Onshore wind turbine foundation grouting is not simply a filling operation. Under long-term dynamic loading, freeze-thaw cycles, installation tolerances and anchor-bolt stress concentration, the grout beneath the base plate must maintain full contact, transfer load efficiently and resist cracking over time. ZRETE’s onshore wind foundation grouting solution is designed for exactly these conditions.

Built around high-strength non-shrink cementitious grout, this solution can be adapted for standard onshore projects, cold-weather construction and higher-fatigue-duty foundations. It also supports combined use with steel fiber reinforcement and matching anchorage grouting materials when the project requires higher toughness or more demanding durability.

Why this solution

High early and long-term strength

The grout system is designed to deliver fast load transfer during installation while maintaining durable long-term structural performance.

Non-shrink stability

Micro-expansion and non-shrink behavior help maintain tight contact between grout, base plate and anchor system, reducing void risk and long-term loosening.

High flowability and pumpability

The material is formulated for practical field placement and efficient filling under base plates and around anchor bolts.

Better fatigue and crack resistance

For projects with higher cyclic loading or harsher service conditions, the solution can be paired with steel fiber reinforcement to improve toughness and crack resistance.

Cold-weather adaptability

For low-temperature jobs, a dedicated antifreeze wind power grout option can be selected to keep installation moving in severe winter conditions.

Typical application scenarios

• Onshore wind turbine base plate grouting

• Anchor bolt sleeve grouting

• Wind turbine foundation secondary grouting

• Cold-region wind farm installation

• Projects requiring higher fatigue resistance and long-term durability

• Foundations where full-contact bedding and non-shrink stability are critical

Recommended solution architecture

ZRETE recommends selecting the grouting package by project condition rather than using one generic product for every site.

For standard onshore wind foundation grouting, use a high-strength non-shrink grout specifically designed for base plates and anchor bolts.

For severe winter installation or regions where temperatures may fall below freezing, use the low-temperature antifreeze grout version.

For projects with higher cyclic loading, crack-control requirements or demanding durability targets, add copper-coated steel fiber as a reinforcement component.

For hybrid tower or post-tension anchorage systems, use the corresponding assembled special grouting material where the design requires it.

Recommended Product Matrix

Project proof

ZRETE’s wind materials are already used across multiple wind projects with different environmental demands.

In Harbin Binxian Phase II 150MW Wind Power Project, the antifreeze grout option was used for a region where winter temperatures can drop to -20°C or below, while the case highlights high early strength, non-shrink performance, pumpability and frost durability.

In Jingneng Bayannur 400MW Wind Power Project, CBGM onshore grout was combined with copper-coated steel fiber to improve crack resistance and fatigue durability under long-term cyclic loading.

For extreme-environment credibility, the Tibet Qiongjie high-altitude wind project demonstrates how Sino-Sina positions grout and matching materials for severe climate and installation conditions.

Strength Class Guide

Secondary module: anchorage duct grouting

For foundations or hybrid tower systems that use post-tensioned anchorage ducts, ZRETE also provides a matched duct grouting route. In these applications, the grout must maintain excellent pumpability, anti-bleeding stability and complete encapsulation of tendons or anchorage components.

If your project includes both base plate grouting and anchorage duct grouting, our team can recommend a combined material package.

Technical support and field guidance

ZRETE does not only supply grout. The company’s wind power solution system is built around product selection, field-condition matching and project support.

Recommended technical inputs before quotation:

• Project type

• Gap thickness

• Lowest construction temperature

• Required early compressive strength

• Need for steel fiber or cold-weather adaptation

• Foundation and anchor-bolt configuration

• Expected pumping / placement method

FAQ

What grout is recommended for onshore wind turbine foundations?

A high-strength, non-shrink cementitious grout designed for base plates and anchor bolts is the standard choice for onshore wind foundation grouting.

Do you offer a grout solution for cold-weather wind farm construction?

Yes. ZRETE provides a low-temperature antifreeze grout option for projects where winter installation and sub-zero performance are required.

Can the grout solution be reinforced for better fatigue resistance?

Yes. For projects with higher cyclic loading or crack-control requirements, the grout can be used together with copper-coated steel fiber.

Is this page suitable for offshore wind foundation grouting too?

No. Offshore wind foundations should remain on a separate landing page because the interface types, products and marine durability requirements are different.
