At DJM Aerial Solutions, we deliver industry-leading internal stack inspection services across the UK using confined-space UAV systems. Designed for industrial clients in sectors such as petrochemicals, power generation, manufacturing, and waste processing, our drone-based inspections enable detailed, high-resolution assessments of internal stacks and vessels without the need for manned entry or costly downtime.
Why Choose Drone-Based Internal Stack Inspection?
Chimney, exhaust, and flue stacks are critical assets that require routine inspection to monitor structural integrity, corrosion, lining condition, and internal obstructions. Traditional inspection methods often involve scaffolding, rope access teams, confined space entry, and full rescue standby, which significantly increase safety risks, operational downtime, and costs.
At DJM Aerial Solutions, we provide a more advanced solution.
Our internal drone inspection service delivers:
- Zero Personnel Entry: Fully remote inspections eliminate the need for manned access into confined or hazardous vertical structures.
- Minimised Downtime: Inspections are completed rapidly, reducing the time your asset is offline and maximising plant availability.
- High-Definition Visual Data: Stabilised 4K video, stills, and live-feed capabilities provide detailed internal condition assessments.
- Early Fault Detection: Identify corrosion, refractory lining failure, cracking, scaling, blockages, and internal structural defects.
- Rapid Reporting: Fully annotated digital reports with actionable insights allow for fast, informed maintenance decisions

How Internal Stack Inspection Works
Using specialised UAV platforms engineered for GPS-denied and confined vertical environments, DJM Aerial Solutions conducts precise internal inspections of chimneys, flue stacks, waste gas stacks, and vertical process vessels with full control and stability.
Our advanced drone systems are equipped with:
- 360° Integrated LED Lighting: Full illumination of dark, restricted interiors to ensure maximum visual coverage.
- Stabilised 4K High-Resolution Cameras: Capture crystal-clear imagery and video for accurate defect detection.
- LiDAR Mapping (Optional): Generate high-density 3D point cloud models for structural deformation tracking, dimensional analysis, and detailed asset integrity assessment.
- Live Video Feed: Real-time data streaming allows engineers to monitor inspections as they happen, improving collaborative decision-making.
- Thermal Imaging (Optional): Identify heat anomalies, refractory breakdown, and thermal fatigue with precision.
We fly our drones inside the stack structure, vertical or tapered, to assess internal linings, wall condition, deposits, and signs of failure. This approach avoids physical entry and offers superior data acquisition in a fraction of the time.
Applications for Internal Stack Inspection
Our internal stack inspection services are ideally suited for a wide range of critical industrial assets, including:
- Chimney Stacks within power generation, energy-from-waste, and heavy industrial facilities
- Waste Gas Flues and Exhaust Ducts in incineration and emissions processing plants
- Boiler Stacks and Process Exhausts serving manufacturing, petrochemical, and refining operations
- Vertical Process Vessels, Kilns, and Towers used in cement, lime, metal processing, and materials manufacturing
- Gas, Chemical, and Combustion Stacks within chemical processing and storage facilities
Whether conducting scheduled integrity assessments, pre-maintenance inspections, or rapid-response surveys following system faults or alarms, DJM Aerial Solutions offers rapid mobilisation and delivers detailed, actionable data to support safe and efficient asset management.
