RPM International to Acquire Italian Waterproofing Maker Volteco

Acquisition strengthens RPM's portfolio of waterproofing solutions.

 RPM announced that a definitive agreement has been signed for the acquisition of Volteco S.p.A., an Italy-based leading supplier of below-grade waterproofing solutions, for its Tremco Construction Products Group (Tremco CPG). This strategic acquisition brings a unique and differentiated technology platform to Tremco CPG. 

Headquartered in Ponzano Veneto, Italy, Volteco specializes in advanced waterproofing technology with calendar year 2025 sales of €28 million. The company is recognized for its AmphibiaTMwaterproofing sheet membrane. Volteco also produces a line of bagged powder goods for patch and repair applications, alongside flexible liquids, mortars, resins and damp-proofing materials.

“Volteco is an excellent complement to the product lines of our Tremco Construction Products Group. This acquisition provides Tremco CPG with new technologies that can be leveraged through its global sales force to drive growth and enhance its ‘Power of One’ value proposition for customers.”

Frank Sullivan, RPM chairman and CEO.

Volteco’s cutting-edge waterproofing solutions have been pivotal in numerous high-profile projects, including the protection of historical landmarks in Venice and the construction of modern facilities like the Santa Giulia Ice Hockey Arena in Milan, a key facility for the Milan Cortina 2026 Winter Olympic Games.

Other notable applications include waterproofing for the strategic public work of an underground tunnel connecting the Abruzzo Regional Citadel to the L’Aquila bus terminal, a hub for intercity connections to over 22 cities in Italy, including Naples and Rome, and ensuring the structural integrity of Y-40, the world’s deepest thermal pool.

The transaction is expected to close in the second quarter of fiscal 2027, subject to customary closing conditions.

“Volteco is an excellent complement to the product lines of our Tremco Construction Products Group,” stated Frank Sullivan, RPM chairman and CEO. “This acquisition provides Tremco CPG with new technologies that can be leveraged through its global sales force to drive growth and enhance its ‘Power of One’ value proposition for customers.”
