Mitigation Systems
Complete active sub-slab depressurization (SSD/ASD) and sub-membrane depressurization (SMD) systems achieving 80–99% radon reduction. Includes soil gas collection networks, suction sumps, and radon extraction systems for existing buildings. The most effective and widely used radon reduction method, recommended by EPA and international building codes.
Application
Intervention Type
Active sub-slab depressurization (SSD/ASD) is the most effective radon reduction method, routinely achieving 80–99% reductions. These complete systems create negative pressure beneath building slabs, preventing radon entry and venting it safely above the roofline.
