2. Non-Shrink Formulation: No settlement or cracking after curing.
3. Marine Environment Resistant: Resists sulfate, chloride, and sea spray.
4. Excellent Bonding: Strong adhesion to concrete and steel.
5. Fast Curing: Supports fast installation of turbines.
6. Stable in Harsh Conditions: Works from -10°C to 50°C.
1.Offshore wind turbine foundations (monopile, jacket, tripod)
2.Heavy equipment baseplates in marine environments
3.Pile cap and socket connections under dynamic load
4.Offshore booster station conduit frame foundation grouting.
Q: Is HGM-125 suitable for underwater pouring?
A: Yes, it can be used in submerged conditions with anti-washout properties.
Q: Can it resist marine corrosion and salt spray?
A: Absolutely. It’s specially formulated for marine durability.
Q: How fast can structures be loaded after grouting?
A: Light loads can be applied after 24 hours; full design load typically after 7 days.
