Rock Bolting
Rock bolting is essential for maintaining the integrity and stability of a rock or cliff face
Rock bolting is a proven method for reinforcing unstable rock formations and ensuring long-term structural stability from steep road cuttings to underground tunnels and mining sites. At Ground Stabilisation Systems (GSS), we deliver tailored rock bolting solutions across Australia, helping to protect infrastructure, control movement in fractured rock, and support complex excavation projects.
Our experienced professionals use advanced drilling technology and specialist equipment to install high-quality rock bolts into weak or unstable rock masses. These bolts anchor the load from loose surface layers to the more secure, intact surrounding rock below.
Whether stabilising a slope, supporting a tunnel wall, or protecting a rail cutting, rock bolts are critical components of many ground support systems. We work across a wide range of sectors, including mining, civil construction, infrastructure, and geotechnical remediation. By securing fractured rock and minimising the risk of dislodgement, our rock bolting services help keep people, assets, and worksites safe.
Each project begins with a detailed assessment of the site conditions and rock mass. Our staff determine the most effective locations to drill — usually between 45mm and 150mm in diameter — and selects the ideal rock bolt applications based on ground composition, load requirements, and installation depth.
We use both mechanical and grouted systems, including expansion shell bolts, fibre-reinforced polymers, and cement grouting, to secure each bolt in place. Depending on the rock type and performance goals, we may also install cable bolts for deeper or more complex conditions.
The rock bolting process involves drilling into the rock face to create a hole where the bolt will be anchored. Once inserted into the drilled hole, the rock bolt is either mechanically fastened or grouted along its whole length to ensure it is securely bonded to the rock. The result is a reinforced structure that resists movement, supports loads, and binds loose layers together.
Rock bolts transfer tension from potentially unstable or loose rock mass on the surface to stronger, load-bearing rock beneath. This helps to stabilise the overall formation and prevent rockfalls, cracking, or collapse.
Typical applications include:
GSS has decades of hands-on experience delivering safe, reliable, and efficient rock bolting services across some of Australia’s most challenging environments. We understand how critical it is to use the right bolts, techniques, and installation methods to ensure the long-term performance of your project.
Our expert team uses the latest equipment, including remote controlled drilling systems, and works closely with Geotechnical engineers and site managers to design and implement effective ground support strategies. Whether dealing with a high-risk excavation, a complex slope, or underground works, GSS provides complete peace of mind with fully engineered solutions.
We install high-quality rock bolts in accordance with Australian standards, always focusing on safety, performance, and durability. With diverse experience in mining, transport, construction, and maintenance, we’re trusted to deliver rock bolting projects on time, on budget, and to the highest standards—even in remote or difficult-access locations.When securing your site, trust the team that understands rock from the inside and out.

Where is rock bolting commonly used?
Rock bolting has diverse applications across industries, including civil construction, tunnelling, mining, and infrastructure. It is commonly used to stabilise portions of rock cuttings, tunnel walls, slopes, and bridge foundations—any situation where fractured or unstable rock poses a risk to safety or structural integrity.
What are the common types of rock bolts?
Common types of rock bolts include mechanical bolts (with expansion shells), grouted bolts (cement or resin), and cable bolts for deeper or more complex rock formations. The best type depends on ground conditions, rock quality, and the project’s performance requirements.
Why is rock bolting preferred over other stabilisation methods?
Rock bolting offers a cost-effective and highly adaptable solution for stabilising unstable exterior rock masses in various conditions. It works well with other systems like meshing or shotcrete, and can be installed quickly with minimal disruption to the surrounding environment.
