In practice, this means that geomembranes are used in many different projects in both geotechnical constructions and in connection with construction projects.

Mainly used in the following areas of use: Gas and water supply, agriculture, mining industry, chemical industry, semiconductor industry, pharmaceutical industry, civil engineering, building technology, compressed air supply, environmental protection, tunnel and dam construction. 

HDPE or EPDM is used for the most part, depending on the area of use.
