Dams & Levees

Indeed water flow control can significantly affect the economy of wide regions. Dams are usually built to generate electrical power, to feed canals and irrigation and water supply systems, to raise river water level to make them navigable or control the level during high water and low water periods, to create freshwater reservoirs and artificial lakes. Dams often have multiple functions; in developing countries, however, the capacity of building dams is an important step toward industrialization.

Dams being a barrier across a waterway to create artificial reservoirs, they can however differ in type and size. TREVI has been actively involved in the construction of new dams or in solving seepage problems to existing ones, thus tackling major engineering issues: geological and geotechnical issues require special attention, with respect to water-tightness of the dam body, walls and bottom; to this end, special technologies and systems have been designed, tested and used to set up “impermeable” screens, as well as soil treatment in order to dramatically reduce natural permeability.

Specialist Contractor for dams construction

The Trevi Group presence in the dam sector has a very long tradition, which dates back to more than half a century. Since 1953, year of the first intervention to the Pidima Buttress Dam in Greece, TREVI Group companies, worldwide leaders in dam construction and rehabilitation, have been committed to enhancing a crucial asset for mankind, that is water. 

The Trevi Group companies participated directly to more than 170 dam projects all over the world, covering all the underground specialized areas, from the initial phases of the preliminary investigations to the construction and the treatment of the foundations, until the remediation works in case of unsafe structures.
