Compelling. MATERIAL & PRODUCT PROPERTIES

Choosing vitrified clay pipe systems for open trench or underground installation of sewers is a decision for the future: in terms of cost efficiency, environmental friendliness and social responsibility. Virtrified clay pipe systems easily meet the stringent requirements for a safe, reliable and long-lasting service lifetime, which not solely is a merit of the outstanding properties of the material but also of its sustainability.

Cost efficiency, Eco-friendliness, Intergenerational equity
