Stable wave power constructions with MagnaDense

Wave and tidal technology are used to capture energy by ocean surface waves. The wave power machinery can be kept in place by an anchor, foundation or counterweight made with high density concrete or filled with a heavy loose aggregate such as MagnaDense.

The high density of MagnaDense will ensure that:

  • the wave power generator maintains the placed position.
  • the ballast has a long lifetime due to abrasion resistance in addition to the aggregates non-reactivity with seawater.
  • you can be flexible with your design.

Take a look at below video to see how MagnaDense provides extra weight and requires less volume under water.
