Structural Repair

Conducting structural problem analysis with modern diagnostic tools

Why Analyze Before Repairing?

Structural repair is not just about fixing what you can “see.” It is essential to identify the root cause—such as cracks, settlement, or deformation of beams, columns, and slabs—to prevent recurring damage. That’s why advanced structural diagnostic tools are indispensable.

Modern Structural Diagnostic Tools

1.1 Rebound Hammer Test

1.1 Rebound Hammer Test

Measures concrete compressive strength
Tests slab, column, and beam durability without drilling

1.2 Ultrasonic Pulse Velocity (UPV)

1.2 Ultrasonic Pulse Velocity (UPV)

Uses ultrasonic waves to check density and hidden cracks
Detects voids or concealed structural damage

1.3 Ground Penetrating Radar (GPR)

1.3 Ground Penetrating Radar (GPR)

Radar scanning for concrete structures
Detects rebar, pipes, and voids within structural elements

1.4 Core Sampling

1.4 Core Sampling

Extracts concrete samples for compressive strength testing
Validates non-destructive testing (NDT) results

1.5 Infrared Thermography

Identifies delamination, moisture, and leaks in walls or floors
Reveals hidden defects invisible to the naked eye

1.6 Crack Width Microscope & Monitoring System

1.6 Crack Width Microscope & Monitoring System

Monitors crack depth and expansion with precision sensors
Used to monitor whether cracks are deepening, widening, or remaining stable.

1.7 Load Test & Structural Health Monitoring (SHM)

1.7 Load Test & Structural Health Monitoring (SHM)

Simulates real load-bearing conditions
Uses strain gauges, pressure sensors, and displacement meters

Analysis & Reporting

Analysis & Reporting

Engineers evaluate structural damage.
Estimate remaining service life.
Recommend solutions such as steel reinforcement, CFRP strengthening, epoxy/cement injection, or foundation replacement.
