Sub-slab depressurization is a technique used in homes with radon problems. A pipe is inserted through the concrete floor into the gravel beneath, and a small fan gently sucks air from under the slab. This creates a slight vacuum that pulls radon-laden soil gas away from the house, venting it safely outside. It's a quiet, effective system that runs continuously, keeping indoor air healthier without needing major renovations.
