Gravity Foundation

Gravity Foundation

cte wind gravity foundation

The slab/gravity foundation for a steel or a concrete tower is the most common form of a foundation for wind turbines but yet remains a complex structure.

Note: a new, different and optimised type of gravity foundation has been developped by CTE Wind. Reach out to us directly if you require more informations.

Wind turbine generators (WTG) are becoming more and more powerful and the hub heights are increasing by the day. As a result, the concrete volume can reach more than 1000 cubic metres per foundation.

CTE Wind has optimized the bill of quantities (BOQ) massively over the last decades. We are continuing, by means of research, to work on effectful improvements in order to deliver resource-saving but reliable foundations.

Coöperatie Zuidenwind has poured the concrete for the foundation in Heibloem in the Netherlands and created the basis for the installation of their wind turbines. The foundation design and calculation for this project was done by CTE Wind Civil Engineering.
The expert in foundation design WTG suggested their Soft-Spot® instead of a typical pile foundation.

The significant advantages of CTE Wind’s gravity foundation:

  • Optimised and reliable
  • Easy readable drawings.
  • Easy transportable reinforcement bars.
  • Easy buildable reinforcement and shape for concrete pourring.

Continuous improvements

CTE Wind continuously improves this standard solution by taking into account the developments (size and performance) and also through close cooperation in research and development projects (tower manufacturer, universities, standardization bodies, etc.).

On the side, we would like to mention the possible life time extension by changing the assumptions of the fatigue loads.

CTE Wind adapts its gravity foundation to the existing soil conditions. Thus, several variants may be suggested. Furthermore, it can be combined with other CTE Wind design solutions, such as the SOFT-SPOT® or the high pedestal.

The customer will be supported and advised throughout the entire project by experienced geotech and civil engineers.
