Østermark Grouting

At Østermark Grouting, we deliver high-precision grouting and sealing for wind turbine foundations, both onshore and offshore. With over two decades of experience and more than 1,000 projects completed annually, we partner with developers, OEMs, and asset owners across Europe, North America, and Australia.

Our work goes beyond new installations. As foundations begin to show signs of wear, our Aftermarket services help preserve and restore structural integrity, supporting continued safe and efficient turbine operation.

Our Aftermarket services include:

• Visual inspection – identifying cracks, degradation, and early signs of foundation damage
• Tower movement measurement – tracking movement or instability to assess structural condition
• Repair – targeted interventions to restore foundation strength and performance
• Lifetime extension – tailored strategies to prolong the safe use of existing foundations
• Repowering support – modifying or reinforcing foundations to accommodate new turbine models

We bring hands-on experience and dependable execution to every project — whether it’s a new installation or the maintenance and recovery of aging onshore assets.
