Sub-slab depressurization is a technique where a fan creates suction beneath a concrete floor to draw out soil gases like radon before they can enter a building. It's commonly installed during new construction or retrofitted in crawl spaces, using a network of pipes in the gravel layer to pull vapors from below the slab and vent them safely outside. The system works continuously, often with a manometer to show it's running properly.
