Core Barrel Drilling

Specialist Drilling Sevices Victoria

Core barrel drilling is the ideal method for penetrating hard rock and challenging ground conditions where standard augers can’t perform. Our specialised core barrels are engineered to cut clean, precise holes while maintaining structural integrity around the bore, making them perfect for commercial, civil, and infrastructure projects.
At EDC Australia, we use high performance core barrels and rock cutting teeth designed for efficient cutting, reduced resistance, and reliable performance across all rock types. This method allows for faster drilling, improved accuracy, and cleaner results - even in dense, abrasive, or mixed formations.

Whether you’re preparing foundations, installing piers, or working on complex drilling sites, our experienced operators deliver safe, consistent, and cost effective outcomes. We tailor our approach to your project requirements, ensuring the right barrel size, and drilling method for every job.

  • Versatile Applications Suitable for residential, commercial, and large-scale infrastructure drilling needs.
  • Precision & Safety Expert operators ensure precise drilling while maintaining strict safety and regulatory standards.
  • Advanced Equipment Heavy-duty drilling equipment capable of handling a wide range of soil and rock conditions.
  • Reliable Project Delivery Timely, professional service with minimal disruption and expert guidance throughout the process.

We use industry best practices and customised equipment for drilling basalt efficiently with our owned and operated machinery:

  • Equipment selection: EDC Australia has a large range of heavy-duty, custom-made core barrels and rock drills designed for all hard rock applications. Our experienced operators ensure the correct equipment and methods are applied to achieve best results.
  • Tungsten carbide rock teeth: EDC Australia uses only premium tungsten carbide rock teeth that resist wear and maintain sharpness when cutting through hard, dense rock.
  • Proper drilling speed and pressure: Using the correct down force and rotation speed for the conditions, ensures that the equipment can continue to cut the rock efficiently.
  • Use of Water: Cooling and lubricating the drill can reduce friction, remove cuttings, and limits heat buildup. This also reduces environmental impact from dust.
  • Pre-drilling or pilot holes: Depending on the site-specific conditions, pre drilling pilot holes can be effective for drilling larger diameter bored piers.
  • Regular maintenance: EDC Australia completes all maintenance and repair works inhouse to minimise downtime; ensuring a reliable service to their customers

    • Following these practices helps maximize efficiency, extend equipment life, and provide a quality and stress-free drilling service - with a strong focus on delivering value for money.

Sedimentary

  • Sedimentary rocks are made when small pieces of minerals or plants build up and get pressed together over time. They often form in layers called strata. Common examples are sandstone, limestone, mudstone, siltstone and shale.

Igneous

  • Igneous rocks form volcanic activity when hot, melted rock called magma or lava cools and hardens. If it cools slowly underground, large crystals form, like in some types of granite. If it cools quickly on the surface, the crystals are small, like in basalt.

Auger

  • An auger is a drilling tool used on machinery to bore holes into the ground. It features a spiral-shaped blade that rotates to lift soil out as it drills. Augers can be custom made to suit a variety of ground conditions ranging from sand and clays and to hard rock.

Core Barrel

  • A core barrel is designed specifically for drilling for hard / dense rock. It is engineered to cut by grinding in a precise circular path, while resulting in the extraction of a solid cylindrical core.
