RepoStruct 40
High-Performance, Polymer-Modified, Fibre-Reinforced Repair Mortar
hahne RepoStruct 40 is a one-component, pre-batched, polymer modified, shrinkage-compensated, fibre-reinforced repair mortar. Designed for both pourable and spray applications, it offers superior mechanical strength, low permeability, and excellent bond with old concrete. It is ideal for structural and large-volume repairs requiring thicknesses of 10 mm to 50 mm in vertical or overhead sections.
- 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
- 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
