CHAPTER 2 - The problems of acceptable foundation

Also today the direct contact with the soil exposes people to the discomfort caused by rising ground-moisture. A house with a traditional foundation may develope moulds and rot, and its very integrity can be put at risk. In the case of a traditional foundation radon gas surging from the soil penetrates and accumulates in the building, creating a serious hazard for human health. Radon gas is a highly radioactive colour- and odorless gas that occurs naturally in the soil. It seeps from the ground into buildings accumulating in the basement and lower floors. Concentrated radon gas in enclosed places is a serious hazard to human health. The international scientific community recognises the inhalation of radon gas as dangerous and it is known to be the second cause of lung cancer after cigarette smoke.
