Mixed-Use Redevelopment Safeguarded with TerraShield
Project highlights:
- Over 30,000 Square Feet of TerraShield Installed
- Development protected from potential chlorinated VOC vapor intrusion
- Passive SSDS installed utilizing TerraVent, a low-profile passive venting system
Environmental assessments for a Northern Michigan redevelopment project identified residual volatile organic compounds (VOCs)—primarily perchloroethylene (PCE), trichloroethylene (TCE), and dichloroethylene (DCE)—within subsurface soils and groundwater on land slated for a downtown redevelopment initiative. The potential for vapor intrusion prompted the development team to integrate a proven vapor mitigation system into the new construction design.

- Fast installation by certified applicators ensured regulatory compliance and kept the project on schedule.
A newly constructed youth development center in the Mid-Atlantic region required a vapor intrusion mitigation solution to safeguard children, families, and staff from potential subsurface vapor intrusion. The site’s urban history carried the potential for vapor intrusion from chlorinated volatile organic compounds (cVOCs) present in underlying soil and groundwater. To ensure occupant protection and regulatory compliance without delaying construction, the project team selected Nitra-Seal, Land Science’s advanced nitrile composite vapor barrier system.

Construction Quality Control during VIMS Installation
In this webinar Sigrida Reinis, PhD, PE, Senior Associate at Langan Engineering and Environmental Services Inc., discussed construction quality control during vapor intrusion mitigation system (VIMS) installation. She was joined by Nick Mjolsness, Senior Technical Sales Manager at Land Science, who discussed construction quality control best practices for installation of Land Science vapor barriers.
Highlights of this webinar:
- Case studies of projects illustrating the importance of quality construction assurance (CQA)
- Critical role of regular field visits by the VIMS designer and a practical framework for CQA field visits
- CQA best practices when installing contaminant vapor barrier systems from Land Science
When post-construction indoor air monitoring indicates that there is a potential gas/vapor intrusion (VI) condition, all eyes turn to the engineer that designed the vapor intrusion mitigation system (VIMS). It is therefore incumbent upon the design professional to not only design a well-functioning VIMS but also to prepare and implement a robust quality assurance program, which typically begins with the preparation of a Construction Quality Assurance Plan (CQAP). Even then, the importance of regular field visits to observe the installation of the VIMS components cannot be overstated. This presentation will provide a series of examples from completed projects that illustrate a variety of failures and near-misses, ranging from poor design choices to contractor errors that resulted in or had the potential to result in sub-par VIMS performance. The examples presented not only reinforce the importance of regular field visits by the VIMS designer but also provide a practical framework for CQA field visits.
