Radon is a radioactive gas, it is a colourless, odourless naturally occurring and we can’t see, smell, or taste it. This gas is prevalent in granite areas but can occur almost anywhere and all new sites should be checked against the radon potential map for Great Britain to understand the measures required. It is widely held that exposure to high levels of radon can cause lung cancer, Radon produces tiny radioactive particles in the air we breathe from granite that is naturally rich in uranium, but the radon level in the air we breathe outside is very low but can be higher within confined spaces inside buildings. Radon specific membranes are designed to protect structures and inhabitants from the effects of these gasses by forming a barrier and will also act as damp proof membranes for waterproofing and will last the lifetime of the building. With the increase in awareness of such gasses, along with more and more stringent requirements, it is becoming increasingly important for contractors to use ‘’ fit for purpose materials’’ in the secure knowledge that they will perform satisfactorily. The basic radon protection to the structure is by way of a complete ‘’footprint’’ membrane system that when combined with underfloor passive venting (either a radon sump or a ventilated subfloor void) that can be activated with the addition of a fan to offer full radon protection if required. The key to a successful outcome is good installation and attention to the details, even the best membranes poorly installed are likely to fail.
