About Us
Geotechnical Drilling Specialists:
Greater Sydney & NSW Region
TerraForma Drilling is a geotechnical drilling contractor based in Sydney, NSW. We work with engineers, consultants, developers, and local councils, providing investigation drilling, SPT and DCP testing, environmental drilling, and monitoring bore installation.
Our rig is a ute-mounted solid flight auger. That means we can get into places bigger rigs can't, such as tight suburban sites, sloped blocks, low clearance, you name it. It still does the job properly, just without all the access headaches.
We're set up to meet Tier 1 project requirements. Our rig has full hydraulic interlocks and safety systems, follows a documented service schedule, and complete service records are available if you need them. Whether you're doing a single-site investigation or a multi-location program, we operate to the standard your project demands.
Certifications
Our operations are independently audited and certified to ISO 9001, ISO 14001, and ISO 45001 standards.

We followed strict sampling protocols with no delays. The consultant collected all required samples and kept the assessment on schedule.
Monitoring Bore Installation
We installed bores to the exact depth, screen, and casing specifications, making them ready for immediate use by the project team.
Multi-Site Drilling Programme
We managed multiple sites with varying conditions, ensuring consistent drilling and safety practices across all locations.
Shallow Pavement Investigation
With tight access, hardstand surfaces, and no space for larger equipment, we completed the investigation efficiently without over-mobilising.
