The foundation for safe, reliable immersed tunnels
Immersed tunnels play a vital role in modern transport networks, where long-term reliability has an impact on safety, connectivity, and economic resilience. Effective watertight sealing is critical to protect tunnel structures from water ingress, progressive deterioration, and unplanned disruption, all of which can compromise safety and significantly increase lifecycle costs. Through a lifecycle-focused approach, Trelleborg helps tunnel owners and contractors manage structural movement and extreme environmental conditions, enabling immersed tunnels to operate safely, reliably, and sustainably for generations.
