Saint-Gobain acquires waterproofing specialist Xypex Chemical

| By Mary Bailey

Saint-Gobain S.A. (Courbevoie, France) has entered into a definitive agreement to acquire Xypex Chemical Corp. (Richmond, B.C., Canada), a global leader in crystalline waterproofing admixtures and coatings. Xypex provides its differentiated solutions in more than 100 countries and employs approximately 170 people, with sales of C$110 million expected in 2026. The company has established itself as the reference brand in crystalline waterproofing — with a strong position in infrastructure and specification-driven construction markets — in North America, as well as in Asia-Pacific and Europe.

The acquisition will strengthen Saint-Gobain’s construction chemicals platform and enhance cross-selling and upselling, by adding a highly differentiated and complementary technology to its existing waterproofing solutions portfolio, which includes membranes (GCP Preprufe, FOSROC Proofex), liquid-applied systems (Stirling Lloyd Eliminator, GCP Silcor), and injections and repair technologies. Xypex solutions have been specified in hundreds of demanding projects around the world, positioning Xypex as a leading brand for engineers and specifiers in the waterproofing space.

Crystalline waterproofing enhances the durability and service life of concrete structures, helping extend asset life and reduce maintenance requirements. It can be used either as a standalone solution or in combination with membrane systems in situations requiring the highest level of waterproofing performance.

Leveraging Xypex’s leading crystalline waterproofing technology — featured in flagship products such as the Admix C-Series, Concentrate, and the new Bio-San technology — Saint-Gobain will further strengthen its presence in the attractive non-residential and infrastructure markets, including transportation, water, and underground construction applications. The transaction will also create significant commercial and operational synergies through the combination of Xypex’s specification-driven model with Saint-Gobain’s global footprint, distribution network and construction chemicals platform.

The transaction is subject to customary conditions and regulatory approvals and is expected to close in the fourth quarter of 2026. This acquisition is fully aligned with Saint-Gobain’s “Lead & Grow” strategic plan, aimed at strengthening the Group’s leadership in construction chemicals, as well as accelerating its growth in the non-residential and infrastructure markets.
