Grouting for Wind Foundations

Wind turbine bases require grouts that can withstand dynamic loads and harsh environments without cracking. ZRETE’s cementitious grouting materials provide ultra-high compressive strength, shrinkage compensation, and excellent fatigue resistance to keep foundations secure both onshore and offshore. Formulated for easy pumping and long workability, these grouts ensure a solid connection between turbine tower and foundation, even in cold or marine conditions.

Product Matrix:

• CBGM-5 Wind Power Grout (Buoyancy Cylinder) – Lightweight, high-flow non-shrink grout for offshore turbine suction bucket foundations, ensuring full cavity fill and long-term stability.

• CBGM Antifreeze Grout (Low-Temperature) – Specialized grout that cures in sub-zero conditions, enabling winter installations by achieving high strength even in extreme cold.

• CBGM Onshore Wind Grout (High-Strength) – High-strength, non-shrink precision grout for onshore wind turbine pedestals and anchor bolt sleeves, providing robust anchorage and vibration resistance.

• CBGM-125 Ultra High-Strength Grout – 125 MPa grout with nano-fiber reinforcement for offshore wind turbine bases, combining ultra-high compressive strength with continual expansion to prevent shrinkage cracks.

• CBGM-70 Underwater Grout – Marine-grade anti-dispersion grout for offshore foundations, placed directly underwater with excellent bonding.

• Kuaizhuang Assembled Special Grouting Material – Fast-assembly grout designed for precast tower bases, enabling rapid installation with durable bonding.

Segmental Bonding Adhesives

Modern tall wind towers often use precast concrete segments that must act monolithically. ZRETE’s segment bonding adhesive is a two-component structural epoxy designed to firmly splice these segments together.

Product Matrix:

• Structural Epoxy Adhesive (Wind Tower Segments) – High-performance epoxy for precast wind tower joints, providing rigid, weather-resistant bonding.

Blade Maintenance & Anti-Icing Coatings

Wind turbine blades face relentless wear from weather and operation. ZRETE delivers solutions to preserve blade integrity and performance.

Product Matrix:

• JGN812 Wind Blade Repair Epoxy – Toughened epoxy resin system for blade repair, restoring structural integrity under cyclic fatigue.

• Ultra-Hydrophobic Anti-Icing Coating – Nano-engineered coating forming a water-repellent layer on blades, reducing ice adhesion and winter downtime.

Fiber Reinforcement for Foundation Concrete

As turbine sizes grow, foundation slabs and pedestals must control shrinkage and micro-cracking. ZRETE addresses this with PVA fiber reinforcement specifically tailored for wind farm concrete.

Product Matrix:

• Spiral PVA Fiber Reinforcement – High-modulus PVA fibers bridging microcracks, improving ductility and fatigue resistance of foundation concrete.
