These pre-formed ponds are not only made of weather resistant, frost-proof, root-resistant and environmentally neutral LLD-PE plastic, but the decorative surface is based on natural stone. This granular surface offers ideal conditions for the settlement of pond biology and not only blends in particularly well with a natural environment, but is also sustainable: The material is 100% recyclable. The different shapes are based on some of the most beautiful lakes in the world. Five planting and depth zones offer diverse design possibilities.
