The metro’s underground tunnels and stations are treated with Xypex Admix C‑1000 NF added during batching. By making this part of the structure itself, we avoided external membranes and ensured robust, water-resistant concrete in a high water‑table setting.

Product Used: Xypex Admix C-1000 NF

Scope: Tunnels, underground stations, and service shafts

Details: The product was added during batching to simplify construction sequencing and avoid reliance on membrane systems. It actively seals micro-cracks and prevents water ingress in high water table zones.

Outcome: Long-term waterproofing integrity for critical transit infrastructure.
