Underwater Dam & Bridge Inspection Solutions

1. Underwater Dam Inspection

• Inspection of submerged dam surfaces and concrete structures
• Spillways, stilling basins and energy dissipation structures
• Intake structures, outlet works and submerged gates (where accessible)
• Visual assessment of concrete deterioration, cracks, spalling & exposed reinforcement
• Identification of visible seepage indications, erosion and sediment accumulation
• Underwater video recording, photographic documentation and inspection reporting

2. Underwater Bridge Inspection

• Submerged bridge piers, foundations and pile structures
• Visual assessment of scour around bridge foundations
• Underwater concrete surfaces — cracks, erosion, spalling and visible defects
• Submerged structural components and foundations (where accessible)
• Documentation of sediment accumulation and foundation exposure
• Video records, photo evidence and reports supporting maintenance planning

3. Technology & Methodology

• Remotely Operated Vehicles (ROVs) for underwater visual inspection
• Underwater cameras and lighting systems
• Video recording and photographic documentation
• Access to submerged and difficult-to-reach structural components
• Defect documentation and condition-assessment reporting
• Engineering review and recommendations based on scope and findings

🏞 Why it matters

Divers cost ₹2–5 lakh per inspection day and carry life risk. ROVs inspect the same surface for a fraction of the cost, in zero risk, with centimetre-positioned footage you can replay in review meetings years later. Ideal for dam safety reviews, post-flood assessments and bridge condition audits for irrigation departments, PWD and NHAI projects.
