Sandwich tanks

Outstanding innovation

With the sandwich construction method we have conceived a double-shell wall construction with intermediary heat insulation. The single components from outside to inside are: 

  • the outer skin of reinforced concrete 
  • the inner insulation 
  • the load-bearing element

Sandwich construction at the construction site means that we complete not only the prestressed concrete tank but also the heat insulation and covering during the short erection period. 

The facing formwork of reinforced concrete is extremely robust and long-lasting – particular designs like wood or clinker structure are possible if desired.
