Radon Mitigation FAQ

Types of Radon Mitigation Systems

Sub-Slab Depressurization (SSD)

Sub-slab depressurization works by creating a pressure differential between the soil beneath a building’s foundation and the indoor environment. This technique involves the following key steps:

Installation of a Mitigation System: A specialized radon mitigation system is installed. The central component of this system is a PVC pipe that runs from the ground beneath the building (below the concrete slab) up through the structure and out through the roof or exterior wall.

Sub-Slab Depressurization: A fan, known as a radon mitigation fan or radon fan, is installed in the PVC pipe. This fan creates a negative pressure or vacuum beneath the building’s foundation, drawing radon gas from the soil into the pipe. As the radon-laden air is pulled away from the soil, it is safely vented above the roofline or to the exterior, where it dissipates harmlessly into the atmosphere.

Sealing Entry Points: Any openings or cracks in the foundation that may be allowing radon entry are sealed to prevent further radon infiltration.

Monitoring and Verification: After installation, the system is typically monitored to ensure it is effectively reducing radon levels to acceptable levels. Periodic testing may be conducted to confirm the system’s continued efficiency.

Sub-slab depressurization is considered one of the most reliable and effective methods for radon mitigation. It is often the preferred choice because it actively removes radon gas at its source, preventing it from entering indoor living spaces. This method can be customized to suit different building types and configurations, making it adaptable to various construction designs.

Sub-membrane depressurization (SMD)

Sub-membrane depressurization (SMD) is another effective technique used in radon mitigation to reduce elevated radon levels in buildings. Similar to Sub-Slab Depressurization (SSD), SMD is designed to prevent radon gas from entering indoor living spaces by creating a pressure differential. However, SMD is specifically used in crawl spaces or areas with dirt or gravel floors covered by a plastic membrane or vapor barrier.

Here’s how Sub-Membrane Depressurization works:

Installation of a Mitigation System: A specialized radon mitigation system is installed in the crawl space area. The central component of this system is a PVC or similar pipe that is placed beneath the plastic membrane or vapor barrier.

Sub-Membrane Depressurization: A fan, known as a radon mitigation fan or radon fan, is installed in the pipe beneath the membrane. This fan creates a negative pressure or vacuum between the plastic membrane and the soil or gravel underneath it. As a result, radon gas that might otherwise migrate through the soil and into the crawl space is drawn into the pipe beneath the membrane.

Ventilation and Discharge: The radon-laden air collected beneath the membrane is safely vented to the outdoors, either through the roof or an exterior wall. This allows the radon gas to dissipate harmlessly into the atmosphere.

Monitoring and Verification: After installation, the system is typically monitored to ensure it is effectively reducing radon levels in the crawl space to acceptable levels. Periodic testing may be conducted to confirm the system’s continued efficiency.

Sub-membrane depressurization is particularly suitable for crawl spaces with dirt or gravel floors that are covered by a plastic vapor barrier or membrane. It is designed to address radon issues in these specific areas and is considered an effective method to prevent radon from entering the building’s living spaces.

Sump/Drain-Tile Depressurization (DTD)

Sump and drain-tile depressurization is a radon mitigation technique used to reduce elevated levels of radon gas in buildings, particularly in basements or crawl spaces. Radon is a colorless, odorless, and radioactive gas that can seep into homes and buildings through the soil and foundation. Prolonged exposure to high levels of radon can increase the risk of lung cancer.

Here’s how sump and drain-tile depressurization works:

Sump Pump: Many homes have sump pumps installed in their basements or crawl spaces to prevent water buildup and flooding. A sump pump collects excess groundwater and pumps it out of the building. In a sump and drain-tile depressurization system, the sump pump pit is used as part of the mitigation system.

Perforated Drain Tile: Perforated drain tiles are pipes with small holes or perforations designed to collect water from the surrounding soil. These drain tiles are typically installed around the perimeter of the basement or under the basement floor. They help manage excess water and moisture.

PVC Pipe and Ventilation: In a sump and drain-tile depressurization system, a PVC pipe is connected to the sump pump pit and/or the perforated drain tiles. The pipe is routed to the exterior of the building, usually through the roof or an exterior wall. An exhaust fan or blower is installed in the PVC pipe to create a negative pressure or suction in the soil beneath the building.

Radon Gas Removal: As the fan or blower operates, it draws air and soil gases, including radon, from beneath the building’s foundation. This prevents radon from entering the living space and instead directs it safely outside, where it quickly dilutes in the outdoor air and poses no health risk.

By creating this depressurized zone beneath the building, the sump and drain-tile depressurization system effectively reduces the entry of radon gas into the indoor environment. It’s an effective and commonly used radon mitigation method, especially in areas where elevated radon levels are prevalent in the soil.

Heat Recovery Ventilators (HRV)

We have installed many direct ventilation systems where the standard mitigation system listed above is unavailable. Sometimes it is more cost-effective to install an HRV where other mitigation methods can get expensive.

A Heat Recovery Ventilator (HRV) is a mechanical ventilation system designed to improve indoor air quality in buildings while also conserving energy. HRVs are commonly used in residential and commercial buildings to provide controlled ventilation by exchanging stale indoor air with fresh outdoor air. They are particularly useful in buildings with good insulation and airtight construction to ensure proper ventilation without excessive heat or energy loss.

Here’s how an HRV works:

Supply and Exhaust Airflow: HRVs consist of two separate air duct systems—one for supplying fresh outdoor air into the building and another for exhausting stale indoor air from the building. These airflows run parallel but do not mix.

Heat Exchange Core: At the heart of the HRV is a heat exchange core, typically made of materials with high thermal conductivity, such as aluminum or plastic. This core allows heat to transfer between the incoming and outgoing air streams without them mixing. In cold weather, heat from the indoor air is transferred to the incoming cold outdoor air, pre-warming it. In hot weather, the process is reversed, where heat from the incoming outdoor air is transferred to the outgoing indoor air, helping to cool it.

Fans and Filters: HRVs are equipped with fans that ensure a controlled and balanced airflow between the two air streams. Filters are also commonly used to capture dust, pollen, and other airborne particles from both incoming and outgoing air, improving indoor air quality.

Controls: HRVs are typically equipped with controls that allow users to adjust the ventilation rate and other settings to meet the specific needs of the building and its occupants. Some HRVs come with smart features that can automatically adjust ventilation based on factors like humidity or occupancy.

Benefits of HRVs:

Improved Indoor Air Quality: HRVs ensure a steady supply of fresh outdoor air, reducing the buildup of indoor pollutants, humidity, and odors.

Energy Efficiency: By recovering heat from exhaust air, HRVs help to conserve energy and reduce heating and cooling costs.

Comfort: HRVs maintain a more consistent indoor temperature and humidity level while providing fresh air, contributing to occupant comfort.

Moisture Control: HRVs help control indoor humidity levels, which can prevent issues like mold growth.

HRVs are an effective solution for providing controlled ventilation and maintaining indoor air quality while minimizing energy loss, making them a valuable component of modern energy-efficient building designs.
