Onshore wind turbine grout
CBGM Onshore Wind Turbine Foundation Grout
A high-flow, pumpable, non-shrink cementitious grout range for onshore wind turbine baseplates, anchor cages and anchor bolts. Strength grades are selected against the structural design and installation window.
Recommended uses
Where this material fits.
- Steel tower baseplate undergrouting
- Anchor cage and anchor bolt grouting
- Horizontal load-transfer joints
- Wind turbine pedestal and foundation interfaces
Performance benefits
What the system is designed to deliver.
- High early strength for construction sequencing
- Controlled expansion for void-free load transfer
- High flowability without mechanical vibration
- Grades for 80–130 MPa 28-day compressive strength
Technical data
Requirements and reported values, separated.
“Requirement” is the stated acceptance threshold or range. “Actual result”, “typical value” and “published value” are not guaranteed minima unless the requirement column says so. Final acceptance must follow the approved TDS, report, test method and project conditions.
