CBGM®-70 is a ready-to-use, cementitious grout engineered for direct underwater application in offshore environments. Its unique formulation:
Instantly displaces water upon contact, ensuring full contact with substrates.
Maintains excellent flowability even in strong currents (tested at 3 m/s).
Develops high early strength (≥30MPa in 3 days) for rapid return to service.
Resists saltwater corrosion and chemical attack in tropical marine conditions.
Long-Term Durability: Achieves 79.3 MPa at 28 days for structural reliability.
Product Introduction
CBGM-70 is a high-strength shrinkage-compensating grout specifically engineered for demanding underwater and marine applications. Its rapid strength gain, reaching up to 23.9 MPa in just one day and 79.3 MPa at 28 days, ensures reliable and durable performance in critical infrastructure projects.
