High hydrostatic pressure from surrounding water features result in frequent water seepage onto road pavements, especially into the tunnel structure, reducing the bonding strength of the premix material, leading to the formation of potholes and road stains on the road/tunnel pavements. Solution sought to address public concerns and safety hazard due to the defects. Marina Coastal Expressway tunnel to be used as pilot site for the developed solution, with an expected outcome of at least 80% detection rate. The solution requirements are: - To detect water seepage movement and divert/direct them away into the tunnel’s drainage system to reduce the formation of potholes and road stains; - No restriction on the inspection/detection of seepage into any specific method; - To generate report for seepage movement within 1 week after inspection; - To withstand traffic loading without displacement in a road tunnel environment and should not result in further road defects;
