Rock Cutting Service

Onyx Engineering offers precise rock cutting services for quarrying, site preparation, tunnel refurbishment, and geological or civil works. Using advanced cutting equipment and safe, controlled procedures, we enable rapid rock segmentation with minimal vibration, dust, and disruption to surrounding operations.

Why choose Onyx for rock cutting

• Precision and control: High-accuracy cuts guided by project tolerances and interfaces with utilities, structures, and safety zones.
• Safety and compliance: ISO 45001:2018 health & safety management and ISO 9001:2015 quality management, with site-specific RAMS and permits.
• Versatility across rock types: Effective on granites, limestones, sandstones, and metamorphic rocks, plus engineered rock masses with inclusions.
• Reduced disruption: Dust suppression, water-blast management, and vibration control to protect adjacent work and environments.
• Resource recovery and planning: Cut plans optimized for material recovery, waste minimization, and downstream processing.

Our rock cutting capabilities

• Segmentation cuts: Precisely separated rock blocks for extraction, stabilization, or relocation.
• Linear and contour cuts: Custom profiles for tunnels, retaining walls, or excavation boundaries.
• Chamfering and bevel cuts: Preparation for joints, interfaces, or decorative/architectural detailing.
• Pilot holes and core drilling: Pre-cutting guidance for heavy removal or dynamic cutting sequences.
• In-situ rock profiling: Acoustic/seismic or visual assessment to refine cutting strategy and safety planning.

Methods and equipment

• Equipment: Diamond wire saws, wire saws, heavy-duty chain saws, hydraulic splitter systems, and precision rock cutters.
• Techniques: Wet cutting for dust control, dry cutting when appropriate, controlled worming and cooling, and vibration-minimized operations.
• Quality controls: Cut depth verification, surface finish checks, and debris containment for clean handovers.

Health, safety, and environment

• Permitting and regulatory alignment: Compliance with local mining, construction, and environmental permits.
• Dust and noise control: Water suppression, enclosures, and vibration monitoring for sensitive areas.
• Safe handling: Lockout/tagout for nearby utilities, PPE, and site-specific RAMS.
• Training: Operator proficiency, toolbox talks, and hazard identifications.

Applications

• Quarry redevelopment or rock mass excavation
• Tunneling support and modernization work
• Foundation and strata preparation for civil/industrial projects
• Architectural rock features and sculpting
• Rehabilitation of historic or geotechnically sensitive sites
