Product Overview

Summary: This Safe Operating Procedure sets out a clear, repeatable method for planning, installing and inspecting control joints to manage cracking, structural performance and site safety. It helps Australian construction businesses achieve compliant, high-quality finishes while protecting workers and the public from hazards associated with cutting, forming and treating control joints.

Control joints are critical to the long-term performance and safety of concrete slabs, pavements, masonry and wall systems, yet they are often inconsistently detailed, installed or inspected on Australian worksites. Poorly implemented control joints can lead to uncontrolled cracking, trip hazards, water ingress, structural deterioration and costly remedial works. This Control Joint Implementation Safe Operating Procedure provides a structured, end-to-end process covering design intent, layout, cutting or forming methods, joint preparation, sealing and verification, ensuring that joints perform as intended throughout the asset life cycle.

Developed specifically for Australian construction and maintenance environments, this SOP aligns with WHS obligations and relevant Australian Standards to address both build quality and on-site safety. It guides your team through pre-start planning, plant and equipment controls (including saw cutting and dust management), interface with other trades, and documentation requirements. By standardising the way control joints are implemented across projects, businesses can reduce defects, minimise rework, and demonstrate due diligence in the event of an incident, inspection or warranty claim.

Key Benefits

• Ensure consistent, code-aligned implementation of control joints across all projects.
• Reduce structural defects, uncontrolled cracking and long-term maintenance costs.
• Minimise worker exposure to dust, noise and cutting equipment hazards during joint installation.
• Streamline communication between designers, site teams and subcontractors regarding joint locations and details.
• Improve documentation and traceability to support WHS compliance, inspections and warranty claims.
