- Primostar Group AS is an international construction materials and structural engineering technology company that specializes in membrane-free waterproofing and durability solutions for underground reinforced concrete structures. The company develops, manufactures, and distributes integrated white tank waterproofing systems designed to replace conventional external membranes, enhancing structural longevity and reducing environmental impact. Its core offerings comprise the proprietary WPM (Waterproofing Material) system, which includes WPM crack-inducing waterstop profiles for controlled shrinkage cracking; metal sheet waterstops with specialized coatings for sealing construction and movement joints against pressurized groundwater; crystalline waterproofing chemical admixtures that penetrate concrete matrices to provide self-healing properties for micro-cracks; injection hose systems and accessories for post-construction joint sealing; and specialized swelling waterstop tapes and sealants. In addition to material manufacturing and distribution, the company provides technical consulting, waterproofing design engineering, structural crack control planning, site inspection, and warranty-backed supervision services for commercial real estate developers, civil engineering contractors, and infrastructure builders. Primostar Group AS serves clients across Northern, Eastern, and Southern Europe, with active operations and distribution networks in Estonia, Latvia, Lithuania, Sweden, Finland, Ukraine, and Turkey, while expanding into North America. Founded through its core predecessor operating company Primostar OÜ in 2000 and restructured under the holding company Primostar Group AS in 2024, the enterprise is headquartered in Tallinn, Estonia. The group operates through several subsidiaries, including Primostar OÜ, manufacturing entity Primostar Tootmine OÜ, Primostar SIA in Latvia, Primostar UAB in Lithuania, Primostar Group AB in Sweden, Primostar LLC in the United States, and Primostar Group Inc. in Canada. In recent developments, Primostar Group AS completed its initial public offering on the Nasdaq First North Baltic market, commencing public trading under the ticker symbol PRIMO in June 2025. To drive international growth beyond Europe, the company executed a strategic North American expansion in early 2026 through the incorporation of wholly owned operating subsidiaries in the United States and Canada. Supporting its market entry and technical validation in the United States, the company entered into strategic research and market-analysis partnerships, including a collaboration agreement with Columbia University under the ClimateTech Expertise Network in late 2025 and a memorandum of understanding with the University of Miami in 2026. Furthermore, Primostar Group AS expanded the geographic reach of its intellectual property by securing patent protection for its proprietary Crack Control System technology in Ukraine in 2026, while continuing to advance the international commercial adoption of its low-carbon, membrane-free waterproofing technologies.
