A Damp Basement has a Dehumidifier Running Overtime
Scott Razzino’s 26-year-old house in Atlanta has a damp basement. Although he’s directed gutter runoff away from the house and sealed obvious air leaks that would contribute to the problem, he’s still running a 65-pint dehumidifier to keep the moisture levels down.
He’d like to explore other options, and that’s the focus of this week’s Q&A Spotlight.
Among the options he’s quickly given, two broad strategies take shape. The first is tackling the problem from the inside of the basement. Assuming that some moisture is migrating through the concrete block, posters recommend an application of Drylok waterproofing.
Other posters think the application of a waterproofing coat is treating the symptom, not the disease. What’s really needed, they say, is a correctly installed foundation drain that picks up water at the base of the wall and carries it off before it can do any harm.
Although that thinking has become standard fare, not all builders think it’s absolutely necessary. One North Carolina builder is convinced that basement water issues can be solved by handling surface runoff correctly.
