How do you seal radon in a basement?
Sealing the basement floor can help reduce the amount of radon entering the home. But just sealing the cracks would be unlikely to reduce those amounts in the long term. Sealing all cracks and applying non-porous, thick epoxy coatings (over 10 MILS dry film thickness) would be a better step.
