Single-walled and double-walled underground tanks
Depending on the general conditions and legal regulations at your site, you can store your media safely in our underground containers made of PE-HD and PP.
Drainless double-walled collection pit for water-polluting media
The monitored underground tank is an important step towards underground storage of media. Underground tanks must be constructed in accordance with water and building regulations. A gap built into the tank wall is constantly checked for leaks. A leak detector immediately sounds the alarm if the tank is damaged. Our tank can be used in water protection areas without any problems.

Which fabrics can be filled?
All media can be stored in our PE100 containers in accordance with the DIBt media list 40-1.1.
Containers may also be used for the storage of other liquids if it is proven by an expert opinion to be determined by the DIBt that storage is possible.
What is the advantage of underground tanks?
Double-walled tanks with a vacuum safety contour do not require a separate drip tray.
Furthermore, VSK tanks are approved by the DIBt for installation in areas at risk from earthquakes.


PE-HD as a base for underground tanks with vacuum safety control (VSK)
This system represents a new development with decisive advantages in the field of coiled pipes made of PE-HD:
- High chemical resistance
- Absolute safety against biogenic corrosion
- Absolute tightness in the system
- Long service life
- Self-cleaning properties due to low wall roughness
- Easy connection to PE-HD sewer pipes and manholes
- Low weight, therefore easy to install
- Special solutions can be easily realised

- High safety and decisive advantages thanks to PE-HD technology
- Problem-free storage of, for example, 98% sulphuric acid (H2SO4), nitric acid (HNO3), sodium hypochlorite (NaOCl), acetic acid (CH3COOH), hydrochloric acid (HCl) or other aggressive acids
- Problem-free storage of caustic soda, potassium hydroxide solution or other alkaline solutions
