Waterproofing for Major Projects

Volteco’s systems have been used to protect historic landmarks in Venice and in the construction of the Santa Giulia Ice Hockey Arena in Milan, a venue for the Milan Cortina 2026 Winter Olympic Games.

Other applications include the underground tunnel connecting the Abruzzo Regional Citadel with the L’Aquila bus terminal and Y-40, a thermal diving pool in Italy. The projects demonstrate the range of structural and below-grade applications served by Volteco’s waterproofing portfolio. 

Expanded Building-Envelope Portfolio

Tremco CPG brings together building-envelope manufacturers and brands including Tremco, Nudura, Dryvit, Willseal, Flowcrete, Nullifire and Vandex. Its businesses operate across North America, Europe, Asia-Pacific, India and Latin America.

The group combines regional distribution with technical support, training and testing for commercial, industrial and residential construction. RPM’s stated rationale for the acquisition is to introduce Volteco’s technologies through that broader international organization. Pasted markdown(10)

The closing adds below-grade waterproofing membranes, liquids and resin-based materials to a major supplier of special purpose coatings, expanding its ability to supply integrated building-envelope systems.
