Radon Mitigation Without a Sump Pump - Here's How It Works

In this video, we take a deep dive into the design and engineering behind an advanced radon mitigation system. If your home doesn't have a sump pump or drain tile, chances are you'll need a sub-slab depressurization system like the one we install here. We walk you through the full process step by step, including sealing, pressure field extension testing, stitching, piping, and firestop collar installation. Here’s what we cover: 🔹 Sealing gaps and cracks open to the soil, which is the foundation of any effective radon system 🔹 Pressure field extension (PFE) testing to measure how far and how strong suction travels beneath the slab 🔹 Diagnostic test holes were drilled throughout the home, measured using micromanometers 🔹 Suction point testing with a pitot tube and shop vac to find the ideal spot for fan suction 🔹 Suction pit excavation with about 40 gallons of material removed beneath the floor 🔹 Stitching a trench under the slab to reach isolated areas without adding visible piping 🔹 Vent pipe installation from the storage room through a fire-rated wall into the garage attic 🔹 Firestop collar installation to maintain the fire-rated wall’s integrity 🔹 Radon fan setup using an adjustable-speed fan for optimized performance and energy efficiency 🔹 Final system tuning by adjusting suction based on pressure readings in the test holes ✅ Post-mitigation radon level: 0.4 pCi/L This system was designed for maximum sub-slab coverage with minimal visual impact.
