High-grade material

High-grade material

The high-grade material, Duralen, is used in the production of the Carat tanks. This is an extremely stiff and impact-resistant material and is therefore ideally suited to the manufacture of underground tanks. The material does not tend to distort and is highly rigid, ensuring optimum stability of the underground tank and thereby guaranteeing a unique service life of several decades. What’s more, thanks to its chemical passivity and high resistance to environmental factors, Duralen is particularly suited to the underground storage of liquids, especially rainwater but also domestic waste water. And, the product is 100% recyclable.
