- • Foundation cracks: Settling over time creates pathways for radon gas
- • Sump pump pits: Direct opening to soil beneath your home
- • Construction joints: Gaps where walls meet floors
- • Utility penetrations: Pipes and cables entering through foundation
- • Crawl spaces: Dirt floors allow continuous radon entry
