Concrete breakwater as a coastal defense

In recent weeks, I have met people from the Coast Guard in
some European countries. I wanted to learn more about the
current protection of coastal areas, because I think we can
work together with our experience in the application of
UHPC® (Ultra High Performance Concrete) in the offshore
industry to develop some new solutions to make our shores
safer against soil erosion, beach erosion, eroding cliffs and
shoreline erosion.
 
Hard costal protection structures are
  • Sea dykes
  • Sea walls
  • Revetments
  • Groynes
  • Offshore breakwater
For all these structures, UHPC® can be used, directly casted or sprayed, as precast concrete elements or as a combination with asphalt as UHPC®Phalt.
Many of these solutions come from the experience and applications
of our mining, road construction and offshore operations.

We use UHPC® in port areas, jetty constructions, underwater 
foundations for wind turbines, tide power plants, canal locks,
sheet piling and hydroelectric power plants.
    UHPC® is beneficial for these applications because
    UHPC® is absolutely seawater resistant, lifetimes of 100
       years are quite possible
    UHPC® is already watertight compared to standard concrete
       in low layer thicknesses
    UHPC® achieves extreme strength
    UHPC® is extremely corrosion resistant
    UHPC® is extrem wear resistant
    UHPC® can be shaped in any geometry and any natural
       stone surface can be replicated
    UHPC® does not require a repair service
    UHPC® including reinforcement can withstand enormous
       loads.
      What I particularly noticed here are these particularly
      ugly breakwaters, that make the whole coastal area safe
      but also make the nature of the coast less attractive.
      Some of these constructions give me the impression
      that coast is protected for the next war.

      Dear architects and designers, it must be possible to
      develop according to the nature of the coast correspond
      to breakwaters and tsunami fuses.
      Already for years we supply UHPC® material for
      artificial rock landscapes. They are so integrated in
      nature that they can hardly be distinguished from the
      real rocks.

        Your criticism is justified in some cases. These things look really ugly. To protect industrial port areas make these designs quite useful but in all other areas you could give yourself a little more trouble.
        With UHPC we have styled some rock gardens including waterfalls and pools. In most cases, sprayable UHPC has been used. If we wanted to have special surfaces, the rocks were cast. I could even imagine making the rock structures directly on the water, it is possible with UHPC and it saves a lot of transport, which in turn reduces costs.

        Once reports on these garden designs, to give readers an idea of how well it works with UHPC.

          Hi Franchis, thank you for your commentary and references to garden architecture with UHPC. Bernd will write an article in this blog in the next few days.

        I have read various reports about the problems of the island inhabitants on the South Seas islands. They are increasingly struggling with the ever-accelerating climate changes, such as rising sea levels, enormous rainfall and flooding, and extreme storms. In addition to coastal protection, should not it also be possible to develop storm and rainproof accommodation with UHPC that does not lead to cost extortion?

        Basically there are certain possibilities of using the properties of UHPC to make the local structures and constructions much safer and more resistant to extreme climatic influences. But for that we need a lot of information about the local constructions and construction methods. We can not copy solutions, each country has its own specific possibilities. We are happy to help.
