Passive Vapor Mitigation Systems

Passive Vapor Mitigation Systems rely on building design and materials to block vapor entry. A common approach includes installing a vapor barrier, typically a high-density polyethylene or EVOH membrane, beneath the building foundation. This barrier prevents gases from migrating upward. Passive systems often include venting layers, such as clean gravel with perforated pipes or Lay-Flat Vent, which direct gases to the atmosphere naturally through diffusion. Passive systems require no powered mechanical components, making them cost-effective and low maintenance.
