RadonSeal uses the concrete itself to stop radon by sealing even the microscopic pores deep inside concrete. It does not depend on the reliability of mechanical equipment or the power grid. RadonSeal saves hundreds of dollars on the initial cost of a fan radon mitigation system and much more on operating costs and maintenance. If a fan system is already installed, it will lower its energy losses and reduce the radon level further. By avoiding a noisy radon fan and unsightly piping, RadonSeal protects the resale value of the house.
Moisture causes rebar corrosion and their expansion cracks concrete.
RadonSeal neutralizes the chemicals inside concrete, keeps out water with chemicals, and encapsulates rebar. Paints crack or peel and mastic turns to a white powder. RadonSeal greatly improves adhesion and durability of paints and adhesives. Covering the floor or walls traps water vapor. Moisture accumulates under linoleum, vinyl flooring, carpets or polyethylene sheets.
