The use of KAPPAX prevents the build-up of Radon gas: a natural but harmful radioactive gas, and a known carcinogenic.

Kappax is a new system for creating ventilation spaces as an alternative to gravel and brickwork, a more viable option from a technical and economical point of view for civil, industrial, public buildings and sports centres.
Furthermore, the system is ideal for the distribution of technological systems and plants under tile.
The use of the Kappax system in infrastructures lets you cast monolithic foundations in one go, to create a solid structure with notable savings in terms of concrete. Monolithic ventilated foundations are very stable and lightweight, reducing the weight bearing on the ground and the mass on which a seismic event will act.

Ventilation spaces created with Kappax formworks are particularly effective to:

• prevent the build-up of rising damp, thanks to the ventilation spaces, with the air ducted outside the building.
• prevent the build-up of Radon gas in places with scarce ventilation in contact with the ground; Radon is harmful and known to be the second cause of lung cancer.
• favour natural thermo-regulation thanks to the air space which, in contact with the ground, has a higher temperature than the surrounding atmosphere in winter and a lower temperature than the same in summer.

Terminology and links

Radon
Radon is an extremely volatile odour-less and colour-less natural radioactive gas.
It is formed as a result of the radioactive decay of natural uranium, and contaminates the ground (in particular lava, tuff, pozzolana), rock and water to some extent, in which it can be dissolved.
It generally enters buildings through cracks and small holes in cellars and other underground areas.
