What is sub-slab depressurization?
Sub-Slab Depressurization (SSD, sometimes called ASD for Active Sub-Slab Depressurization) creates a small vacuum beneath your concrete slab. That vacuum reverses the natural pressure gradient that pulls radon into your home, safely venting soil gas above the roofline before it ever enters your living space.
Why it's ideal for Boca Raton homes
Nearly every home in Boca Raton is built on a concrete slab. That makes SSD the fastest, cleanest, and most cost-effective mitigation approach. No crawl space work, no interior wall damage, and no visible interior pipe in most cases.
- Guaranteed radon reduction below 4.0 pCi/L
- Whisper-quiet operation (35–45 dB, quieter than a refrigerator)
- Low energy consumption — typically under $8/month to run
- Discreet exterior pipe run, painted to match your home
- 20-year expected fan lifespan under Florida operating conditions
Design considerations
Not every slab is created equal. Post-tension slabs, monolithic pours, homes with sub-slab plumbing, and additions with mismatched foundations all require different suction-point strategies. Our certified mitigation specialists perform a diagnostic vacuum test before finalizing your system design to guarantee performance.
