UNDERWATER INSPECTION

Inspection of underwater concrete structures is required for maintenance and repair works. Methods, types and objectives of underwater concrete structure inspection is discussed. The service life of any underwater concrete structure for example bridges and wharves and other marine structures are based on maintaining physical condition of both superstructure and substructure.

Visual Inspection

This inspection is not required to clean the structure in this method while this level of inspection is carried out and this makes this level of inspection the most rapid method among all other inspection levels. The main purpose of the inspection is to determine the condition of the structure below the sea level

NDT Test Underwater

This test is to examination an object or material with technology that does not affect its future usefulness. NDT be used to determine the actual conditions based on data obtained, estimation of thickness values, estimation of pile height and conditions based on NDT testing features, NDT provides an excellent balance of quality control and cost-effectiveness.
