Construction Product Offerings: Practical Solutions for Demanding Environments

On construction sites, performance is measured in control, safety, and continuity of work. Harlen Supplies aligns equipment, consumables, and expansive mortar rock-breaking solutions to these requirements, ensuring that drilling, cutting, breaking, and site management activities are carried out with reliable, predictable and technically appropriate tools rather than compromised by equipment limitations.

Sensitive Rock-Breaking & Demolition Solutions

Effective rock breaking is not only about force; it is about control, safety, and suitability for each specific environment and structure. We align the correct product to the specific requirement.

• NexPand Expansive Mortar:

  NexPand is our expansive mortar rock-breaking solution for controlled fracture of rock and reinforced concrete. It is suited to applications where blasting is restricted, vibration must be minimised, or adjacent structures and services require protection. Correctly drilled and prepared holes, combined with the expansive properties of NexPand, provide a precise, predictable break, reducing secondary breaking and improving safety on site.

  
  

• Kenella Forged Collar Drill Steel:

  For mechanical drilling operations, Kenella Forged Collar Drill Steel is available in carburised and non-carburised options to suit different wear, hardness, and impact profiles. These options allow operators to align tooling performance with ground conditions and drilling method, reducing downtime and unplanned tool failure.

  
  

• Kenella Knock-Off / Taper Drill Bits (32 mm–48 mm):

  Our Kenella Knock-Off/Taper Drill Bits in the 32 mm to 48 mm range are specified for compatibility, penetration efficiency, and bit life in demanding drilling environments. Matching bit design to steel, hammer, and rock conditions assists with straighter holes, improved advance rates, and reduced operating cost per metre drilled.

  
  

• Hand-held Rock Drills, Paving Breakers, Chisels & Moils:

  Hand-held Rock Drills and Paving Breakers, together with correctly matched Chisels and Moils, provide practical solutions for trenching, breaking, scaling, and selective demolition.

  
  

• Diamond Blades (115 mm–1200 mm):

  Harlen Supplies provides a full suite of diamond blades from 115 mm up to 1200 mm for concrete, masonry, and general-purpose cutting. The correct blade specification helps manage heat, cutting speed, and lifespan, supporting accurate cuts in structural work, slabs, roads, and blockwork.

  
  

  Construction Consumables: Keeping Sites Operational

  Unplanned stoppages often arise from missing basic consumables rather than major plant failure. Harlen Supplies offers essential construction consumables to keep sites running.

  
  

  • Site Consumables: Barrier nets, cones, tapes, flags, and road cones assist with traffic control, demarcation, and compliance with site safety requirements. These are critical in high-activity zones, blasting or breaking areas, and public interface points.

    
    

  • PPE and Safety Gear: Full-body harnesses, gloves, earplugs, and dust-masks support baseline protection for workers in drilling, cutting, working-at-height, and high-noise environments. Reliable PPE is a non-negotiable control in risk management on construction and demolition sites.

    
    

  • Mechanical & Fluid Handling Consumables: Hose-clamps, claw couplings, water hoses, s-slings, and specialised grease and lubricant products contribute directly to equipment uptime. Correctly specified hoses and fittings reduce leakage and failure, while appropriate lubrication extends component life on compressors, breakers, drills, and rotating machinery.

Why Harlen Supplies Fits Construction Requirements

Harlen Supplies is structured around the practical needs of contractors, demolition teams, civil works, and infrastructure projects:

• Rock-breaking and drilling focus: Core product lines are aligned with high-impact, high-wear applications where performance and integrity are critical.

  
  

• Alternative solutions with NexPand: Where conventional blasting is not feasible, NexPand and NexPand Large Hole provide a controlled, non-explosive option for sensitive or restricted environments.

  
  

• Integrated consumable range: Multiple operational needs, from rock-breaking tools to PPE and hoses, can be supplied through a single, technically aligned source.

  
  

• Local stockholding in South Africa: Regional availability reduces lead times and supports continuity on time-sensitive projects across Southern Africa.

  
  

Purpose-chosen Construction Products

For construction stakeholders working in residential foundations, industrial sites, civil infrastructure, or demolition and cutting operations, Harlen Supplies provides technically sound, purpose-chosen products that address real operational challenges, minimise downtime, and support safer, more controlled site environments.
