Foundation Drilling

Specialist Drilling Sevices Victoria

Foundation drilling is the critical first step in creating stable, long lasting structural support for commercial, civil, and residential projects. At EDC Australia, we specialise in precision foundation drilling across Australia, delivering clean, accurate boreholes suited for piers, footings, retaining walls, and deep foundation systems. Our experienced operators use advanced drilling equipment designed to perform in all ground conditions - from soft soils to dense rock.

We ensure every bore is drilled to the correct depth, diameter, and alignment, providing a reliable base for structural loads and engineered designs. Whether you’re preparing for new construction, infrastructure upgrades, or complex geotechnical works, we offer safe, efficient, and cost-effective foundation drilling services. Every project is completed with strict attention to accuracy, site safety, and environmental standards.

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.
