Company overview

Secil was founded in 1930 and is today one of Portugal’s leading cement producers. With an annual output of 4 million tons of cement, it meets more than 35% of the country’s demand for cement. Although cement production is its core business, Secil lies at the heart of a group of around 40 companies operating in complementary areas such as concrete, prefabricated concrete products, hydraulic lime, plasters, claddings, and others, as well as quarrying.

Internationally, Secil has a presence in Tunisia, where it is the majority shareholder in the cement company Société des Ciments de Gabès and Sudbéton (ready-mix concrete).The company is also present in Angola, with a 51% stake in Secil Lobito, which operates a cement plant in Lobito. Secil is also also the major shareholder in the Lebanese company, Ciment de Sibline, s.a.l., located south of Beirut (cement, ready-mix and precast units).

In 2015, Secil acquired the totality of Supremo Cimento, headquartered in Pomerode, Santa Catarina, Brazil. It finalized a new cement plant at Adrianápolis (Curitiba). In Portugal, the company developed an integrated structure for manufacturing and marketing cement, supported by a distribution network which allows it to supply its clients directly, or else through Sales Depots located throughout the country. Semapa holds the entire share capital of Secil since May 2012.
