MonoShield Protects Multi-Acre Tampa Logistics Center
Project snapshot highlights:
- Swiftly neutralized vapor threats in a Tampa logistics center
- Met safety and environmental regulatory requirements
A new, expansive logistics center/warehouse building in Tampa, Florida, was the site of a former brownfield where past operations left petroleum hydrocarbons and methane contaminants remaining in soil and groundwater. A cost-effective solution was needed to mitigate the potential vapor intrusion risk from these contaminants. The project team reviewed multiple vapor intrusion mitigation system (VIMS) options, ultimately selecting the MonoShield® Reinforced Metalized Contaminant Vapor Barrier System. MonoShield was viewed as the best available, most cost-efficient technology for the large warehouse considering the site conditions in this fast-moving construction environment. With a foundation approaching a quarter million square feet, and a tight project schedule, MonoShield’s constructability and installation speed separated it from other VI systems considered. Land Science’s technical expertise and support in assisting with the VIMS design were also significant factors in the selection process.
Former Gas Station Developed Into Quick Service Retail

Tackled vapor intrusion risks at a 220,000 square foot cold storage warehouse in Pennsylvania. Combining chlorinated solvents and petroleum hydrocarbons, soil gas contamination threatened future occupants. Working closely with the client, Land Science devised a hybrid solution utilizing Nitra-Seal for office areas and MonoShield for the freezer section. Despite pandemic challenges, the successful installation of these systems ensured compliance with safety and environmental regulations, securing the warehouse for industrial use.
MonoShield Installed at Industrial Warehouse in San Fernando Valley
Project snapshot highlights:
- Prevented vapor intrusion in the warehouse, mitigating risks from groundwater contamination
- Swiftly installed MonoShield, ensuring construction progressed while safeguarding indoor air quality
- Demonstrated proactive environmental mitigation, securing the warehouse in the face of environmental challenges
A new state-of-the-art industrial warehouse facility was constructed in the San Fernando Valley, an area with a history of industrial-related groundwater contamination. The installation was a proactive measure to protect against potential vapor intrusion from soil and groundwater contaminants. The project faced a tight delivery deadline, necessitating a swift yet reliable installation of the vapor barrier.
Retro-Coat Protects Residents at Site of Former NYC Industrial Warehouse
Project snapshot highlights:
- Preemptive solution mitigates potential vapor intrusion threat in New York City
- Retro-Coat provides building residents assurance they are safe from breathing any potential contaminants from prior site uses
- Retro-Coat’s custom finish adds visual appeal to the interior space, enhancing the residents’ living environment
A former 20,000-square-foot industrial warehouse in the Bronx has been transformed into a residence for the community’s housing-insecure population. Based on the property’s history and the surrounding land use, the presence of contaminants such as petroleum hydrocarbons and chlorinated solvents could not be ruled out. Consequently, the developers worked with the City to develop a preemptive solution to mitigate the potential chemical vapor intrusion (VI) concern. Retro-Coat® — a vapor intrusion mitigation system designed as a long-term solution for protecting indoor air in existing buildings — was proposed.
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.
1.2 Million Square Foot MonoShield Barrier Protects Future Tenants at Historic Manufacturing Site
Case study highlights:
- 1.2 million square feet of MonoShield installed in new logistics center
- MonoShield provides advanced chemical protection with a rapid installation process
- Land Science Certified Applicator, MTN, Inc. leverages experience to ensure the investment is protected
On the site of one of the largest former steel mills in the world, a large logistics center redevelopment project is underway. Strategically positioned along the I-95 Corridor, the ongoing development promises to transform the historic site eventually into 15 million square feet of warehousing space. With plans for 20 buildings, the developer is investing $1.6 billion in both the construction and remediation of the once blighted site. The former steel mill site had been impacted by chlorinated solvents and petroleum contaminants in different areas of the property. Therefore, a component of the remediation and redevelopment efforts involves addressing the potential for vapor intrusion (VI). A design engineer was brought onto the team to develop a VI mitigation plan to ensure a safe and healthy environment for future building workers.

- Land Science Certified Applicator, Systems Waterproofing ensured the manufacturer’s specifications were strictly followed
This case study reviews a site where PCE (perchloroethene) was detected in the soil gas beneath a commercial building housing a contemporary art gallery and studio suite in a Los Angeles neighborhood. A Vapor Intrusion Mitigation Plan using Retro-Coat from Land Science was quickly reviewed and approved by LARWQCB.
TerraShield Installation Leads to Development of Animal Welfare Facility
Case study highlights:
- Terra-Shield chosen due to its high chemical resistance
- Successful contaminant vapor intrusion mitigation allows for new state-of-the-art animal center to open to the public
- Installation was seamless due to the use of NitraCore, TerraShield’s spray-applied nitrile-modified asphalt
A local animal welfare organization needed a new building and outdoor space to provide a state-of-the-art center for animal care in an urban community. United Consulting, a multi-disciplinary engineering and environmental consulting firm based in Georgia, was engaged to develop a plan for remediating the soil impacts and assessing vapor intrusion risk at a prospective site. Methane was identified in the vapor phase, requiring mitigation to reduce the vapor intrusion risk. United Consulting specified TerraShield due to its high level of protection against contaminant vapor intrusion. With the building protected from vapor intrusion by TerraShield, the facility workers, prospective pet foster parents, and the animals are ensured a safe breathing environment.
