Technology in Reducing Radon
- Current radon mitigation technology has developed reliable, proven techniques for reducing radon levels in virtually any home and property, including new construction.
- Radon mitigation systems create a closed path (via PVC pipe) for radon gas to follow from entry at concrete slab to exit above roofline.
- A radon fan operates 24/7/365 to pull radon gas from below concrete slab through PVC piping to exit the top and outside where it dissipates outside and no longer in your home.
- Radon mitigation system installation should be installed in accordance with the state license/certification standards or guidance. The EPA recommends hiring a radon abatement service certified by either the National Radon Proficiency Program or the National Radon Safety Board (NRSB). See "About Us" for our certified credentials.
Key Approaches to a Radon Mitigation System
Depends on home structure and property. Typical home radon mitigation techniques include: Active-slab depressurization system (ASD), and Sub-membrane depressurization (SMD) for dirt crawlspaces.
Active-Slab Depressurization (ASD)
- ASD is the most common method of radon remediation. About 95% of homes in the greater Washington, DC region have this type of system. An ASD system includes a radon fan which runs continuously to depressurize the area under a home's concrete slab and expels it outside via exhaust where it quickly dissipates. Radon gas exhaust is configured to meet all National Radon Safety Board Standards (NRSB). ASD is the most effective and reliable radon reduction approach used by radon mitigation system installers.
- Used for properties built with a basement and slab-on-grade homes. It is the primary system for homes which also include a crawlspace.
Exterior Radon Mitigation Systems
Interior - Drill in Basement to Access Radon Gas
Interior - Sump Lid Access to Radon Gas
Sub-Membrane Depressurization (SMD)
- Preferred mitigation method for crawlspace is to depressurize floor space by using a high-density polyethylene vapor barrier laid on soil. Seams are sealed and edges are sealed to the foundation wall. A perforated pipe is placed beneath vapor barrier and connects to radon fan. This will depressurize the area under vapor barrier that requires radon remediation, directing radon gas to discharge outside a home exhaust vent per code.
- For properties with crawlspace-only or crawlspace in addition to a basement.
Specific Elements of Certified Radon Mitigation Systems:
- Process includes sealing cracks/openings in unfinished basement areas, and sump cover lids to prevent loss of vacuum pressure.
- Depending on property, radon fans are located by code in attic, outside mounted on exterior of property, or in a garage attic.
- Installation includes a tubing indicator (manometer gauge) located in a prominent location near entry point of pipe for occupant to easily view system is functioning properly.
- Power to radon fan is in accordance with local electric codes.
- All portions of the system are to be labeled and include a simple instruction manual sheet, with warranties provided to the homeowner.
- New radon mitigation systems should be retested no sooner than 48 hours (no later than 30 days) after installation to verify reduction. EPA recommends testing every two years.
- Radon mitigation system cost depends on the property. In Northern Virginia its typically $800 – $1500.
Safety and Work Environment
As an environmental specialist, Boulder Edge takes seriously and understands the significance our role plays as we daily focus on minimizing risk for our customers by mitigating radon gas. Mitigating radon gas is an important health related issue, yet secondary to the Novel Coronavirus (COVID-19) Pandemic.
Boulder Edge (BEI) customarily implements Radon Mitigation Standards (RMS), Occupational Safety and Health Administration (OSHA) standards (equipped with air-quality, dust control, electrical, chemical protection) which includes Personal Protective Equipment (PPE) as an essential safety component of our service.
Due to the (COVID-19) pandemic, our PPE safety measures added social-distancing upon arrival and through installation process inside and outside a home, with contact-less payment onsite.
Our code-compliant procedure includes following all single-family building codes regarding penetrating any firewall and re-supporting any structural bearing box joist.
All electrical work should meet or exceed local codes. The glues, solvents and materials that are used may be hazardous. You should not be in the work area during the installation. Material Safety Data Sheets (MSDS) will be supplied upon written request.
While work is in progress the windows will be opened and portable ventilation systems may be used. Workers should wear proper clothing suitable for this type of work, and wear eye, ear, and respiratory protection when necessary. Workers should be monitored for radon exposure during the work.
