What Carpi Tech does

Carpi Tech is a Swiss-headquartered specialty waterproofing contractor for hydraulic structures, founded in 1963 and operating through wholly-owned regional entities across Europe, the Americas, and Asia Pacific. The company designs, manufactures (via exclusive third-party producers), and installs proprietary polymeric geomembrane systems — SIBELON® and SIBELONMAT® — for dams, reservoirs, canals, hydraulic tunnels, shafts, pumped storage schemes, tailings dams, and traffic tunnels, with a documented service life exceeding 50 years for exposed installations and 100+ years for covered installations.

The core technical differentiation rests on the SIBELON® material family and the SIBELONMAT® underwater installation system, which allow waterproofing under extreme conditions including water heads up to 800 meters and underwater deployment without dewatering — a capability Carpi has commercialized through specialty diving partnerships. The company has completed more than 270 large projects across 40+ countries, including flagship references such as the Panama Canal Expansion's water saving basins (2016), the world's tallest Geomembrane Facing Rock Fill Dam at Las Bambas in Peru (235m, 2015), and the first zig-zag geomembrane core at Gibe III in Ethiopia (2009).

Commercially, Carpi operates a turnkey project delivery model providing single-source performance guarantees that combine engineering design, proprietary material supply, and installation services under fixed-price, quote-based contracts with enterprise and government clients. GTM is enterprise field sales — direct engagement with project owners, main designers, and as a specialist subcontractor — supported by eight regional offices that localize execution. The company holds ISO 9001:2015, ISO 14001:2015, and IQ NET certifications, and has historically reinvested in R&D around new installation typologies (GFRDs, zig-zag cores, underwater flowing-water systems) rather than pursuing geographic licensing models.
