Floor / double membrane storage
Contemporary alternative
Our double membrane gas storage tanks offer a modern alternative without conventional slurry storage tanks as a foundation. Flexible in installation, we adapt to your system - whether floor slab, ring foundation or concrete ceiling. They are mounted in a stainless steel flat profile as standard, other options are possible.
Round, square, oval - shape and volume can be customised. Rely on flexible, modern and future-oriented gas storage with our innovative double membrane gas storage tank.

A double membrane gas storage tank is a flexible gas storage system with two independent membranes. The inner membrane stores the gas, while the outer membrane is stabilised by the supporting air pressure and provides weather protection.
The air-filled space in between provides the necessary stability, enabling safe and adaptable gas storage.
You can rely on us for everything from advice, sales, planning and customisation of the membrane to installation ready for acceptance.
Advantages
- Gas storage membranes for biowaste and food waste: Resistant to oils, long-chain hydrocarbons, high emission and odour density, without H2S limit value.
- Pre-assembled floor membrane with integration of condensate drain and gas extraction lines during installation, laid on a floor fleece to protect the floor membrane
- Metal components made of stainless steel
