Sealing against soil gas entry into the house
If we could create a perfectly sealed barrier between the soil gas and the house, there would be no need for any other radon control measures. But such perfection is yet to be found on a construction site. The better we can seal the radon membrane, the more efficient any other measures will be.
This is the second of four technical radon videos.
