Radon Mitigation in Champaign, IL

How sub-slab depressurization works

The most effective radon system is active sub-slab depressurization (SSD). We create a suction point through your basement slab, then run piping to an inline radon fan mounted in the attic or on an exterior wall. The fan pulls radon-laden air from the soil beneath your foundation — before it enters your living space — and vents it safely above the roofline. Because it depressurizes the soil under the whole slab, it addresses the source rather than chasing cracks.

For homes with sump pits, crawl spaces, or drain tile, we adapt the design — sealing sump covers, adding sub-membrane depressurization, or tying into existing drain tile.

What a typical project looks like

• Assessment — confirm your reading and inspect foundation, sump, and layout.
• Design — suction points, fan sizing, cleanest pipe routing.
• Installation — most systems done in a single day.
• Sealing — major cracks and the sump cover, to maximize performance.
• Post-test — re-test after 24+ hours to confirm you're below 4.0 pCi/L, in writing.
