Floor covering or finishing the basement traps moisture. Humidity promotes molds, mildew, and a musty odor, which circulate through the building. Concrete paints or surface sealers are porous or crack and blister, and cannot stop water vapor. Power-hungry dehumidifiers pull in more moisture through the concrete, speeding up its deterioration. RadonSeal reduces vapor transmission and dampness in the house.
Water also carries dissolved radon indoors.
It saves hundreds of dollars on the cost of a fan radon mitigation system and even more on annual operation and maintenance. If a fan system is already installed, it reduces the radon level further and lowers its energy losses. RadonSeal does not depend on the reliability of mechanical equipment or the grid. By avoiding unsightly piping and the often noisy radon fan, RadonSeal protects the resale value of the house. Corrosion and expansion of rebar causes cracks.
