  • the invention makes it possible for the first time to produce an artificial, defined subsoil, referred to in this context as a foundation cushion, in the system of a foundation solution which also comprehensively fulfills the building physics requirements and, moreover, has soil or subsoil-improving properties.
  • This foundation cushion is to be used primarily for frost-resistant flat foundations that achieve optimum thermal design from the point of view of energy-efficient construction using sustainable building materials.
  • the core component of this system solution is glass foam granules. Glass foam granules are an ecologically harmless material that is biocompatible and does not result in any destruction of nature.
  • the glass foam granulate creates a cost-effective, optimally external, perfectly thermal bridge-free and highly load-bearing thermal insulation under the cover layer. Due to the high reliability of glass foam granules, it is possible to deliberately dispense with a conventional floor panel with the classic, internal structure.
  • the glass foam granule layer replaces the capillary-breaking layer because it itself has capillary-breaking properties, the cleanliness layer and also the usual external insulation. It's not just a cost Saved but also the comfort significantly increased. In particular, this could also reduce the depth of excavation.

  • the first intermediate layer which represents an intelligent separating layer between the soil and the glass foam granules, avoids the mixing of soil and glass foam granules. Such a mixture often leads to a reduction of the heat-insulating properties and the capillary breaking effect of the glass foam granules.

Due to the regionally, different compression of the glass foam granules can be entered into the tasks or the requirements of the foundation cushion defined.
