Basic idea of Lewis technology is to create as thin and, respectively, as light structure as possible, which would be applicable to wooden beam ceilings, while retaining load carrying capacity, stability and longevity properties of mass concrete. Lewis dovetail-shaped profile initially performs function of permanent formwork, and after consolidation of concrete – provides armature functions.

  • Complete reconstruction projects, such as apartments, offices, hotels, attic reconstruction, warehouses, and libraries.








  • Premises of apartments and private houses, where there is increased humidity, such as bathrooms, kitchens, balconies, outdoor terraces.












  • Newly erected buildings, where constructive solutions are necessary without unnecessary load on bearing structures.









Lewis structure provides for load carrying capacity, insulation and fire resistance properties, which correspond to modern requirements and valid norms.
