Foundation grouting, sealing, testing and lifetime repair for the global wind industry – delivered by the crews the world's leading turbine manufacturers call first.
Four disciplines, one standard: flawless execution in any climate, from −40 °C in Finland to +40 °C in the Australian outback.
Ultra-high-strength foundation grouting, refined over 35 years and preferred by the world's leading turbine OEMs. Certified installers of market-leading materials.
Certified Triflex Towersafe partner. Waterproofing applied directly to foundations – even at −5 °C – cutting maintenance cost and extending turbine lifespan.
State-of-the-art facilities in Denmark simulating any climate on earth. Comprehensive testing of ultra-high-strength grouts for OEMs and their suppliers.
Inspection, crack mapping, injection works and life extension. We detect voids before they become failures – and keep turbines turning for decades.
We redefine how the energy sector approaches grouting. Specially designed mobile units deploy at speed, crews are trained beyond local compliance, and every pour is documented in a fully digital QA system.
Bases in the EU, US and Australia. Projects delivered on nearly every continent – desert heat, arctic cold, tropical humidity.
Purpose-built mobile grouting units minimize downtime and keep your installation schedule intact.
Complete documentation of every foundation, delivered within 72 hours. Transparency and compliance at every step.
People, environment and your green investment protected – safety is engineered into every procedure, not added afterwards.
A selection of recent sites. Every project delivered with full digital QA documentation.
Our Danish test facility simulates climatic conditions from arctic to tropical, studying how temperature and humidity affect ultra-high-strength grouting materials before they ever reach your site.
The world's leading turbine manufacturers and their suppliers rely on our testing for onshore and offshore mockups alike.
Wherever your project is located, an Østermark crew is closer than you think.
Safety is paramount. We protect our people, the environment – and your green investment.
