SikaGrout®-9650

Bulk supplied, high strength grout with applied nanotechnology for grouting offshore wind turbine installations

SikaGrout®-9650 is a shrinkage compensated grout which when mixed with water, produces a homogeneous, flowable and pumpable grout. Latest best binder packing models and applied cementitious nanotechnology produces a grout with superior technical performance, and exceptional rheological properties.

  • Compressive strength class C60/75, even at cold temperatures.
  • Available as silo material.
  • Can be applied in the shortest weather windows.
  • Excellent strength gain.
  • No segregation or bleeding to ensure consistent final physical performance.
  • For applications in a wide temperature range.
  • Excellent flow and pumping properties reduce installation times and costs.
  • Very fast grout installation: limited to no interference with the critical path of the installation vessel.
  • Pumpable through 2” grout lines.
  • Volume stable.

Usage

SikaGrout®-9650 has been especially formulated for large scale, pump applications.
  • For use as high strength grout in offshore foundations like monopiles using bolted connections
  • For rock socket structural grouting in offshore applications, or similar.
  • Grouting of structural and non-structural parts of offshore wind turbine installations, e.g as skirt backfill
  • Grouting under very harsh conditions, e.g. at temperatures as low as 0°C.

Application steps

NOTES ON INSTALLATION

  • Sands or other products that could affect the prod-ucts properties must not be added.

  • SikaGrout®-9650 which will be exposed to strong drying conditions, e.g. mortar which is directly exposed to heavy wind and/or direct sunlight, should be protected using appropriate curing agents.

  • As the powder may densify over time, especially when the goods are stored on the vessel in the offshore silos and exposed to many vibrations, the First-in / First-out principle is key to a successful grouting job.

EQUIPMENT
