Saint-Gobain strengthens its presence
in construction chemicals in Indonesia

On December 30, 2025 Saint-Gobain formed a JV with a subsidiary of Indocement Tunggal Prakarsa (a publicly traded Indonesian cement company 53% owned by Heidelberg Materials) to acquire Indocement's mortars business in Indonesia. The JV will be 60% held by Saint-Gobain with the remaining 40% held by Indocement Tunggall Prakarsa.

Indocement's mortars business is well-established in Indonesia with three production lines under the Tiga Roda brand and estimated sales of close to €20 million in 2025. Tiga Roda is a leading brand in white skim coat for finishing and is very complementary to Saint-Gobain's existing mortars business, Cipta Mortar Utama (CMU), both in product categories and geographic reach, strengthening customer intimacy across Indonesia.

Saint-Gobain has been present in Indonesia since 1995 and currently operates 14 production lines and employs around 1,300 people in the country. CMU is the leading player on the Indonesian market, thanks to 8 mortars production lines across the country, a comprehensive product portfolio and a network of close to 30,000 points of sale. CMU also benefits from Saint-Gobain's large presence across construction chemicals in Indonesia, thanks to its GCP (concrete admixtures and cement additives) and FOSROC (cement additives, resin flooring and technical mortars) brands.

The newly formed JV will leverage the strengths of Saint-Gobain's CMU, as well as those of Indocement, a leading cement manufacturer in Indonesia, to accelerate growth on the promising mortars market.

This acquisition is part of Saint-Gobain's strategy to further strengthen its business profile, in line with its "Lead & Grow" plan. It enhances Saint-Gobain's presence in the high-growth Indonesian market and is fully aligned with the Group's strategy to strengthen its worldwide presence in construction chemicals.
