Secil is one of the main cement producers in Portugal, founded in 1930. Although the central core of its activity is the production of cement, Secil is part of a group of about 40 companies that operate in complementary areas such as the production of concrete, hydraulic lime, mortars, coverings and also quarrying. Secil ensures its production for the Portuguese market through its Secil-Outão, Maceira-Liz and Cibra-Pataias plants. At the international level, Secil is present in Tunisia, where it has a cement plant, Société des Ciments de Gabès, which is mostly owned by it. It is also present in Angola, with a 51% stake in TecnoSecil, a company that operates the cement plant in Lobito, Angola. Secil also holds an important financial stake in the company Ciment de Sibline, s.a.l., located south of Beirut in Lebanon. Secil started its activity in Brazil in 2011, with the acquisition of a stake in Supremo Cimentos, a company founded in 2003, in Pomerode, Santa Catarina. In 2015, it took over the entire capital of Supremo Cimento and opened a new cement plant in Adrianópolis, Paraná, Brazil. Secil invested in a maritime terminal located in the Port of Terneuzen, in the south of the Netherlands, close to the Belgian border. In 2017, it acquired a set of assets from LafargeHolcim in Spain, which includes a cement terminal in Vigo, two quarries and thirteen ready-mixed plants in the Spanish regions of Asturias and Galicia. Semapa has held the entire share capital of Secil since May 2012. Semapa is a holding company listed on Euro Next Lisbon, with the Queiroz Pereira family as the majority shareholder, with strong traditions in Portuguese industrial and financial activities.
