Water leaks in concrete bottom outlet valves chamber of a river dam.

Tens of thousands of sealed leaks - this is the experience we gained in variety of hydraulic structures, canals, tunnels and tanks in water menagement area, water supply systems and in industry.
We apply surface waterproofing and high pressure injection of epoxies, polyurethane resins and foams, hydrophilic acrylic gels and mineral grouts.
We contract and consult critical sealing projects e.g. in nuclear power engineering.
