The Northern Rivers Geotechnical Drilling
Understanding what’s happening below the surface is critical before any major build begins. That’s why North Coast Drilling & Wicks provides professional geotechnical drilling services across the Northern Rivers, helping engineers, planners and construction teams gather reliable subsurface data.
From identifying soil types to locating groundwater and testing load-bearing capacity, our work provides the insights needed for safe, informed project decisions. We use a range of sampling and drilling methods—adjusted to suit each site’s conditions—and offer end-to-end support from fieldwork to reporting. Our geotechnical services often work in tandem with piezometer installation, drilling rigs, and ground improvement strategies to ensure thorough, practical outcomes.
With over 32 years of on-the-ground experience and the right equipment for the job, we deliver accurate results with a safety-first approach. For expert geotechnical drilling in the Northern Rivers, call
0401 380 986 and talk to our team today.

Frequently Asked Questions
What does a geotechnical drilling contractor do?
A geotechnical drilling contractor specialises in drilling boreholes and collecting soil and rock samples to assess subsurface conditions. These investigations provide critical data for engineers to design foundations, earthworks and other structures safely. Contractors may also install monitoring instruments like piezometers and inclinometers to observe soil and groundwater behaviour over time. Services include standard penetration tests (SPT), cone penetration tests (CPT) and other in-situ tests to evaluate soil strength, density and composition. Geotechnical drilling is essential for construction, infrastructure development and environmental assessments, ensuring that designs are based on accurate subsurface information and that potential risks like settlement or slope instability are managed.
What equipment do geotechnical drilling contractors use?
Geotechnical drilling contractors use a range of specialised equipment tailored to site conditions and project requirements. Common rigs include auger rigs for soft soils, rotary rigs for deeper boreholes, and sonic or percussion rigs for challenging conditions. Accessories include hollow-stem augers, casing pipes, drill rods and core barrels. Contractors also utilise sampling tools like Shelby tubes, split spoon samplers and standard penetration test (SPT) hammers. For in-situ testing, cone penetration testing (CPT) devices and vane shear testers are used. The selection of equipment depends on factors like drilling depth, soil type, access limitations and the specific testing or monitoring objectives.
Why is geotechnical drilling important for construction projects?
Geotechnical drilling is vital because it provides precise data about subsurface conditions, which directly impacts the design and safety of any construction project. By understanding soil and rock characteristics, engineers can identify potential hazards such as weak ground, high groundwater tables or expansive clays. This knowledge informs decisions on foundation type, depth, ground improvement requirements and other design elements, reducing the risk of structural failure or excessive settlement. Geotechnical drilling also supports compliance with local building codes and regulations, ensuring that projects are designed to meet safety standards and perform reliably over their intended lifespan.
