Sealing of high water ingress

When constructing a building pit, or during the excavation of a tunnel, there is most likely a chance that water is gushing out. Or there is a very big flow of water that needs to be stopped before any further works can be continued. For the challenging job to block the water the one component, water reactive, polyurethane resin PC Leakinject Uni 6816 E can be used for a first blockage. Another option is the ultra-fast, two component, polyurethane injection resin PC Tunnelinject range.
