VAwS (Ordinance on Installations for Handling Water-Polluting
Substances) – Specialist Company BQS 8.1, SKZ/TÜV-LGA
Quality guidelines for pipes, shafts and components in landfills


In the plastics technologies pipe construction, sewer construction and ventilation, we lay plastic pipe systems as full wall pipes, wound pipes, large pipes, multiple pipes, air ducts, and we produce specific complementary special shafts. We also fit ventilation for our customers. The configuring and laying of plastic pipes using the more cost-effective, trenchless laying methods, such as the HDD method, burst lining or long pipe lining are also lines of our business in rehabilitation cases.
