GALAXIE PU SF is a single-component, hydrophilic polyurethane injection grout designed for sealing active and intermittent water leaks in concrete and masonry structures. The resin reacts only when it comes into contact with water, forming a super-flexible polyurethane seal capable of accommodating movement while resisting high hydrostatic pressure.
Once cured, GALAXIE PU SF remains highly flexible with a controlled expansion profile, making it suitable for leaking cracks, joints, and water-bearing substrates. The solvent-free formulation reacts with fresh, saline, and mineral water and can be installed using a single-component high-pressure injection pump, making it well suited to remedial waterproofing and tunnel sealing applications.
