An 8.16 km underground metro tunnel in Agra, engineered against water ingress and joint leakage under high groundwater conditions.
About Project
8160-meter-long underground tunnel.
Challenges
Critical challenges of water ingress, joint leakage, and potential structural weakening due to high groundwater levels. Maintaining long-term tunnel integrity while ensuring uninterrupted metro operations required an effective, adaptable solution for sealing construction and expansion joints under variable hydrostatic pressure.Our Solutions
Swell Bars combined with Reinjectable Hoses provided a reliable, self-expanding sealing system that blocked water ingress and maintained leak-proof joints throughout the tunnel. The reinjectable hoses allowed for future maintenance and enhanced durability under high-pressure conditions. Download the Swell Bar BrochureDownload the Re-injectable Grouting Tube Brochure
