What are pressure-waterproof tunnel sealing systems with integrated injection systems (DWA-I)?

Pressure-waterproof sealing systems with integrated injection systems (DWA-I) are specially designed systems used to seal tunnels against pressing water with hydrostatic pressure exceeding 10 meters of water column (1 bar). These systems have the same basic structure as the DWA system but are enhanced with integrated injection devices. These injection systems allow sealing material to be injected later if necessary, to repair leaks and ensure the watertightness of the tunnel.

Why is sealing crucial?

Sealing tunnels is essential to ensure the long-term stability and safety of the structures. Particularly for tunnels exposed to high water pressure, a pressure-waterproof sealing system is vital to prevent water ingress and avoid damage to the tunnel structure. An integrated injection system allows for quick and effective repair of potential leaks or concrete faults, increasing the lifespan and reliability of the tunnel.
