Dolphin is a construction company specializing in the containment and lining of reservoirs and the sealing of underground structures .

Dolphin has executed many major projects in Egypt where lining was required, including lining of open- earth reservoirs for water storage and wastewater treatment. Dolphin has also carried out several projects for the lining of major tunnels (underpasses) and was entrusted with the structural sealing and lining of basements and foundations for key major buildings in Egypt. When area sealing was required for the protection of roofs of major national buildings, such as the Cairo International Exhibition Halls, Dolphin was immediately called upon.
