What is sub-slab depressurization system?

A sub-slab depressurization system consists of PVC piping installed through the slab floor and a fan connected with the piping. A subsurface depressurization system prevents vapor intrusion by directing hazardous vapors in the soil to the exterior of the building.

How effective is sub-slab depressurization?

Sub-slab depressurization system can reduce indoor radon levels by 80 to 99+%.

What is sub-slab vent?

Components. Passive sub-slab venting systems for new construction consist of a network of horizontal vent piping surrounded by a layer of permeable fill material below the concrete slab or foundation of a building.

What is active sub-slab suction?

Active Subslab Suction (also called active mitigation system) is the most common and usually the most reliable Radon reduction method. Suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the house.

What is a vapor mitigation system?

Vapor intrusion mitigation systems are installed to reduce health risks in buildings where chemical vapors from contaminated soil and groundwater may be inhaled by indoor occupants. They also may be installed as a precaution where vapor intrusion might occur in the future.

Will a vapor barrier reduce radon?

A vapor barrier itself is designed to resist the flow of air. A crawl space vapor barrier system also has been known to slow the movement of harmful gases like radon from infiltrating the soil, helping the crawl space vapor barrier system greatly reduce the levels of radon found in the home.

Do air purifiers help with radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.
