Tunnels
Xypex Meets the Challenge Deep Below the Surface
Whether transporting people through subways and tubes, moving vast amounts of stormwater or carrying electrical lines and switches, tunnels play a significant role in the modern world. Underground and often under bodies of water, tunnels can be seriously compromised by extreme hydrostatic pressure and water ingress.
There are all types of tunnels, and Xypex is universally recognized for waterproofing, protection and repair of these critical infrastructure components. For new construction or rehabilitation of existing tunnels, Xypex has a record of success based on thousands of applications in tunnels across the globe.

Raba Pedestrian Tunnel
The construction of the new Raba pedestrian tunnel was a vital infrastructure project designed to connect Ehitajate tee and Rääma streets in Estonia’s prominent spa town, Pärnu. The project faced significant hydrogeological challenges due to its immediate proximity to the Pärnu River, where the water table is consistently high.
Sumapaz Road Tunnel
The Sumapaz Tunnel, part of the busy Bogotá to Girardot route in Colombia, is a crucial transportation corridor that facilitates both tourism and cargo movement. However, the tunnel faced significant water ingress issues due to the surrounding topography, leading to serious structural concerns.
Cairo Metro Line 3 Phase 3 & 4
In the Cairo Metro Underground project, specifically for Line 3, Phase 4, Vinci served as both contractor and consultant, facing considerable challenges, particularly with the initial waterproofing material. To address these issues, the project team opted for Xypex Concentrate, a move that significantly improved the waterproofing of stations and water tanks within the project. A total of 12 tons of Xypex Concentrate was utilized, demonstrating its effectiveness in a demanding environment.
