Geotechnical Drilling Specialists
Across NSW
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.

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.
