How To Seal Cracks In Basement Floor For Radon

Defend your family from the dangerous gas, radon, by sealing the cracks in your basement floor. Radon is a naturally occurring gas that can seep into your home through cracks in the floor or walls and lead to serious health problems, including lung cancer. But, you can take action by locating and sealing the cracks.

Start by searching for cracks in the floor and walls of your basement using a flashlight. Identify all the thin lines or cracks and prepare to seal them.

Seal the cracks with a concrete patching compound designed specifically for basement use. These compounds feature special additives to form an airtight seal. Clean the area surrounding the crack and apply the compound with a putty knife or trowel, filling in any gaps and covering the entire crack with a thin layer. Smooth out any bumps or irregularities with a wet rag after the compound dries.

Allow the patching compound to cure for 24 hours, then test for radon levels. If levels remain high, add extra layers of the patching compound until you achieve a safe level.

Protect your home and family from radon exposure by sealing the basement floor cracks. With proper preparation and the right patching compound, you can maintain a safe and healthy living environment.
