NexPand Use Technical Training: Safe, Controlled Rock Breaking with Harlen Supplies

Efficient rock breaking is not achieved by product alone. It depends on correct preparation, correct mixing, and disciplined on-site execution. At Harlen Supplies, we understand that when NexPand, our trusted expansive mortar, also known as a rock breaking chemical, is used correctly, it solves real problems: unsafe blasting conditions, production delays, structural risk, noise and vibration constraints, and damage to surrounding infrastructure and environments. That is why we don’t just supply NexPand. We train your team to use it properly.

Why Training Matters

NexPand is a highly effective controlled rock breaking solution, but it is not a guessing game. Incorrect hole sizing, spacing, burden, mixing ratios, temperature management, or placement can lead to poor results, safety concerns, and unnecessary cost. Our training is designed to prevent that. We bridge the gap between “product received” and “problem solved” by giving teams the technical understanding and practical confidence to apply NexPand safely, consistently, and efficiently across real-world conditions.

What Our NexPand Training Covers

Our NexPand training offering is structured, practical, and aligned with industry standards. Each session is facilitated by experienced practitioners with direct field exposure in mining, quarrying, and construction environments.

Key focus areas include:

• Product understanding

  Composition, characteristics, behaviour, and realistic performance expectations for NexPand in different rock types and conditions.

  
  

• Correct application

  Hole diameter, pattern, spacing, burden, depth, and volume calculations for specific tasks; from trenching and boulder breaking to sensitive infrastructure work and restricted blasting environments.

  
  

• Mixing and placement

  Accurate water ratios, mixing discipline, temperature considerations, pour techniques, and curing times to ensure controlled, predictable results.

  
  

• Operational integration

  How NexPand fits into existing workflows, project planning, scheduling, and equipment use to minimise downtime and improve overall productivity.

  
  

• Risk control and compliance

  Safe handling, PPE requirements, storage, supervision, and alignment with site rules and regulatory guidelines.

Training is delivered in a clear and practical format. We focus on what your operators, supervisors, and safety personnel need to know to get the job done safely and correctly.

On-Site Practical Support

Where feasible and on request, we provide on-site practical training and assistance, allowing teams to apply NexPand under real operating conditions.

This is where theory becomes measurable value:

• Your team drills, mixes, and applies NexPand on an active or simulated job.

• Our technical specialist is present to guide decisions, correct errors, and transfer practical knowledge.

• You leave with an approach tailored to your ground conditions, equipment, and production targets.

This reduces trial-and-error, limits avoidable failures, and supports safer, cleaner, and more predictable rock breaking.

Certification and Acknowledgement

On completion of the NexPand training:

• Participants receive a Certificate of Attendance, demonstrating that they have been trained on the safe and effective use of NexPand.

  
  

• Each attendee signs an Acknowledgement Form, confirming their understanding of:

  • NexPand handling and application requirements

  • The importance of adhering to recommended procedures

  • The obligation to follow internal and regulatory safety protocols

    
    

This is not a box-ticking exercise. It forms part of a documented framework of responsibility and due diligence for both the client and Harlen Supplies.

HIRA, Responsibility, and Safe Practice

Before NexPand is used on any site, a Hazard Identification and Risk Assessment (HIRA) is essential. Our message is simple and firm:

• NexPand must be used within a structured risk-managed environment.

• Failure to follow the technical guidelines, safety instructions, and HIRA processes can result in poor performance or unsafe conditions.

• Harlen Supplies’ commitment is to provide the knowledge, support, and documentation needed to help clients operate responsibly.

  
  

We engage with supervisors, safety officers, and management to ensure NexPand is integrated into site procedures, not used in isolation or on assumption.

Our Commitment

Harlen Supplies integrates NexPand training into every stage of rock breaking support, ensuring teams work safely, accurately, and in line with site responsibilities. For operations that prioritise control, compliance, and consistent technical outcomes, our experts are available to train your people to the required standard.
