Rebar Mapping Test.

Our Services

Non-Destructive Mapping of Reinforcement Layout and Steel Congestion Zones

The 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 that generate high-resolution rebar maps. These maps enable engineers to visualize the reinforcement network in slabs, beams, columns, and foundations accurately.

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.
