What is a insulating suspended ground floor?
It is the structural and horizontal element that separates a building from the ground.
In other words, it is a floor that separates the building from the land.

What is it for?
To avoid pathologies, humidity and radon gas entry into the building.

Is it mandatory?
Since December 2019 it is mandatory for new buildings that are on the list of municipalities affected by radon gas zone II of the Technical Code.
( I am leaving you a link below to find out)

What types are there?
Here my list of suspended ground flooring systems ordered from bio-efficiency priorities:
– half-timbered sanitary floor
– ytong sanitary floor (most common in Spain, also with higher insulation values)
– metallic framework sanitary floor
– sanitary floor of unidirectional beams and ceramic or concrete caissons
– bidirectional sanitary slab of plastic cassettes

My professional recommendation:
Add to the design whenever possible a sanitary floor to avoid pathologies and radon gas entry.
