French building-materials major Saint-Gobain is strengthening its Latin American footprint through a completed acquisition in Peru and a new plasterboard production line in Brazil.
Saint-Gobain has completed the acquisition of QSI Productos para la Construcción, a construction-products company in Peru, while announcing plans to build a fourth plasterboard production line at its facility in Bahia, Brazil. The two moves expand the group’s presence in construction chemicals and light construction across the region.
Expanding Construction Chemicals in Peru
The acquisition of QSI Productos para la Construcción strengthens Saint-Gobain’s construction chemicals platform in Peru. The company already has an established presence in the country through brands including Weber and Z Aditivos, while its regional platform was further expanded through the acquisition of Soquimic in 2025.
Saint-Gobain said the QSI acquisition strengthens its position in key Peruvian end markets, including infrastructure and mining. Financial details of the acquisition were not disclosed.
The transaction builds on Saint-Gobain’s strategy of expanding its construction-solutions portfolio through targeted acquisitions while strengthening its local operating platforms.
Fourth Plasterboard Line Planned in Brazil
Alongside the Peru acquisition, Saint-Gobain has announced the construction of a fourth plasterboard production line at its site in Bahia, Brazil.
The company inaugurated its third line at the site in 2024, and the latest expansion will further increase its plasterboard manufacturing capacity in the Brazilian market. Once the new expansion is completed, the Bahia site is expected to host South America’s largest plasterboard production line, according to reporting on the company’s announcement.
The investment is aimed at supporting the group’s light-construction business and meeting demand for plasterboard and related construction solutions in Brazil.
Strengthening a Regional Platform
The two initiatives highlight Saint-Gobain’s continued expansion across Latin America through a combination of acquisitions and manufacturing capacity additions.
In Peru, the QSI acquisition adds to the group’s construction-chemicals platform. In Brazil, the new production line expands industrial capacity in a market where Saint-Gobain already operates an established plasterboard manufacturing base.
Together, the moves strengthen Saint-Gobain’s position across two complementary segments of the construction-materials market: construction chemicals and light construction.
Focus on Sustainable Construction
Saint-Gobain has positioned the Latin American expansion within its broader “Lead & Grow” strategy, with a focus on supporting growth in sustainable construction solutions.
The group’s approach combines local manufacturing, established brands and selective acquisitions to expand its presence across construction value chains.
For the region, the investments also reflect the continuing importance of construction chemicals and lightweight building systems as markets develop around infrastructure, housing and industrial activity.
Saint-Gobain’s latest moves demonstrate a clear two-track approach to growth in Latin America: acquiring complementary businesses while simultaneously adding local manufacturing capacity.
The Peru acquisition strengthens the group’s construction-chemicals platform, while the Brazil expansion adds further capacity in plasterboard and light construction.
As construction markets across Latin America evolve, Saint-Gobain’s strategy of combining local production, technology, established brands and targeted acquisitions positions the group to deepen its regional presence.
