The Irra Tunnel, a centerpiece of the Pacífico III highway, is one of the most important infrastructure projects in western Colombia. As with any underground construction, ensuring watertight integrity is crucial. The solution: PVC geomembranes that act as a robust barrier to prevent groundwater from entering the tunnel. This barrier protects the concrete lining, avoids corrosion of metal elements, and ensures long-term structural safety.
Leister Technology in Action
To achieve consistent and high-quality seams under the demanding conditions of underground work, Geosoluciones used Leister’s TWINNY T5 automatic welding machine. Known for its digital control system, precise temperature management, and user-friendly operation, the TWINNY T5 enabled clean, uniform, and reliable welds across the entire tunnel surface. Its robust performance and ease of handling not only helped to ensure defect-free joints but also reduced installation time — a crucial advantage in large-scale infrastructure projects.
146 Kilometers of Progress
With a total length of 146 kilometers, the Pacífico III highway project significantly enhances connectivity in western Colombia. The Irra Tunnel forms a critical segment of this corridor. Geosoluciones' work, supported by Swiss welding technology, ensures that this key section remains protected against water ingress for decades to come.
