Sovereign Hydroseal
(New York, USA)


Uncontrolled water inflow and leak remediation into underground structures are some of the biggest challenges for engineers, owners of infrastructure, and operators of mines. Such inflow can lead to unsafe/hazardous conditions and endanger those who use and operate in them as well as impact performance of equipment and machinery.

Sovereign Hydroseal has developed and successfully implemented state-of-the-art solutions to stop water infiltration into underground structures. These efforts include the use of NOH2O®, a proprietary polymer-based emulsion grout, combined with engineered/professional installation techniques.
