Depressurization System Types

Professional radon mitigation systems for every foundation type in Metro Atlanta

Sub-Slab Depressurization (SSD)

Most common system for slab foundations. Creates negative pressure beneath the slab to prevent radon entry.

Best For:Poured concrete slab foundations
Effectiveness:99% reduction
  • Single or multi-point suction
  • Sealed foundation cracks
  • Below-slab vacuum
  • Minimal disruption

Crawl Space Depressurization

Specialized system for homes with crawl spaces. Uses vapor barriers and suction points to remove radon.

Best For:Crawl space foundations
Effectiveness:95-99% reduction
  • Heavy-duty vapor barrier
  • Multiple suction points
  • Sealed crawl space
  • Improved air quality

Sump Pump Depressurization

Utilizes existing sump pump pit as suction point. Cost-effective solution for homes with sumps.

Best For:Homes with sump pumps
Effectiveness:95-98% reduction
  • Sealed sump lid
  • Integrated system
  • Backup protection
  • Dual functionality

How Depressurization Systems Work

The science behind effective radon reduction in Atlanta homes

The Problem

Radon gas accumulates beneath your foundation due to Atlanta's granite-rich soil. Natural pressure differences and foundation openings allow radon to seep into your home, especially through:

  • Foundation cracks
  • Construction joints
  • Gaps around pipes
  • Crawl space floors
  • Sump pump pits

The Solution

Depressurization systems create negative pressure beneath your foundation, reversing the pressure difference. Radon is drawn away from your home through:

  • Strategic suction points
  • Sealed foundation openings
  • Continuous fan operation
  • Venting above roof line
  • System monitoring

System Components

Suction points (one or more based on home size and radon levels)
PVC piping system (runs from foundation to above roof line)
Radon fan (creates negative pressure beneath foundation)
System monitor (alerts if pressure is lost)
Sealed cracks and openings in foundation
Vapor barrier (for crawl spaces)
Weatherproof exterior housing
Electrical connections with dedicated circuit

Atlanta Foundation Types & Solutions

Expert radon mitigation for every foundation type in Metro Atlanta

Slab-on-Grade

Common in newer Metro Atlanta homes

Recommended Solution:

Sub-slab depressurization (SSD) is most effective. One or more suction points drilled through slab.

Atlanta Consideration:

Atlanta's clay soil requires careful sealing of all foundation cracks.

Crawl Space

Very common in older Atlanta neighborhoods

Recommended Solution:

Crawl space depressurization with heavy vapor barrier installation. Multiple suction points recommended.

Atlanta Consideration:

Georgia's humidity makes vapor barriers essential. Prevents moisture and radon.

Basement

Common in North Metro Atlanta areas

Recommended Solution:

Sub-slab depressurization or drain tile depressurization depending on basement construction.

Atlanta Consideration:

Buckhead, Sandy Springs, and Alpharetta homes often have partial or full basements.

Combination Foundations

Split-level homes in Metro Atlanta

Recommended Solution:

Custom systems combining multiple techniques for different foundation sections.

Atlanta Consideration:

Requires expert design to ensure complete radon reduction throughout home.

Depressurization System FAQs

Common questions about radon mitigation systems in Atlanta

What is sub-slab depressurization and how does it work?

Sub-slab depressurization (SSD) is the most effective radon mitigation method for Atlanta homes with slab foundations. A fan creates negative pressure beneath your foundation, preventing radon from entering your home. Instead, radon is drawn through PVC pipes and vented safely above your roof. It's highly effective, reducing radon levels by 99% in most Metro Atlanta homes.

Which system is best for Atlanta homes with crawl spaces?

Crawl space depressurization is ideal for homes with crawl space foundations, common in older Atlanta neighborhoods. This system installs a heavy-duty vapor barrier across the crawl space floor, sealed at edges and penetrations. Suction points beneath the barrier draw radon out before it can enter your home. This also helps with moisture control in Georgia's humid climate.

Can you use my existing sump pump for radon mitigation?

Yes! Sump pump depressurization is a cost-effective option for Atlanta homes with existing sump pumps. We install a specialized sealed lid on your sump pit with integrated piping to draw radon from beneath your foundation. This method works well and doesn't interfere with your sump pump's drainage function.

How many suction points does my Atlanta home need?

Most Atlanta homes need 1-2 suction points depending on size, radon levels, and foundation type. Larger homes (over 3,000 sq ft) or homes with very high radon levels may require additional points. Our certified professionals conduct diagnostic testing to determine the optimal number and placement of suction points for your specific home.

Will the system damage my foundation?

No. Installation involves minimal drilling (typically 3-4 inch holes) and causes no structural damage. We carefully seal all holes and cracks during installation. For crawl space systems, vapor barriers are installed without foundation alteration. Our technicians follow strict protocols to protect your Atlanta home's foundation.

How long does installation take in Metro Atlanta?

Most sub-slab and crawl space depressurization systems are installed in one day for typical Atlanta homes. Installation time varies by home size, foundation complexity, and system design. Crawl space vapor barrier installations may take 1-2 days. We provide accurate timelines during your free consultation.

What about homes with multiple foundation types?

Many Atlanta homes, especially split-levels, have combination foundations. We design custom radon mitigation systems that address each foundation type. This might combine sub-slab depressurization for slab areas with crawl space systems for other sections. Our expertise ensures complete radon reduction throughout your entire home.
