I'm planning to finish my basement. House is about eight years old. It has poured concrete foundation walls. There are no water problems, but I'm thinking about applying Drylock waterproofing (latex-based) on the walls, and also sealing the concrete floor. My hope is that it might help reduce radon vapors, albeit just slightly. The last tested level is about 3 which below the action level, but I'd like to reduce it even further.
Any one know if sealing the floor and Drylock'ing the walls would help reduce radon? Or is it a waste of time and money?

Radon gas can enter a house from many different areas. Sealing your foundation cracks and openings can help bring the level of gas entering down, but will not necessarily lower the amount of radon in a home.
Check your water source radon levels too.
(For the sake of other readers of this post: such an action WILL NOT STOP RADON GAS, and is NOT A STANDARD RADON GAS MITIGATION TECHNIQUE).
