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 Arrabida 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.

Beyond the inevitable technological changes and a growing environmental awareness, the highlight has been Semapa’s purchase of 51% of Secil’s capital and 100% of CMP – Cimentos Maceira e Pataias, in 1994. CMP originated in the Maceira-Liz plant, inaugurated in 1923, and the Cibra-Pataias plant, founded in 1950. Since 2011 Semapa holds the entire share capital of Secil.

Many milestones have been passed throughout its history. The following are among the key events:
