Drilling Equipment for Hard Ground
Hard rock drilling isn’t just about brute force—it’s about working smart. Our crew uses purpose-built rigs, drill bits and mud systems designed for fractured, abrasive or high-pressure ground.
We also monitor drilling conditions in real time, adapting techniques as needed to reduce equipment wear and avoid delays. From water access bores to test holes for geological studies, we’re committed to delivering consistent performance in even the most challenging environments.
With a strong focus on safety, precision and job planning, we take the guesswork out of difficult drilling. If your jobsite sits on stubborn ground, we’re ready to take it on. Let’s talk about how we can help.
Frequently Asked Questions
What equipment is needed for hard rock drilling?
Hard rock drilling requires specialised rotary or down-the-hole (DTH) drilling rigs equipped with heavy-duty drill bits, such as tungsten or diamond-tipped tools. Additional components like drill mud systems, casing and compressors are often used to support borehole stability and improve penetration through dense or fractured rock layers.
How long does hard rock drilling take?
The duration depends on the rock type, depth required and site conditions. Drilling through dense or fractured rock takes longer than soft ground due to slower penetration rates and increased tool wear. Jobs may take anywhere from a few hours to several days based on scope and complexity.
Can you drill through granite or basalt?
Yes, granite, basalt and other dense rocks can be drilled using appropriate techniques and equipment. Rotary and percussion methods are commonly used to penetrate hard rock effectively, although the process requires more power, specialised tooling and experienced operators compared to standard soil drilling.
