The foundations for wind turbines are a critical element of the complete structure. Each turbine manufacturer has their own specific type of foundation but there are a few key elements that are common to all foundations:
• Mass concrete (from 120-500m3)
• Reinforcement (from 10-50 tonnes)
• Basket or “can” (weighing from 2 to 15 tonnes) cast into the foundation to connect to the tower
" have experience building a variety of foundation for the different turbine manufacturers. We have built turbine for Enercon, Gamesa, GE and Vestas.
When constructing the foundations it is critical to ensure quality control is of high importance. During the construction the reinforcement is meticulously checked against the plans to ensure that all the bars are tied correctly as laid out in the plans. At all times the levels of the basket or can (whichever is specified) are checked to ensure that they comply with the minute tolerances set out in the specification. Finally, when it comes to pouring the concrete "Wind Farm
" ensure that the concrete is placed and compacted correctly. We also ensure that the mass pour is managed properly to ensure that there are no gaps in concrete supply and everything runs smoothly on the day of the pour. After each pour the foundations is protected against the elements to ensure that the concrete cures properly, i.e. to prevent surface and thermal cracking.
