  1. Homogeneity Assessment: We evaluate the uniformity of the concrete, ensuring consistent quality throughout the structure.
  2. Detection of Imperfections: The test helps identify cracks, voids, and other imperfections in the concrete, ensuring structural integrity.
  3. Monitoring Structural Changes: We detect any changes in the concrete structure that may occur over time, allowing for timely maintenance or repair interventions.
  4. Quality Assessment: The test assesses the quality of the concrete in relation to industry standards, ensuring compliance with requirements.
  5. Comparative Analysis: We compare the quality of different concrete elements, ensuring consistency and compatibility between components.
NDT Testing

Half Cell Potential Test: Assessing Corrosion Activity in Reinforced Concrete

At Global Lab, we offer precise, accurate, and reliable testing of the electrical half-cell potential of uncoated reinforcing steel. Our services are accredited by NABL and comply with the requirements of ASTM C 876:91 (Reapproved 1999).


The half-cell potential test estimates the corrosion activity of reinforcing steel in concrete. It helps assess the severity of corrosion, guide rehabilitation efforts, and predict remaining service life.

  1. Rapid and Cost-effective: Non-destructive survey method for quick corrosion evaluation.
  2. Rehabilitation Guidance: Determines the extent of corrosion, aiding in effective repairs.
  3. Quality Assurance: Ensures the durability of repaired concrete structures.
  4. Service Life Prediction: Estimates the remaining service life, assisting in maintenance planning.

Carbonation Test

At Global Lab, we offer precise, accurate, and reliable carbonation testing services. Our tests are accredited by NABL and comply with the requirements of EN 14630:2006.


  1. Objective: The carbonation test measures the depth of the carbonated layer near the surface of hardened concrete, providing insights into the carbonation process. It can be conducted on-site or in the lab using test specimens or concrete cores.
  2. Understanding Carbonation: Carbonation is a natural process where carbon dioxide from the air reacts with the calcium-bearing phases in concrete, converting them into calcium carbonate. Cement paste, with calcium hydroxide (Ca(OH)2), has a high pH of at least 12.5.
  3. Choose Global Lab for accurate carbonation testing. Our expertise ensures reliable results and valuable information about the carbonation depth in your concrete structures.

Rebar Mapping & Cover depth of concrete

At Global Lab, we offer precise, accurate, and reliable testing for concrete cover depth and bar diameter. Our tests are accredited by NABL, following the requirements of BS 1881:204

Purpose of the Test:

  1. This test is used to estimate the position, depth, and size of reinforcement within concrete. It provides valuable information on their usage, applications, expected accuracy, and factors that may affect the results. Concrete cover refers to the minimum distance between the surface of embedded reinforcement and the outer surface of the concrete (ACI 130). The depth of concrete cover can be measured using a cover meter.
  2. Rely on Global Lab for comprehensive testing of concrete cover depth and bar diameter. Our expertise ensures accurate results, enabling you to maintain the integrity and quality of your reinforced concrete structures.

Crack Depth and Crack Bar Monitoring: Ensuring Concrete Integrity
