

Sampling & Testing Methods
SPT Data & Testing Capabilities
SPT N-Value Data
Our calibrated Standard Penetration Testing gives N-value data that engineers use to assess soil strength, density, and subsurface conditions.
Field Records & Borehole Information
We provide SPT N-value data, borehole records, and field observations in a clear and organised format to support engineering assessment and project documentation.
Testing to Your Investigation Requirements
We conduct SPT testing at the depths and intervals you specify, in accordance with your project requirements and bore plans.
Tight-Access SPT Investigations
Our small ute-mounted drilling platform allows Standard Penetration Testing in Sydney locations where larger rigs cannot reach.
How It Works
From Scope to Site Mobilisation
01
Submit Your Scope
Send us your bore plan, required SPT test intervals, investigation depths, and site access details so we can accurately scope your project.
02
Receive a Quote
We review your investigation requirements, provide a clear commercial proposal, and complete Dial Before You Dig (DBYD) enquiries before mobilisation as part of our commitment to safe field operations.
03
Mobilisation & SPT Field Testing
Our drilling team mobilises to your Sydney or NSW site and performs Standard Penetration Testing in accordance with your investigation plan and testing requirements.
WHY CHOOSE US
Why Choose TerraForma Drilling?
Calibrated SPT Equipment
Our calibrated SPT testing equipment provides reliable field data for geotechnical investigations across Greater Sydney and regional NSW. Calibration records are available on request before the first engagement.
Tight-Access SPT Capability
Our custom ute-mounted drilling platform allows SPT testing on Sydney sites where standard rigs cannot operate, including narrow residential lots, low-clearance structures, and confined corridors across Greater Sydney.
Drilling by Engineers, for Engineers
We know how important Standard Penetration Test data is for engineering decisions. That’s why we align our testing with your investigation goals and project needs.
Fast Sydney Mobilisation
We can mobilise within 24 hours across Greater Sydney and offer quick support throughout NSW to help keep your investigation projects on track.
Certified Quality & Safety Systems
We use ISO-certified management systems, follow maintenance schedules, and provide WHS documentation to support compliant project delivery across Greater Sydney and regional NSW.
Transparent Field Records
Every SPT test is documented with depth, blow count, N-value, and soil description recorded at the time of testing. Field records are handed directly to your nominated engineer or consultant on completion — no delays, no chasing.
