The Core Engineering Method for Radon Reduction
Sub-slab depressurization (SSD) is the primary engineering approach for reducing radon in slab-on-grade and basement homes. The system creates negative pressure beneath the slab so soil gas is captured and vented before entering living space.
How SSD Works
- Suction point creation: Access beneath slab for controlled pressure field development.
- Piping configuration: Route gas collection line to exterior vent stack.
- Radon fan installation: Maintain continuous sub-slab negative pressure.
- Post-install verification: Confirm radon reduction via follow-up testing.
Boise Installation Considerations
- Foundation geometry: Basement vs slab layout influences suction strategy.
- Sub-slab permeability: Soil characteristics affect pressure field reach and fan sizing.
- System routing: Vent placement and line configuration balance performance and aesthetics.
When SSD Is Paired With Other Work
Radon mitigation often overlaps with crawlspace and moisture projects. We coordinate SSD with radon testing/mitigation planning and crawlspace controls when applicable.
