Rotary Core Drilling for Geotechnical Investigations
What Is Rotary Core Drilling?
Rotary Core Drilling, also known as Diamond Core Drilling, is one of the most effective methods for collecting continuous rock and soil samples during geotechnical site investigations. At Rivicore, we specialise in high-quality rotary core drilling using both split tube and triple tube core barrels, therefore ensuring precise, reliable samples in every project. In addition, our methods are carefully tailored to suit varying ground conditions and specific project requirements.You can read more about types of drilling here
How the Rotary Core Drilling Method Works
The key to this method lies in the diamond-tipped drill bit, engineered to cut through hard rock with precision. These bits are embedded with industrial-grade diamonds set in a metallic matrix and designed to withstand the demands of different geological formations.
As the bit rotates, water or drilling fluid is injected to cool the bit; consequently, friction is reduced, and cuttings are flushed out of the borehole, thereby improving drilling efficiency and reducing wear.
Core Barrel Systems
For geotechnical applications, we use a triple tube and double split tube core barrel system that allows for the recovery of high-quality, undisturbed core samples. In addition, this system includes an inner liner that protects the sample during extraction, ensuring that core orientation remains accurate and disturbance minimal—especially valuable when working with softer or fractured formations.
Why Choose Rivicore for Rotary Core Drilling
Moreover, our team has experience across a wide range of geological environments, and we adapt our drilling techniques and equipment to maximise core recovery, even in difficult conditions. Whether you’re investigating foundation conditions, slope stability, or planning infrastructure development, our drilling services therefore provide reliable, detailed subsurface information to guide your engineering decisions.
Rotary Core Drilling offers a number of significant advantages over conventional drilling. Cutting is more accurate than percussive techniques which means that there is less chance of damage which could affect structural integrity. Rotary Core Drilling requires less space and head room than other drilling methods.
Rotary Core Drilling has many uses and applications such as:
- Drilling for Foundation Purposes
- Underground Water Monitoring
- Pile Integrity
- Pile Contact Point
- Shallow Mineral Exploration
- Dam Wall Integrity
- Bridge Investigations
- Road Maintenance
