CBGM-5 is engineered as a low-density, buoyant grout for suction bucket foundations, ensuring stable installation in offshore wind farms.
Summary Benefits at a Glance:
Low Density – bulk density 680–750 kg/m³, reducing grout weight
High Buoyancy – improves suction efficiency and uplift stability
Long Flow Retention – initial fluidity ≥ 290 mm, ≥ 150 mm after 8 h, ensuring continuous placement
Volume Stability – 24 h free shrinkage = 0, reliable under marine and tidal conditions
Product Introduction
CBGM-5 is a non-shrink grouting material specially developed for offshore wind suction bucket foundations. Unlike conventional high-density grouts, CBGM-5 emphasizes low bulk density and buoyancy, making it particularly suitable for suction-assisted installation. It maintains excellent fluidity and flow retention for long-duration pours, even under tidal influence. The product delivers stable volume change, impermeability and resistance to marine conditions, ensuring safety and long service life of offshore wind foundations.

Product Usage
Suction Bucket Foundations – specialized grout for suction-assisted offshore wind turbine installation
Marine Engineering – grouting under tidal and underwater conditions requiring buoyancy and stability
Offshore Wind Foundations – anchoring systems needing low-density, non-shrink grout
Application Notes
Mix with clean water per recommended ratio; stir until uniform.
Place within 10 minutes after mixing; grout continuously from one side to avoid air entrapment.
Protect freshly placed grout; keep moist for at least 7 days.
Packaging: 25 kg moisture-proof bags.
.Shelf life: 6 months in dry, ventilated storage.
