When it comes to underground construction, mining, or infrastructure repair, shotcrete has proven to be one of the most versatile and efficient methods of applying concrete. But while the benefits are widely known—strength, speed, and adaptability—questions often arise around choosing the right shotcrete contractors and understanding the shotcrete price per m².

If you’re planning a project and want to get clarity on shotcrete application, budgeting, and contractor selection, this in-depth guide is for you. We’ll explore everything from what shotcrete is and why it’s used, to real-world pricing insights and how to find a qualified shotcrete partner like Altecrete, a leader in innovative sprayed concrete systems.

What is Shotcrete and Why It Matters

Shotcrete, also known as sprayed concrete, is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This method offers immediate bonding and structural support without requiring conventional formwork.

Applications Include:

• Tunnel linings
  
  

• Mining and underground reinforcement
  
  

• Slope stabilization
  
  

• Swimming pools
  
  

• Infrastructure repairs (e.g., bridges, retaining walls)
  
  

There are two main types:

• Dry-Mix Shotcrete (Gunite) – Water is added at the nozzle
  
  

• Wet-Mix Shotcrete – All ingredients are mixed before entering the hose
  
  

Both types are used by shotcrete contractors depending on project scope, material requirements, and site conditions.

Why Hiring Professional Shotcrete Contractors Matters

The quality of shotcrete application is only as good as the contractor behind it. Proper mixing, spraying technique, nozzle control, and curing are critical for long-term performance. Poorly applied shotcrete can lead to delamination, cracking, or even structural failure.

1. Experience in Similar Projects
   Choose a contractor like Altecrete, which has extensive experience in mining and infrastructure projects across South Africa.
   
   

2. Access to High-Quality Mixes
   Specialized formulations like Minecrete offer superior durability and adhesion, tailored to underground conditions.
   
   

3. Use of Modern Equipment
   Reliable contractors invest in up-to-date shotcrete equipment that ensures consistency and reduces rebound waste.
   
   

4. Trained Personnel
   Certified nozzlemen and experienced teams ensure each application meets safety and performance standards.
   
   

5. Post-Application Support
   Leading providers offer follow-up services, mix adjustments, and structural testing.
   
   

Understanding Shotcrete Price per m²

A common question is: How much does shotcrete cost per square meter? While costs vary depending on project size, type, and environmental factors, having a baseline understanding is essential for accurate budgeting.

Key Factors That Influence Price:

General Price Range

Based on Altecrete’s internal references and market trends, typical shotcrete price per m² can range from:

• R600 to R1200 per m² (±) for standard applications
  
  

• Higher for custom thickness, waterproofing additives, or underground mining conditions
