Rock Foundation – hard to beat CO2 emissions and costs

When solid bedrock is on the surface or at a maximum of two meters deep, Rock Foundation is an optimum choice. The loads are transferred from the tower to the ground through the Peikko adapter and 12 to 14 meters long FATBAR® Post-Tensioned Anchors. Each tower is supported with 40 to 60 FATBAR® anchors.

For example, a 5.5 MW turbine with a tower height of 120 meters uses:

  • 40 m3 of concrete (4 truckloads)
  • 5 t of steel and the Peikko adapter (1 truckload)
  • 48 pieces of FATBAR® 72 anchors (1 truckload)
