Sika SikaFix HH Hydrophilic – Expanding Polyurethane Chemical Grout
SikaFix HH Hydrophilic is a low-viscosity, expanding polyurethane grout designed for sealing leaks in concrete cracks and joints. When it comes into contact with water, it rapidly expands and cures into a flexible, high-strength, adhesive closed-cell foam that effectively stops water infiltration. The product forms a tight, durable seal that remains unaffected by mildly corrosive environments. It is nonflammable, solvent-free, and ideal for applications requiring flexible waterproofing in dynamic concrete structures.
Key Features:
- Expanding hydrophilic polyurethane resin for superior water sealing
- Forms a flexible, high-strength seal for moving cracks
- Expands up to six times its original liquid volume
- Nonflammable and free from volatile solvents
- Maintains performance in mildly corrosive environments
- Effective for sealing cracks, joints, and backer rod applications
