UHPC Technology and the Ocean

 

In more than 25 years we have carried out a number of projects in the offshore industry and have developed special UHPC systems for many of our current customers.
The future for us started a few years ago in UHPC development, in terms of UHPC material development for floating offshore power generation, floating city constructions and coastal protection. The UHPC materials are ready for use today. These materials are far superior to all other materials.
