Tight-Access Residential Drilling
When larger rigs could not access the site, our ute-mounted SFA rig completed the full investigation without causing any disruption.
Solid Flight Auger Drilling in Sydney & NSW
TerraForma Drilling provides Solid Flight Auger drilling in Sydney for geotechnical and environmental investigations. Our purpose-built ute-mounted drilling rig delivers efficient drilling, sampling, and testing on tight-access sites across Sydney and regional NSW.
Our Process
What is Solid Flight Auger Drilling?
Solid Flight Auger (SFA) is a drilling method using a continuous helical auger to advance a borehole and recover soil samples for site investigation. It is widely used for geotechnical investigations, environmental assessments, foundation design, and subsurface profiling because it provides an efficient and reliable means of exploring ground conditions.
TerraForma's ute-mounted Solid Flight Auger rig bridges the gap between shallow testing platforms and larger tracked rigs. It offers the mobility needed for tight-access sites while retaining the capability for geotechnical investigations, sampling, and Standard Penetration Testing (SPT). As one of the top auger drilling contractors in Sydney, TerraForma keeps it all Quick and Reliable.

FAQs
Common Questions
Solid Flight Auger drilling is commonly used for geotechnical, environmental, and site investigations. It allows engineers and consultants to collect soil samples, assess subsurface conditions, and obtain the ground information required for foundation design and project planning.
Yes. SFA drilling can be performed using compact rigs that are specifically designed for restricted access environments, making it suitable for urban and confined locations.
Yes. Standard Penetration Testing (SPT) can be carried out as part of our geotechnical investigation services to assess subsurface soil conditions.
Mobilisation time depends on project scope and location, however we aim to respond quickly and efficiently to meet project requirements.
