Holistic Concrete Inspection
Holistic Concrete Chimney Stack Inspection
Scope: Holistic inspection of the entire chimney stack.
01 · Challenge
- Manual and localized void detection.
- Conventional NDT cannot effectively differentiate concrete layers and defects in concrete.
- Challenges in achieving consistent and accurate results due to irregularities, curvatures and surface roughness.
02 · Asset & access constraints
- Total scan area
- > 2,000 sqm
- Scan reference
- 1.5 m × 0.4 m in less than 2 minutes
- Project duration reference
- Approximately 1 month
- Inspection team
- 2 rope-access teams
03 · Inspection approach
The stack was divided into sections/grids, equipment was deployed across the inspection zones, and data was uploaded daily for analysis and interpretation before final reporting.
04 · Technology / deployment
- Microwave holographic imaging
- Rope-access deployment
- Grid-based data collection with daily data upload
05 · Findings & visual outputs
- Void detection with ground-truth reference
- Concrete damage / void volume (m³) visualization
- Corrosion / deformation around rebars (sqm)
- Heatmaps and 3D data overlays
06 · Customer benefit / decision supported
- Centimeter spatial resolution for fine defect detection
- Accurate inspection data supporting informed decision-making
- Rapid inspection supporting reduced downtime and time/cost efficiency
