Retro-Coat® — a vapor intrusion mitigation system designed as a long-term solution for protecting indoor air in existing buildings — was proposed.

MonoShield vapor barrier

MonoShield Protects Warehouse Against Potential Methane Vapor Intrusion

Project snapshot highlights:

  • Easy, fast installation leads to successful implementation during winter conditions
  • Effective implementation in near-freezing temperatures
  • 220,000 square feet of MonoShield installed

A 220,000-square-foot warehouse development in Maryland, located near a former landfill, required contaminant vapor mitigation measures against the potential for methane vapor intrusion (VI). The initial VI mitigation system design proposed a 20-mil plastic membrane with taped seams. While this design met the minimum requirements for VI protection, its implementation during winter posed significant challenges. Cold weather conditions can diminish the workability of taped-barrier systems, leading to significant in-field challenges and project delays. To circumvent these issues and ensure adequate protection against methane VI, the project team sought the expertise of Land Science® for its MonoShield® Reinforced Metalized Contaminant Vapor Barrier and TerraVent Low-Profile Venting System.
