- High early and final strength
- Flow retention for continuous placement
- Controlled expansion and volume stability
Wind energy / Foundation systems
Wind Turbine Foundation Grouting Solutions
High-strength, non-shrink cementitious grout systems for reliable load transfer in onshore and offshore foundations. Selection is based on connection geometry, flow retention, strength, exposure and installation method.
Application routes
One category, different foundation demands.
Use the application route to define the first product shortlist, then verify every value against the project specification.
Low-temperature wind grout
For projects requiring placement planning and strength development in colder site conditions.
- Temperature-specific method statement
- Verified mixing water and material temperature
- Protected curing and field quality control
Offshore foundation grout
For demanding marine installation routes and foundation interfaces.
- Long-distance mixing and pumping planning
- Marine durability review
- Project-specific flow and strength window
Recommended systems
Match the product to the grouted connection.
These are separate material routes for separate installation problems. Do not substitute a standard onshore grade for offshore, suction-bucket or direct-underwater placement without project verification.
Onshore wind turbine grout
CBGM Onshore Wind 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.
- Primary search intent
- wind turbine foundation grout
- Best fit
- Steel tower baseplate undergrouting
Offshore wind turbine grout
CBGM-125 Offshore Grout
An ultra-high-strength, high-modulus, shrinkage-compensated cementitious grout for offshore wind foundation connections, including jacket and monopile structures.
- Primary search intent
- offshore wind turbine grout
- Best fit
- Monopile and transition-piece grouted connections
Low-density offshore grout
CBGM-5 Suction Bucket Grout
A low-density, non-shrink grout developed for suction bucket and suction caisson foundation installation where buoyancy, long flow retention and stable volume are critical.
- Primary search intent
- suction bucket foundation grout
- Best fit
- Offshore wind suction bucket foundations
Specification logic
Performance is a system, not one strength number.
A successful wind turbine foundation grout must remain placeable through the planned installation, fill the geometry without voids, maintain volume stability and develop the specified mechanical performance under the stated test and curing conditions.
Flow & retentionMatch gap, hose length, batch cycle and pumping route.
Strength developmentConfirm early-age release and specified final-age class.
Volume stabilityControl shrinkage and maintain interface contact.
TemperatureSet material, water, substrate and curing limits.
Quality controlDefine field flow, specimen, frequency and acceptance criteria.
Installation framework
A six-point pre-pour check.
- 01Confirm gap & volume
Calculate net volume plus contingency and continuous-pour capacity.
- 02Verify temperature
Record material, water, substrate and ambient conditions.
- 03Prepare equipment
Match mixer, pump, hose diameter and standby capacity.
- 04Control mixing
Use the approved water ratio, sequence and mixing time.
- 05Place continuously
Maintain one-direction flow and avoid entrapped air or cold joints.
- 06Cure & document
Protect exposed grout and record field tests and specimens.
Technical FAQ
Questions engineers ask before product approval.
What grout is used under a wind turbine tower baseplate?
A high-strength, non-shrink cementitious grout is commonly specified to create continuous load transfer between the tower baseplate and concrete foundation. The final grade should be selected from the required strength, gap, flow, temperature, fatigue exposure and installation method.
Which strength class should a wind turbine foundation grout use?
There is no single universal class. Sino-sina project systems typically cover 80–130 MPa classes, but the approved value must follow the structural design, project specification, test method and curing condition.
Can the same grout be used for onshore and offshore foundations?
Not automatically. Offshore or marine exposure may require different flow retention, durability, installation planning and quality-control criteria. Select the system against the actual foundation type and exposure conditions.
What information is needed for product selection?
Provide foundation type, grout gap and volume, specified standards, compressive-strength ages, flow or spread requirement, ambient temperature, placement distance, mixing and pumping equipment, curing plan and project location.
