An almost 100 years old History

An exceptional location, offering the possibility of expeditions by land and sea, close to Setúbal on the River Sado and blessed with a rich seam of limestone and marl – these were ample reasons for a cement factory to open in the Arrábida mountain range, where materials had been mined since the 18th century.

As the result of the merger of two companies operating in the region, in 1930 Secil – Companhia Geral de Cal e Cimento – was established. Since those far off days in the first half of the 20th century, there have been many changes.

1994 and 2011 were milestones in the history of Secil. In 1994, Semapa acquired 51 % of the capital of Secil and 100 % of the capital of CMP. CMP – that stands for Cimentos Maceira e Pataias –  owns the cement plants in Maceira-Liz and Cibra-Pataias. In 2011, Semapa acquired all remaining shares of Secil.
