High Speed Rotary Core Drill Mast: Unlocking Accurate Data in Challenging Terrain

Geovert’s High Speed Rotary Core Drill Mast delivers reliable geotechnical and environmental data in even the most challenging terrain, providing the foundation for safe and efficient design.

Why Core Drilling Matters

Every geotechnical or environmental project starts with one key question: what lies beneath? Without reliable subsurface data, designers and contractors are forced to make assumptions about soil and rock conditions. These assumptions often lead to overdesign, unexpected delays, or costly remedial works when conditions don’t match expectations. Core drilling provides the most accurate and continuous record of ground conditions, producing samples that allow engineers to measure strength, weathering, and groundwater characteristics.


Yet in many projects, collecting that data is not straightforward. Steep slopes, remote valleys, and confined corridors often prevent the use of conventional drill rigs. Recognising this, Geovert developed a High Speed Rotary Core Drill Mast specifically designed to overcome access constraints while maintaining sample quality.

Engineering for Versatility and Efficiency

At the heart of the mast is a hydraulic high-speed drill head capable of HQ coring. This ensures samples remain intact and of laboratory quality, providing engineers with reliable data on strength, structure, and composition. Unlike rigs limited to one base platform, the mast can be mounted interchangeably on excavators, crawlers, or wagons, giving project teams flexibility to adapt to site conditions.


This versatility translates into measurable efficiency. A single rig can be redeployed across multiple phases of work, from geotechnical site investigations to test anchor installations and even down-the-hole (DTH) drilling. Mobilisation costs are reduced, while equipment utilisation is maximised - benefits that flow directly to clients in both time and budget savings.


Accessing the Inaccessible

Where the High Speed Rotary Core Drill Mast truly distinguishes itself is in its compatibility with rope access techniques. Geovert’s specialist crews are trained to position and operate the mast on near-vertical slopes, riverbanks, and confined transport corridors where no conventional rig could operate.


Consider a highway realignment in steep terrain. Traditional access tracks might require significant earthworks, vegetation clearance, and safety barriers before a rig can be mobilised - works that increase both cost and environmental impact. By contrast, a rope access approach allows the mast to be positioned directly at the face, reducing disturbance and enabling core recovery exactly where it is needed.


Meeting the Demands of Modern Projects

Infrastructure development, mining operations, and natural hazard mitigation all rely on accurate ground models. In regions prone to landslides, earthquakes, or weather extremes, the cost of inaccurate data is magnified. The High Speed Rotary Core Drill Mast was designed with this in mind, offering:


  • All-terrain capability, ensuring reliable operation in diverse geology

  • High-speed rotary performance, reducing drilling time and increasing productivity

  • Multi-functional use, supporting both investigative and construction-phase drilling


The system’s ability to integrate investigative coring with construction support makes it particularly valuable for projects where time is critical.


Building Confidence Through Better Data

Ultimately, the High-Speed Rotary Core Drill Mast embodies Geovert’s philosophy: combining innovative technology with access expertise to solve problems others cannot. It delivers high-quality geotechnical and environmental samples in any terrain, enabling engineers to design with confidence and clients to proceed with clarity.
