The certified divers of BEVALDIA (Manager of the branches PSOMAKARA & GAMSRO) cooperate efficiently and with high precision for underwater survey of underwater constructions (marine underwater inspection) and underwater survey of coastal structures. They have the experience and knowledge during the underwater survey to correctly identify information relevant to an underwater inspection and thus make recommendations for repairs and maintenance after the underwater inspection with detailed reports. The company is equipped to perform underwater survey of coastal structures and underwater survey of underwater constructions (bridges, dams, underwater tunnels, drilling rigs, floating docks, pipelines etc.) under adverse conditions, with poor visibility, high currents and great depths.
The detachment of the concrete coating has direct impact on the strength of the reinforced concrete. With the presence of cracks, seawater reaches easily the armament and eliminates the protective conditions created by the layer of oxides around the steel in the alkaline environment of concrete. In these conditions, corrosion of steel occurs and because of this considerable mechanical stresses are created which strain the concrete, which contribute to the further development of cracks, splitting the concrete cover and accelerate the corrosion process. Its necessary to periodically carry out underwater survey of coastal structures and underwater survey of underwater constructions, for predicting damage and maintenance.
The reinforced concrete structures exposed to the marine environment are often damaged, caused by corrosion of the steel. The seawater causes damage to concrete and corrodes, due to the presence of chlorides, sulphates, oxygen and other harmful elements.
BEVALDIA (Manager of the branches PSOMAKARA & GAMSRO) undertakes underwater survey of coastal structures and underwater survey for underwater constructions and their maintenance, such as:
- Underwater survey-Underwater maintenance pipelines.
- Underwater survey-Underwater maintenance floating docks.
- Underwater survey-Underwater maintenance of dams.
- Underwater survey-Underwater maintenance rigs.
- Underwater survey-Underwater maintenance bridges.
- Underwater survey – maintenance of submarine underwater tunnels.
