Featured Case Study | MonoShield Protects Warehouse Against Potential Methane Vapor Intrusion 

A large warehouse development 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.

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

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.

Featured Case Study | 1.2 Million Square Foot MonoShield Application Protects Historic Steel Manufacturing Site 

On the site of one of the largest former steel mills in the world, a large logistics center redevelopment project is underway. The development promises to transform the historic site into 15 million square feet of warehousing space and bring the community anywhere from 5,000 to 10,000 new jobs. Working with the environmental consultant and the developer, Land Science was chosen to incorporate the MonoShield contaminant vapor barrier system to preemptively address any potential vapor intrusion issues.

Technical Data Sheet | One of the Fastest Vapor Barriers to Install is Also One of the Safest 

MonoShield is a single-layer, underslab contaminant vapor barrier offering superior chemical resistance, durability, and ease of installation versus traditional sheet membranes. MonoShield is an optimal mitigation solution to reduce liability for large, slab-on-grade buildings where installation speed is critical, for sites with a low-level vapor intrusion (VI) risk, or for use in conjunction with active sub-slab venting systems.

eBook | 5 Reasons to Consider a Preemptive Vapor Barrier System to Protect Your Property Investment 

Historically, easily punctured thin-mil plastic sheets or inflexible and difficult-to-seal High-Density Polyethylene (HDPE) Barriers were the only option for vapor mitigation at large warehouses or sites where regulatory requirements were not a driving risk factor. These solutions offered either chemical resistance or constructability, but not both. Composed of an innovative metalized film, MonoShield sets the standard for preventing diffusion and permeation of chemical vapors.

Case Study | Retro-Coat Protects Los Angeles Contemporary Art Gallery 

PCE was detected in the soil gas beneath a commercial building housing a contemporary art gallery and studio suite in a Los Angeles neighborhood. Investigations revealed that a regional groundwater contaminant plume, originating from an upgradient source, was the cause of PCE in the soil vapor, and indoor air sampling results showed that the intrusion of PCE-impacted soil vapor to the indoor air was a complete exposure pathway for on-site workers. As a result, a mitigation plan was required to protect against potential VI exposure to PCE. The contaminant vapor barrier selected for implementation was Retro-Coat, a low-permeability, epoxy coating system proven effective at preventing VI of volatile organic compounds like PCE and a favorable choice for existing structures.

MonoShield warehouse application

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.

Retro-Coat

Retro-Coat Protects Los Angeles Contemporary Art Gallery

Case study highlights:

  • Retro-Coat Vapor Intrusion Coating System application achieved compliance with the Los Angeles Regional Water Quality Control Board (LARWQCB) standards for VI mitigation
  • Retro-Coat chosen as a low-cost mitigation solution with outstanding chemical resistance that provides aesthetic value to a building’s interior space
  • 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.

Featured Video | TerraShield Effectively Protects Future Residents from Contaminant Vapor Intrusion 

This video features a former industrial site in Lansing, Michigan, where a multi-family and senior residence community were being developed. Soil and groundwater were contaminated as a result of historic activities including chrome plating, underground storage tanks, automotive repair, a junkyard, and welding operations. TerraShield was chosen to mitigate potential vapor intrusion, offering the highest level of chemical resistance available on the market today, providing protection against vapor intrusion risk from contaminants like petroleum and Trichloroethylene (TCE). Installing TerraShield ensures the safety of indoor air for future residents of the development while meeting the regulatory requirements of the Michigan Department of Environment, Great Lakes, and Energy (EGLE).

Project Snapshot| MonoShield Installed Faster and at a Significantly Lower Cost than System with Taped Seams

Sawyer Yards is an apartment community located in Houston’s vibrant Arts District neighborhood. Chlorinated solvents were detected in soil gas, posing a potential vapor intrusion risk to future residents. The original vapor mitigation system (VMS) specification called for a single-layer barrier with taped seams. However, the building’s foundation contained many utility penetrations and terminations, requiring numerous taped seams. These taped seams significantly reduce application efficiency and ultimately result in potential barrier weak points. In contrast, MonoShield® incorporates a spray-applied nitrile-advanced asphalt latex, offering superior application efficiency with unmatched chemical resistance.
