Ground / double membrane storage
Modern alternative
Our double membrane gas storage tanks are a modern alternative without conventional slurry storage tanks as a foundation. Flexible with regard to assembly, we can easily adapt to your system - whether floor slab, ring foundation or concrete ceiling. As standard version, they are mounted in a stainless steel flat profile, however, other options are also possible.
Round, square, oval - shape and volume are individually selected. Rely on flexible, modern and future-oriented gas storage with our innovative double membrane gas storage tank.

A doubleOur 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 between the membranes provides the necessary stability so that safe and adaptable gas storage is granted.
Rely on us for everything you need: from preliminary advise, sales, planning and customisation of the membrane up to the final 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 ground membrane with integration of condensate drain and gas extraction lines during installation, laid on a ground fleece in order to protect the groundmembrane
- Metal components are made of stainless steel
