In the modern building sector, a radon mitigation system is always more requested, as this kind of gas is very dangerous for our health. The radon is a radioactive gas that is naturally present in the subsoil: if we are outdoor its presence is inoffensive but it becomes dangerous when we are in a closed space without an adequate ventilation. For this reason it is important that, especially in the foundation, the ventilation is ensured, in order to bring out the radon. Geoplast offers a wide range of products to create ventilated foundations in many fields: residential, industrial or prefabricated buildings, schools and also in case of renovation of existing buildings. Modulo, Minimodulo, Multimodulo and New Elevetor are plastic formworks that can be used to build an efficient radon mitigation system. They are made of polypropylene, a recyclable material, resistant, light and easy to place. Thanks to their technical characteristics they ensure a good ventilation, even with a little thickness.
