Understanding Active Soil Depressurization
Active Soil Depressurization (ASD) is the EPA’s recommended standard for radon mitigation — and the method RMS uses to protect commercial and residential buildings across the Southeast.
The Most Effective Radon Mitigation Method Available
Active Soil Depressurization works by creating negative pressure beneath your building’s foundation, drawing radon gas away from the structure before it has a chance to enter occupied spaces.
Testing & Assessment
We start by testing your property to measure radon levels and evaluate your building’s construction type — giving us everything we need to design the right solution.
System Design & Installation
We engineer a custom ASD system for your specific property and install all components with minimal disruption to your building or daily operations.
Verification & Documentation
After installation we test again to confirm the system is working and radon levels are down. You receive full documentation for your records.
Why Active Soil Depressurization Is the Right Choice
ASD is the most widely used and extensively studied radon mitigation method available. When properly designed and installed by a certified contractor, it is effective in virtually every building type and capable of reducing radon levels by up to 99%. RMS has been designing and installing ASD systems for commercial and residential properties across Florida and the Southeast for over 25 years.
ASD is effective across a wide range of property types, including:
