Xypex Patch’n Plug was selected for its quick-setting capabilities, immediately addressing water ingress. Xypex Megamix II was used to patch extensive cavities,
offering a robust and durable solution. Over 2000 square meters of tunnel walls were coated with Xypex Concentrate and, enhanced with Xypex Xycrylic Admix, providing a superior waterproofing solution compared to traditional methods. This approach ensured permanent, effective waterproofing, of Xypex’s non-toxic Crystalline Technology’s global reputation for protecting structural integrity and resisting water leakage under extreme conditions.
