It is a fourth generation family company, founded in 1944, and one hundred percent national, the one that the president of AIP, José Eduardo Carvalho, directors António Poças and Domingos Chambel, directors and association technicians visited in Souto da Carpalhosa, Leiria. Pedro Faria, administrator of the Sival Group, and member of the AIP board, accompanied by CEO Inês Faria, recalled Joaquim Emídio Faria as one of the main pillars in the history of this innovative business, launched by engineers from the emblematic Fábrica de Cimentos da Maceira-Liz.

The entire manufacturing operation, including the research, development and product testing laboratory, of the representative Portuguese brand is carried out in the territory in which it is located, using three working shifts, advanced technology and a total of 140 workers.

The first, oldest company, is a recognized manufacturer of plasters and mortars for civil construction, which accounts for 90% of production, the ceramics industry (9.7%) and agriculture/soil correction (0.3%).

“We are the only producer of plasterboard in Portugal”, says Pedro Faria, highlighting the abundance of businesses in the past: “We were once 17 manufacturers, but over time they disappeared, precisely because they did not make the necessary investments to enter the markets, to be strong in relation to external competition”.

This year, Sival – Gessos Especiais expects to achieve a sales volume of around 15,100 million euros, a value achieved by transforming 5 thousand tons of gypsum per month into more than 100 products, a natural raw material imported from Morocco in the form of rock. Also called gypsum stone or calcium sulfate dihydrate, it is a calcium ore whose chemical composition corresponds to the formula (CaSO4.2H2O).

In the other manufacturing unit, also located in the same area, and under the command of Inês Faria, administrator in the fourth generation, tubes and profiles are produced through extrusion, plastics that supply civil construction (44.5%), capture of water (31.8%), infrastructure (15.7%), irrigation and agriculture (7.5%) and the recently added textile industry (0.5%). This year, it opened a new business area, in plastics, with the start of injection.

Located approximately 15 km from this city, in Várzeas, the two manufacturing units of the Faria family, Sival – Gessos Especiais, PME Líder for the 14th consecutive year, and Sival – Tubos e Perfis, PME Excelência and Líder in 2022, count years of dedication to the two sectors and markets they feed: Portugal, PALOP, Senegal, Europe and South America.

Sival – Sociedade Industrial da Várzea, Lda., founded in February 1944, was the birthplace of the business. It began its industrial activity with the manufacture of traditional plasters for the civil construction and ceramics industry. In 1946, Emídio Oliveira Faria, who would become the “alma mater” of the Sival group, joined the company and, in 1948, with the acquisition of the shares of the remaining partners, the company became the exclusive property of the Faria family.

In 1962, the plastics factory opened to produce tubes and accessories in (low-density polyethylene and PVC polyvinyl chloride sheet). During the 1960s, the evolution of the market allowed it to also begin manufacturing PVC blinds.

The constant concern in terms of technological evolution and diversification of industrial activity led the company to introduce, in the 1970s, the manufacture of the PVC profile known as wainscoting and, ten years later, the production of high-density polyethylene tubes; at the plaster factory, in turn, the production of pre-dosed plaster mixes began.

The nineties brought changes to both factories: in plastics, the production of unplasticized PVC tubes (PVC-U) and PVC frames and angles began; and, in plasters, it was the acquisition of new calcination furnaces and structures for the production and mixing of additive ceramic plasters. Initiatives that allowed Sival to achieve significant improvements in its production structure, due to the company's concerns about accessing increasingly demanding markets with greater added value.

The concern with the development of production capacity continues in this new century, through the focus on increasing the production of polyethylene and PVC pipes and corrugated PP (polypropylene) and PE (polyethylene) pipes, as well as through investment in new technologies in plaster factory.

The beginning of the 2000s was also marked by the certification of the brand's products, considering new market demands, customer needs in areas such as sustainability and efficiency, but also the unavoidable development and progress of the Sival Group.
