The construction sector in Catalonia is dominated by established groups with broad service offerings. COMSA, for example, is a group operating in various sectors, providing solutions and services globally. SORIGUÉ has 70 years of experience in various sectors, focusing on innovation and sustainability. Molins specializes in manufacturing, marketing, and distributing cement products internationally, while COPISA CONSTRUCTORA focuses on infrastructure, industrial construction, and energy efficiency projects.
Many of these companies, like Molins (founded 1928), SORIGUÉ (1959), and COPISA CONSTRUCTORA (1959), were established in the mid-20th century, indicating a mature industry with deep roots. While Barcelona is a prominent headquarters city, several significant firms are based elsewhere, such as SORIGUÉ in Lleida and Molins in Sant Vicenç dels Horts.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
