Just like wood, concrete should be preserved with a sealer. As concrete ages, it becomes more porous. Any exterior coating deteriorates under the attack of chemicals from inside the concrete. RadonSeal stops water seepage even against hydrostatic pressure. The pores in concrete let in water vapor and their capillary action draws in water from the soil, which evaporates.
High humidity promotes molds, mildew, biological contaminants, and a musty smell.
Paint or surface sealers crack or peel and cannot stop dampness. Dehumidifiers consume lots of power and pull in more moisture through the concrete, speeding up its deterioration. RadonSeal reduces dampness in the whole house. Moisture also carries dissolved radon indoors. RadonSeal uses the concrete itself to stop radon by sealing even the microscopic pores deep inside concrete.
