Rebar Mapping Test.

Our Services

Non-Destructive Mapping of Reinforcement Layout and Steel Congestion Zones

Rebar Mapping Test is an advanced non-destructive testing (NDT) method used to determine the location, spacing, orientation, and distribution of steel reinforcement embedded within concrete. It provides a complete visual layout of reinforcement placement — crucial for retrofit design, condition assessment, and structural evaluation without damaging the surface. At Global Lab, we employ state-of-the-art rebar scanners and electromagnetic cover meters.

Why Rebar mappingMatters.

Ensures Structural Safety and Integrity

Provides an accurate understanding of internal reinforcement layout — critical before drilling, coring, or retrofitting to avoid damaging embedded steel.

Verifies Construction Quality

Confirms that reinforcement placement matches design drawings, ensuring compliance with code-specified spacing and alignment tolerances.

Aids in Rehabilitation and Load Enhancement

Essential for engineers planning structural strengthening, anchorage installation, or post-tensioning — by revealing existing rebar positions.

Detects Reinforcement Congestion and Deficiencies

Highlights irregularities like excessive spacing, overlaps, or void zones that can affect concrete compaction and durability.
