Radon, in gaseous form, as well as its heavy decay products such as polonium and bismuth, collect on dust particles in the air, and are dangerous to human health. These forms of radon, when inhaled, stick to the delicate cells lining the passageways leading into the lungs, causing incidences of lung cancer, as well as general tumor growth in the lungs and respiratory tract. Radon leaks up from underneath foundations and poured concrete, causing occupants in your home to breathe this dangerous element. To protect against this, Mar-flex is introducing a brand new innovation in sealant products, the UltriSeal Radon Block. UltriSeal is a highly efficient sealant that, when applied, protects against radon gas exposure as well as many other harmful chemicals which can seep into your home environment. UltriSeal can be applied to any concrete surface, including concrete walls and driveways. Check out this comprehensive sealant, Mar-flex’s newest innovation in the science of waterproofing.
