Saint-Gobain to Acquire D.S. Brown, American Specialist in Bridges and Airports
The group is expanding its North American construction chemistry platform to include bridge and airport equipment, a segment driven by the modernization of existing transport networks. The transaction remains subject to approval by U.S. competition authorities.
A Target Specialized in Joints and Waterproofing of Structures
Saint-Gobain signed a definitive agreement on October 15, 2026, to acquire D.S. Brown Company. This North American company designs, manufactures and supplies solutions intended for bridges, airports and other transport infrastructure. At this stage, the transaction has not been completed: the commitment has been made, but finalization still depends on several conditions precedent.
Based in North Baltimore, Ohio, D.S. Brown offers expansion joint and bearing systems for structures. Its catalog also covers pavement preservation and waterproofing. These are products that intervene on existing structures as well as on new construction sites, positioning the company in network maintenance as much as in its construction.
The company is expected to generate revenue of 90 million dollars in 2026. It employs 235 people and operates two production sites, one in Ohio and the other in Texas.
Saint-Gobain highlights the technical expertise of its future subsidiary and a business model based on prescription. Specifically, the company seeks to have its solutions retained from the definition of infrastructure projects, before the purchasing phase. According to the group, these two elements underpin D.S. Brown's leading position in North American transport infrastructure.
A Complement to the GCP, Fosroc, Chryso and Xypex Brands
Once the transaction is finalized, D.S. Brown will join the brands that Saint-Gobain already groups together in construction chemistry. The group cites GCP, with its Eliminator Bridge Deck Waterproofing and Safetrack Road Maintenance Solutions ranges, as well as Fosroc. It also mentions Chryso, present in concrete admixtures, and Xypex, specialized in waterproofing by crystallization.
This latest addition is recent: on October 2, 2026, Saint-Gobain finalized the acquisition of Canadian company Xypex, a transaction announced in July. The acquisition of D.S. Brown thus adds to an operation just completed on the same platform, this time with an anchor in transport structures in the United States.
According to the group, the combination should generate commercial and operational synergies, through cross-selling, prescription of high-value solutions and innovation. Saint-Gobain plans to leverage its own customer base to expand D.S. Brown's presence. The stated objective is to broaden the offering for the repair, protection and reinforcement of civil engineering structures.
The transaction is expected to be completed by the end of 2026. It remains subject to authorization from U.S. competition authorities as well as satisfaction of other customary conditions for this type of transaction.
A Transaction Aligned with the "Lead & Grow" Strategic Plan
The group links this acquisition to its "Lead & Grow" strategic plan, which aims to accelerate growth in high-value solutions in the infrastructure market. Construction chemistry occupies a central place in it.
Saint-Gobain generated revenue of 46.5 billion euros in 2025 and has 162,000 employees, present in 81 countries. Its headquarters are located in Courbevoie, in the Hauts-de-Seine.
The announcement comes as the stock had touched its lowest level in two years on October 6, 2026, before falling below the 66.12 € threshold on October 7. Two brokerages had then lowered their price targets on the stock.
