Shells

North Sea shells are (crops) used for all kinds of different applications, because they have some very useful and unique properties. Firstly, shells have a low specific weight. In addition, they have good water permeability. They also have a thermal insulating effect and they contain a lot of calcite. For these reasons, washed North Sea shells are often used as a lightweight foundation or as insulation in crawl spaces and other areas with moisture and mold problems. But they are also used to make shell paths in parks and forests.
