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.
