The technical installations are laid on the concrete slab or wood planking foundation.
A layer in sand and cement/cellular cement/cement and polystyrene is built over the technical installations. The ecoconstruction layer consists of Roman lime and cork/lime and crushed pottery/lime and granulate.
On top of the layer built to cover the installations, an extruded polystyrene panel is laid with crosslinked polyethylene heating pipes.
In ecoconstruction the extruded polystyrene insulating panel is replaced with a wood or cork fibre panel. The crosslinked polyethylene heating pipes may be replaced with copper pipes.
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.
Dry substructure in dried sand created in the floor above the underfloor heating installation.
Above the block in sand and placed on oiled paper or transpiring fabric to create a vapour barrier.
Gypsum fibre panel
Underfloor created with hard gypsum fibre panels.
Nailing of parquet
The solid tapped wood parquet is directly nailed to the hard gypsum-fibre underfloor.
Parquet laying complete
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.
