NDT Testing

NDT (Non-Destructive Testing)

Non-Destructive Testing (NDT) is a specialized technique used to assess the condition, strength, and durability of structural components without causing any damage. It helps identify hidden defects, deterioration, and safety risks in buildings, ensuring accurate decision-making for repairs and maintenance.

Why NDT Is Important

• Detects internal cracks, corrosion, and material weakness
  
  

• Helps in assessing structural stability and safety
  
  

• Provides reliable data for repair & rehabilitation planning
  
  

• Minimizes cost by avoiding unnecessary demolition
  
  

• Mandatory for many structural audits and redevelopment projects
  
  

Common NDT Methods We Perform

1. Rebound Hammer Test
Measures surface hardness of concrete to estimate compressive strength.

2. Ultrasonic Pulse Velocity (UPV) Test
Checks internal cracks, voids, and concrete quality using ultrasonic waves.

3. Core Cutting & Testing
Extracts a concrete sample for laboratory strength analysis.

4. Half-Cell Potential Test
Identifies corrosion activity in reinforcement bars.

5. Carbonation Test
Evaluates depth of carbonation to assess long-term durability.

6. Rebar Scanning (Cover Meter Test)
Locates reinforcement, spacing, and concrete cover thickness.

How NDT Helps Your Building

✔ Accurate diagnosis of structural health
✔ Prevents major structural failures
✔ Ensures compliance with building safety norms
✔ Essential for structural auditing, repairs, & redevelopment approvals
