High-Performance, Polymer-Modified, Fibre-Reinforced Repair Mortar
A polymer-modified fibre-reinforced repair mortar designed for structural repair of damaged concrete. It offers excellent adhesion, improved tensile strength and crack resistance, making it suitable for patch repairs, surface restoration and structural rehabilitation.
Features and Benefits
- High compressive strength with early strength gain
- Low rebound and excellent pumpability
- Shrinkage controlled for crack-free repairs
- Excellent bond to concrete and reinforcement
- Chloride-free and non-corrosive
- Compatible with HAHNE protective coatings and waterproofing systems
Area of Applications
- Restoration of damaged or spalled structural concrete
- Jacketing and rebuilding of columns, beams, and walls
- Repair of fire-damaged and chloride-affected concrete
- Large-area reinstatement of industrial and marine structures
- Micro-concrete infill behind shuttering where vibration is difficult
