Our Specialization
As a leading NDT lab, we specialize in a wide range of concrete testing methods to assess in-situ concrete properties, including:

Rebound Hammer Test
Used on RC members to determine the surface hardness and compressive strength of in-situ concrete.

Ultrasonic Pulse Velocity (UPV) Test
Helps to evaluate the quality and integrity of concrete and to measure the depth of cracks.

Profometer Test
Accurately detects reinforcement bars (rebar) and measures cover concrete thickness.

Half-Cell Potential Test
Determines the probability of corrosion of steel reinforcement within RC members.

Carbonation Test
Measures the depth of carbonation in concrete, a key indicator of durability.

Chemical Analysis
Laboratory-based testing to assess the presence of chlorides, sulphates, and pH value of concrete samples.
At GCT Lab Pvt LTD, all NDT methods are performed as per ASTM, IS, and international standards, ensuring accurate and reliable results.
