In buildings without a basement, foundations and frost aprons can be dispensed with in order to create thermal bridge-free insulation. A lase-removing layer of foam glass gravel serves as pressure-resistant perimeter insulation. The foundation of the floor slab takes place on this gravel layer.
Alternative to conventional construction:
- Excavation of the excavation pit
- Excavation for and installation of the underground pipes
- Pressure test
- Creation of a level ground
- Installation of the foundation earthing (including connecting lug / professional connection to the reinforcement)
- Design of a geotextile on the entire surface (lateral protrusion: at least 1m)
- Insertion of the base course of foam glass gravel
- Leveling, slightly compacting
- Geotextile folded over at the top
- Lay out PE film to protect against penetrating concrete
- Set edge formwork Install
- reinforcement (plastic spacers so as not to damage the PE film)
- Concrete
the ballast base course must cantilever out from the side all around in order to make the floor slab frost-proof.
Foam glass gravel consists of approx. 98% recycled glass.
It is
- pressure-resistant
, - non-flammable,
- frost-resistant
, - impermeable to water,
it has a high seepage capacity and is about ten times lighter than gravel.
