Welcome to the newest addition to our fleet! One of the key features of our track-mounted drilling rig is its mobility. Equipped with tracks instead of wheels, this rig can traverse rugged terrains, including muddy, rocky, or uneven surfaces. The design allows it to easily access remote and challenging drilling sites. Being track-based provides a more stable platform, resulting in better hole alignment. Our track-mounted rig can reach depths of up to 250 meters in rugged terrain, while also reducing environmental impact due to its increased manoeuvrability, which leaves a smaller footprint.

Gold RC Drilling  in Shamva

 Reverse Circulation (RC) drilling ideally produces dry rock chips, as large air compressors dry out the rock ahead of the advancing drill. This method is one of the most popular for mineral exploration drilling.

 Reverse Circulation drilling uses rods with inner and outer tubes, allowing drill cuttings to return to the surface inside the rods. The drilling mechanism employs a pneumatic reciprocating piston, known as a hammer, which drives a tungsten-steel drill bit. Reverse circulation is achieved by blowing air down the annulus, creating differential pressure that the cuttings up the inner tube within each rod. This material reaches the deflector box at the top of the drill string, then moves through a sample hose attached to the top of the cyclone.

 Our cyclone is equipped with two sample boxes and a built-in splitter. The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom, where they are collected in a sample bag. For each drill hole, there will be a large number of sample bags, each marked to record the location and drilling depth from which the sample was obtained at 1 meter intervals . These sample bags are later taken for analysis to determine the mineral composition of the drilled hole. The analysis results for each individual bag represent the mineral composition at a specific sample point in the drill hole. Geologists can then review the ground analysis and make informed decisions about the value of the overall mineral deposit. Reverse Circulation drilling is one of the more cost-effective options for surface drilling. Generally, RC drilling is slower and more expensive than other methods like RAB but it achieves better sample recovery and has little to no cross contamination. It is also cheaper than Dimond (core sampling ) Drilling.

Is your borehole underperforming? Experiencing reduced water flow, silted screens, or discolored water? It may be time for deepening and flushing services in Zimbabwe, and Ragnarock Drilling is here to help.

What is Borehole Deepening?

Borehole deepening involves re-drilling an existing borehole to a greater depth. This technique:

• Expands the water storage zone
• Connects to deeper, more productive aquifers
• Boosts water yield significantly

Our expert guidance—often in collaboration with a qualified water diviner—ensures deepening targets zones with the highest potential.

What is Borehole Flushing?

Flushing entails circulating water or compressed air through the borehole to:

• Remove sediment, debris, and silt
• Restore purity and flow
• Extend borehole lifespan by preventing clogging

In Zimbabwe, borehole flushing is essential—especially when dealing with red soils or sandy formations where filters and screens are prone to clogging.

Benefits of Deepening & Flushing

1. Increased Water Yield Deepening taps into deeper layers, and flushing clears blockages—together, they maximize water production.
2. Improved Water Quality Flushing removes fine sediments and mineral deposits, leading to cleaner, clearer water.
3. Extended Borehole Longevity Regular maintenance reduces pump wear and prevents complete blockage.
4. Cost‑Effective Solution Revitalizing a borehole through deepening and flushing is often more affordable than drilling a new one.

Ragnarock Drilling’s Process

Here’s how we deliver reliable deepening and flushing services:

1. Assessment and Site Analysis We inspect current borehole performance, sediment levels, and geology using hydrogeological methods and water diviners where necessary.
2. Deepening The borehole is carefully extended into deeper aquifers using precision drilling rigs and techniques suited to the local ground conditions.
3. Flushing and Cleaning We use high-pressure water or compressed air to dislodge and evacuate sediments until the discharge runs clear.
4. Completion Testing We conduct capacity testing to measure improved yield and assess water clarity.
5. Pump Reinstallation Our team reinstalls or upgrades your pump system, optimizing it for the updated borehole specifications.

Are you planning to invest in a borehole for your home, farm, or business? Understanding the borehole drilling process in Zimbabwe can help you make informed decisions. At Ragnarock Drilling (Pvt) Ltd, we simplify the process and provide professional, efficient, and affordable borehole drilling services across the country.

In this post, we walk you through the step-by-step stages of drilling a borehole, so you know exactly what to expect when you work with us.

1. Site Survey and Hydrogeological Study

Before any drilling begins, our experts conduct a site survey to determine the best location for your borehole. This may include:

• Hydrogeological surveys to locate underground water sources
• Evaluating terrain and access routes
• Assessing environmental and legal considerations

This step is crucial for ensuring that drilling is successful and cost-effective.

2. Borehole Drilling

Once the site is approved, our team begins the actual drilling process using suitable techniques based on the ground formation:

• Mud rotary drilling
• Auger drilling
• Odex drilling
• Reverse circulation (RC) drilling (for deeper or more complex projects)

Our modern drilling rigs can handle any terrain across Zimbabwe with minimal disruption to the environment.

3. Borehole Casing and Installation

After reaching the required depth, we insert a borehole casing to stabilize the borehole walls and prevent collapse. This stage includes:

• Installing PVC or steel casing
• Gravel packing to filter sediments
• Sealing with bentonite or cement grout

This protects your water source and improves borehole longevity.

4. Borehole Development and Flushing

Next, we develop the borehole by cleaning out loose sediments and improving water inflow. This is done through:

• Air-lifting
• Jetting and surging
• Flushing using clean water

This step ensures your borehole delivers clean, sediment-free water.

5. Pump Installation and Testing

We install a submersible or bush pump, depending on your water needs and budget. This is followed by:

• Capacity (yield) testing to measure water flow rate
• Pump testing and calibration

We ensure your pump system is efficient, durable, and perfectly matched to your borehole specifications.

6. Final Inspection and Handover

Finally, we perform a full system inspection and provide you with:

• A completion report

At Ragnarock Drilling, we specialize in auger drilling, a highly effective technique for soil sampling, geotechnical investigations, and shallow borehole drilling. This guide explains how auger drilling works, its benefits, and its applications in construction and environmental projects.

What Is Auger Drilling?

Auger drilling is a rotary drilling method that uses a helical screw (auger) to bore into the ground and lift soil cuttings to the surface. It is best suited for:

• Soft to medium-density soils
• Clay and unconsolidated sediments
• Shallow-depth drilling (typically up to 100 feet)

Types of Auger Drilling

• Hollow Stem Auger Drilling – Allows for continuous soil sampling and tool insertion.
• Solid Stem Auger Drilling – Used for general drilling without sampling.

How Auger Drilling Works

1. Rig Setup – The drilling rig is positioned over the target location.
2. Auger Penetration – The rotating auger cuts into the ground, lifting soil through its helical flights.
3. Soil Extraction
   Hollow stem augers enable undisturbed soil sampling.
   Solid stem augers expel cuttings at the surface.
4. Depth Completion – Drilling continues until the desired depth is reached.

Key Benefits of Auger Drilling

• Cost-effective – Faster and more affordable than other drilling methods for shallow depths.
• Minimal site disturbance – Low environmental impact, ideal for urban and sensitive areas.
