|RADON REDUCTION SYSTEMS
We utilize the two most common and effective active radon mitigation methods, Sub-Slab Depressurization (SSD) and Sub-Membrane Depressurization (SMD) depending on the the project.
Regardless of the method, we custom tailor each Radon Reduction System to meet the unique specifications and requirements for each project. No two projects are ever alike.
At the onset of each project we analyze your requirements and design a system that maximizes radon reduction, minimizes inconvenience, adheres to the aesthetics of the property, while enhancing your homes value.
Sub-Slab Depressurization (SSD) Systems
This method uses a specialized radon exhaust system to reduce the pressure below the floor slab so that the air between the building substructure and the soil flows out of rather than into the building. This method is often used in basements.
Radon is exhausted out and up through a PVC pipe, exiting above the highest eave of the structure. Discharging the exhaust above the highest eave ensures dilution of the exhaust to outdoor air and minimizes risk of radon entering the structure.
Additionally, exhaust outlets are installed as close to the roof ridge line as possible,10 feet or more away from doors, windows or other openings in the building, and 10 feet or more from any openings in nearby structures.
Sub-Membrane Depressurization (SMD) System
This method is required for crawl spaces and other areas where the slab is in direct contact with the rock and soil. With the SMD method, a plastic sheet (Polyethylene or similar) is permanently installed over exposed rock and soil. A fan is then installed to create suction under the plastic sheeting, drawing the vapors out from the soil into a PVC pipe, then safely exhausted away from the home, minimizing vapors from entering ambient indoor air, similar to the SSD method.
