Rebar Cover Depth and Rebar Size Test.

Our Services

Ensuring Durability, Safety, and Compliance of Reinforced Concrete Structures

Rebar Cover Depth and Rebar Size Test is a critical non-destructive evaluation (NDT) used to determine the depth, spacing, and diameter of reinforcement bars (rebars) embedded within concrete. It plays a key role in verifying construction quality, assessing durability, and ensuring long-term protection of steel reinforcement against corrosion. At Global Lab, this test is performed using advanced rebar locators and concrete cover meters equipped with electromagnetic pulse induction sensors, enabling accurate mapping of reinforcement layout without damaging the structure.

Why Rebar cover DepthMatters.

Prevents Corrosion-Related Failures

By confirming sufficient concrete cover, the test helps safeguard embedded steel from corrosion due to environmental exposure.

Verifies Design Compliance

Ensures that rebar placement, spacing, and depth align with approved drawings and code-specified tolerances.

Non-Destructive and Rapid Assessment

Uses electromagnetic induction to locate reinforcement quickly and accurately without drilling or damaging concrete.

Aids in Structural Evaluation & Retrofitting

Essential for renovation, repair, or load enhancement projects, where accurate knowledge of existing reinforcement layout is critical before core cutting or anchoring work.
