Saint-Gobain demonstrates innovation and performance for underground infrastructure at World Tunnel Congress 2026

Saint‑Gobain will participate in the World Tunnel Congress (WTC) 2026 in Montreal, where it will showcase its comprehensive, high‑performance construction chemicals offering for underground construction. Bringing together the expertise of Chryso, GCP, Fosroc, and Weber, Saint‑Gobain will present an integrated portfolio designed to address the most demanding challenges of modern tunnelling and underground infrastructure.

As urbanisation accelerates worldwide and surface space becomes increasingly constrained, underground construction is playing a critical role in delivering mobility, resilient infrastructure, and sustainable development. These projects are often executed in highly technical, complex and challenging conditions, requiring reliable solutions that ensure performance, durability, and long service life.

At WTC 2026, Saint‑Gobain’s booth will showcase a comprehensive portfolio of solutions designed to address the demands and challenges of today’s underground projects.

Comprehensive solutions for underground applications

Saint‑Gobain’s underground construction offering covers a wide range of applications and methodologies, including SEM/NATM, TBM, cut and cover, immersed tube tunnels, shafts and metro stations, tunnel entrances, precast and ready‑mix plants.

Key solutions include:

• TBM solutions, including a large portfolio of precast segment solutions, backfill grout admixtures, tail seal greases, soil conditioning polymers, and water control injection systems
• SEM/NATM solutions, with a wide range of shotcrete solutions such as concrete admixtures, synthetic fibres, accelerators, completed by complete waterproofing and water control products
• Cut & Cover integrated solutions, designed to secure durability, watertightness, and performance with specialty waterproofing membranes, grouts and high-performance admixtures
• Waterproofing systems, comprising pre‑applied and liquid spray‑applied membranes designed to provide fully bonded, long‑lasting protection against water ingress and environmental contaminants
• Concrete admixtures and fibres for lining concrete, diaphragm walls, segmental construction, and immersed tunnel applications, optimising workability, durability,  circularity and sustainability
• Repair, protection, and finishing solutions for underground structures and stations, extending service life and ensuring long‑term performance

Combining innovation, proven technologies, and expert technical support, Saint‑Gobain delivers high‑performance solutions for underground construction worldwide. Meet our experts at Booth B1907 during WTC 2026 to discuss underground construction challenges and discover how our construction chemicals solutions can support successful project delivery.
