SF400 Series is a very rigorously tested breakwater. It is used today in all the world’s oceans. SF400 Series has been under continual development for the past 30 years and has survived all of the recent storms and hurricanes that it has been exposed to. This is due to our very unique system which has been designed to absorb and distribute stress when the loads are increasing tremendously during severe storms. SF400 Series, like all of our breakwaters, is doubly reinforced with the market’s thickest concrete surfacing layer, which guarantees a strong pontoon with a very long lifetime. The amount of reinforced concrete in a breakwater is easy to compare with others, by simply checking the weight.
