Offshore Foundations

A Crucial Structural Component

Complete Grouting Service

Since the start of erecting wind farms offshore, Ducorit® UHPC has been a crucial structural component of foundations for offshore wind turbines (Monopile, Tripile, Tripod, Jacket), substations and met masts.

With the use of our UHPC comes a complete grouting service which includes consultancy, design, planning, and supply of grouting material, installation, test sampling and documentation for any offshore structure design and installation scheme.


  • Project Management - Grouting projects are always handled by a project manager and a leading supervisor who ensure that the projects are carried out safely, according to QHSE standards and on time.  The grouting installation/application is verified by Det Norske Veritas (DNV) and Germanische Lloyd (GL).
  • Skilled and Experienced Supervisors - The supervisors working offshore are skilled, experienced, and dedicated to providing the best possible service to our customers.  Throughout a grouting installation/operation, our supervisors take samples according to a strict quality plan for testing and documentation.
  • ​Optimized Offshore Equipment - Over the years, we have developed specialized equipment for grouting offshore to ensure our customers an efficient and cost-effective installation.  The grouting equipment fulfills the requirements for quick mobilization and the design takes the limited space at the installation vessels into consideration.


Ducorit® is a pumpable, Ultra-High Performance Concrete (UHPC) material especially developed for grouted structural connections. The core of the Ducorit® products is the unique Densit® Binder. The different properties of our many products are obtained by adding aggregates such as quartz sand or bauxite.

Ducorit® products are characterized by:

  • Extremely high strength and outstanding fatigue properties
  • Minimal shrinkage
  • Ultra high bond between Ducorit and steel
  • High early-age strength
  • High inner cohesion i.e. no mixing with seawater
  • Low hydration heat


Ducorit® is mixed with water and pumped through flexible hoses into the annuli to be grouted. Grouting with Ducorit® can be carried out above and below sea level using our purpose built processing equipment.

Ducorit® products are manufactured under strict supervision and quality inspected in accordance with ISO 9001:2000 standards and certified by Lloyd’s Register Quality Assurance
