Loose stone foundation with igloo
To be realised on the ground floor to protect the dwelling from ground humidity.
An additional humidity barrier provided by the asphalt surface of a bituminous sheath returned on the perimeter walls up the height of the finished floor.
Covering of the installations
The installations are covered by the building firm before the plastering of the perimeter walls.
Dry sand in bags
The sand of varying granulometry is brought to the work site in bags, already dried to speed up the work phases.
Sand bag layer
Dry substructure in dried sand created in the floor above the technical installations.
Greaseproof paper or transpiring material is placed above the sand screed, to create a vapour barrier.
For ground floor dwellings it is advisable to create a layer of thermal insulation by laying a panel made of wood or cork fibre.
Hard wood-fibre underfloor (no glues)
Nailing of parquet
The solid tapped wood parquet is directly nailed to the hard wood-fibre underfloor.
Parquet laying finished
On completion of the work the surface of the parquet is perfectly calibrated (the innumerable gaps between one plank and the other are absent, unlike in the bonded version).
The parquet is covered with a sealant nylon layer to protect from atmospheric humidity and from subsequent works.
