Rock Bolts and Netting
What are Rock Bolts and Netting?
Rock bolts are long anchors that are commonly used alongside wire fall-arrest netting. Typically installed into pre-drilled bore holes and grouted into place, rock bolts are usually installed on a grid and transfer loads from an unstable face into a load-bearing solid rock. They are also used in conjunction with surface retention methods, such as wire mesh or shotcrete.
Wire fall-arrest netting is safety netting used to catch and absorb the impact of falling objects, providing a significant barrier to catch falling debris and waste materials.
Rock bolts are commonly used to enhance the stability and load-bearing capacity of rock masses. They can also be utilised for structural repairs of retaining walls, bridge walls, and tunnels. You may encounter rock bolts in various infrastructure projects, such as railway and highway developments.
Advantages of Rock Bolts and Netting
Rock bolts and netting are fast and easy to install, using lightweight equipment to create an efficient, cost-effective process. High tensile strength is achieved almost immediately upon installation, providing instant support and greatly enhancing safety and stability.
The netting is flexible enough to match existing slopes and rock profiles, maximising the effectiveness of the installation. The netting does not inhibit vegetation regrowth, making it a practical, environmentally responsible choice for ongoing site management.
Sectors We Support
We deliver rock bolt and netting solutions across a wide range of sectors where ground stability, slope retention and safe access are essential. Our experience includes projects within:
- Infrastructure – Stabilising cuttings, embankments and retaining structures for highways, public spaces and large civil engineering schemes.
- Energy – Supporting safe excavation and access across power generation, renewable sites and utility infrastructure.
- Marine – Reinforcing rock faces, sea defences and coastal structures exposed to erosion and challenging conditions.
- Rail – Securing rail cuttings, tunnels and embankments to maintain safe, uninterrupted operations.
- Residential – Supporting sloped development sites, landscaped features and retaining walls.
- Culture & Institution – Providing stability solutions for heritage sites, public buildings and specialist architectural environments.
Whether you need work on infrastructure, energy, rail, or cultural and institutional projects, we offer a complete service, backed by years of experience, unmatched technical expertise, and exceptional project execution.

Precision Installation With Advanced Drilling and Rig Equipment
Rock bolts are installed into pre-drilled boreholes formed with rotary and percussive rigs and down-the-hole hammers, depending on ground conditions. Rock bolts and netting can be installed using excavator machines or drilling rigs.
We invest in advanced machinery to ensure precision and reliability across every project – even in challenging ground conditions. Our machinery is meticulously maintained to reduce downtime and enhance productivity, allowing us to meet tight deadlines.
We utilise drilling tools and equipment to create bored piles while maintaining high safety and environmental standards. Whether bored piles are required for bridges, buildings, or retaining walls, our equipment ensures maximum efficiency and minimal disruption to the area.
