High strength grout with applied nanotechnology for grouting offshore wind turbine installations
SikaGrout®-9800 is a shrinkage compensated, cement based grout which when mixed with water, produces a homogeneous, flowable and easy pump able grout with exceptional mechanical and physical properties. Latest best binder packing models and applied cementitious nanotechnology produces a grout with superior technical performance and exceptional rheological properties.
-
C90/105 concrete strength class according EN206 and DIN1045
-
Can be installed with a continuous mixing and pumping process. Typical output rates of ≥ 20 m³/hour per mixing unit.
-
Quick return to service and removal of temporary supports due to high early strength build-up. ≥ 40 MPa @ 24hrs at 20°C.
-
Very good strength gain at low temperatures.
-
No segregation or bleeding to ensure consistent physical performance inside the grouted connection, and to prevent pump blockages.
-
Excellent fatigue resistance
-
No wash-out during below water grouting.
-
Pump able over long distances and large heights.
-
Specially graded sands and exceptional flow and low friction increases pump output, reduces installation times and costs as well as reducing pump pressures and wear.
-
Available as silo material.

Usage
SikaGrout®-9800 has been especially formulated for large scale, pump applications.
- Grouting of grouted connections in offshore installations, e.g. foundations of wind turbines or oil & gas installations.
- Typical applications are pile-sleeve and stab-in-pile grouted connections, clamp repair, leg filling etc…
- Grouting under very harsh conditions, e.g. offshore applications or below water grouting, at temperatures as low as 2°C or up to 42°C.
- All void filling from 30 mm to 600mm thickness where high strength is important.
