• Quality assurance: ISO 9001:2015-certified processes ensure accurate cuts, clean interfaces, and thorough QA/QC inspections.
• Technical expertise: Skilled crews with experience in reinforced concrete, post-tensioned slabs, utility corridors, and architectural finishing requirements.
• Minimal disruption: Specialized equipment and methodologies designed to limit dust, noise, and vibration to surrounding areas.
• Waste and recycling focus: Containment and dust suppression paired with responsible waste handling and material reuse where feasible.

Our concrete cutting capabilities

• Wedge and saw cutting: Straight, accurate cuts in walls, slabs, and cores for controlled demolitions or renovations.
• Controlled demolition cuts: Targeted removals to create openings, penetration points, or utility access without compromising structural elements.
• Grooving and joint cuts: Isolation joints, expansion joints, and crack control cuts for future renovations or deconstruction sequences.
• Coring and penetrations: Core drilling for mechanical, electrical, and plumbing penetrations with clean finishes.
• Roadway and curbing cuts: Precise asphalt and concrete cut operations for roadways, sidewalks, and curbs with minimal disruption.
• Access and tie-ins: Cutting around embedded equipment or utilities to enable safe removal or relocation.

Methods and equipment

• Equipment: Diamond blade saws, wire saws, ring saws, wall sawing, track-mounted systems, and wire sawing for deeper or larger sections.
• Techniques: Wet and dry cutting as appropriate, dust suppression, and vibration-minimized approaches for sensitive sites.
• Quality controls: Depth verification, finish cleanliness, and debris containment to support fast handovers.

Health, safety, and environment

• Regs and compliance: Adhere to local permit requirements, environmental controls, and waste management guidelines.
• Dust and noise control: Enclosures, misting, and containment to protect occupants and adjacent work areas.
• Safe handling: Lockout/Tagout coordination for utilities, PPE standards, and site-specific RAMS.
• Training: Ongoing operator training, toolbox talks, and hazard identifications.

Applications

• Building renovations and retrofits
• Decommissioning and asset relocation
• Structural openings for mechanical, electrical, and plumbing
• Basement and utility access cuts
• Concrete repairs and overlay preparation
