WELCOME TO SOVEREIGN HYDROSEAL

GROUTING EXPERTISE

Remediating uncontrolled water inflow into underground structures poses a significant challenge for engineers, civil/municipal infrastructure owners, and mine operators. Water intrusion can result in hazardous conditions, jeopardizing the safety of personnel within underground structures and also affecting the operational efficiency and life-span of equipment. Sovereign Hydroseal effectively addresses uncontrolled water intrusion by devising and implementing cutting-edge solutions to seal underground infrastructure. Sovereign’s state-of-the-art approach involves application of NOH2O®, a proprietary polymer-based emulsion (PBE) grout, using specially designed systems and techniques tailored to each situation.
