Hydrophilic Polyurethane Chemical Grout
Hydrophilic is a nonflammable hydrophilic polyurethane resin designed to form a flexible gasket or plug joints and cracks in concrete from water infiltration. In its uncured form, Hydrophilic is a pale yellow liquid. When it comes in contact with water, the grout expands quickly and cures to a tough, flexible, adhesive, closed cell foam that is essentially unaffected by mildly corrosive environments.
Contains no volatile solvents.
High elongation creates tight seal in moving cracks.
Sealing leaks through concrete cracks and joints.
Saturating backer rod to seal joints by the gasket method.
