SikaGrout®-9600

Bulk supplied, offshore grout with applied nanotechnology for grouting foundations of wind turbine foundations

SikaGrout®-9600 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.

  • Excellent strength development 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: no interference with the critical path of the installation vessel. Grout installed while bolts of the foundation are initially tensioned.
  • Pumpable through 2” grout lines.
  • Volume stable.
  • Installation with continuous and closed grouting process. No batching of individual mixes.

Usage

SikaGrout®-9600 has been especially formulated for large scale, pump applications.
  • For use as high strength grout in offshore foundations such as monopiles using bolted connections
  • For skirt backfilling in offshore applications
  • Grouting under very harsh conditions, e.g. at temperatures as low as 0°C.
