TerraShield Protects Future Occupants from Harmful Vapor Intrusion Making Way for Development of Auto Manufacturer’s HQ

A large automotive and supply company planned to build its new corporate headquarters on a 4.5-acre brownfield site recently acquired in Southfield, MI. Soil and groundwater sampling on the property revealed the presence of trichloroethylene (TCE) and polynuclear aromatic hydrocarbons (PAHs). TCE was also identified in soil gas beneath the site. Within the footprint of the planned building itself, contaminant concentrations were found to be in excess of applicable indoor air quality screening levels. Recognizing the unique characteristics of the site as well as the significant levels of contamination present, Envirologic centered their vapor mitigation strategy on the installation of TerraShield Aluminum Nitrile Vapor Barrier with fan-assisted sub-slab ventilation.

 

 

TerraShield Provides the Highest Level of Protection Against Contaminant Vapor Intrusion

When developing properties on sites with known environmental impacts, one of the biggest issues is the risk to human health. Failure to address these issues can result in adverse health effects and millions of dollars in legal exposure. TerraShield was designed specifically to eliminate risk of exposure by employing innovative technologies to provide best-in-class chemical resistance and durability. TerraShield offers a higher level of protection compared to any vapor barrier system available today. With industry- leading standards for installation along with robust warranty options, there is simply no better option on the market for industrial, commercial, or residential vapor intrusion mitigation. Watch the video to learn more about TerraShield.

Superior Chemical Resistance Over Any Vapor Barrier On The Market Today

TerraShield is a significant step forward for vapor intrusion barriers. Employing an innovative dual-metallized film technology in combination with a versatile spray-applied nitrile core, TerraShield provides superior chemical resistance over any existing vapor barrier currently on the market.

Nitra-Seal Applied as Preemptive Vapor Mitigation Solution for National Restaurant Chain

National quick-service restaurant chains are looking for creative, efficient, and cost-effective ways to redevelop brownfield properties. This project development site is a newly opened quick-service restaurant in Conyers, Georgia. Offsite chemical spills from historical operations had resulted in low-level volatile organic compounds (VOCs) released to the subsurface, creating a potential for vapors to intrude into new buildings constructed in the affected area. Recognizing the risk and placing emphasis on future workers’ safety, the forward-thinking client decided that a preemptive measure be instituted, requiring the installation of a vapor mitigation system as part of the construction specification.

A Proven Vapor Barrier System Now Improved With Nitrile

Nitra-Seal® is a new advanced nitrile composite barrier system. It represents an update/improvement on current vapor barrier systems. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene Rubber (SBR) latex/asphalt is used. Nitra-Seal offers a substantial upgrade as it employs a more chemically resistant nitrile latex instead of the more susceptible SBR latex. Nitra-Seal is a composite system creating the ideal blend between constructability and chemical resistance by using both high density polyethylene (HDPE) and nitrile-advanced, spray-applied asphalt core.

Ease of Installation Saves Time and Money for Preemptive Solution To Mitigate Potential Gasoline Vapors

This project snapshot features the following:

  • Nitra-Seal protects future restaurant workers and guests
  • Former Gas Station

Property developers for a national restaurant chain planned a new restaurant building on an old gas station in Galveston, Texas. It is common practice in the retail restaurant industry that when confronted with building a restaurant on a former gas station, the property developers will specify a vapor mitigation system (VMS) into the construction plan. The VMS serves as a preemptive measure to address gasoline contaminants that might have escaped detection during the site closure process. In these instances, the property developers require that the vapor mitigation system installation be completed efficiently and at a competitive cost while providing comparable or better chemical resistance. After evaluating VMS options, the property development team specified Nitra-Seal as the technology best suited for this purpose. According to the Land Science certified applicator, in comparing their experience installing generic styrene-butadiene-rubber asphalt emulsions, Nitra-Seal’s spray-applied nitrile-advanced asphalt latex core material was easier to apply and cured more rapidly. This saved time and money for the VMS installation, improving the project’s overall construction efficiency, and enabling the restaurant to proceed toward its opening.

Leading Hotel Chain Moves Forward with Brownfield Site Construction Following Installation of Vapor Barrier System

This project snapshot features the following:

  • Hotel Brand Expansion Into New Market
  • TerraShield Protects Guests and Employees at Hotel
  • 20,000+ Square Feet Installed

The project site is a modern, climate-controlled self-storage facility that includes all-in-one moving, packing, and storage services for its customers. The building was developed on a former industrial brownfield at the site of a former factory. As part of Maryland’s Voluntary Cleanup Program, the environmental consultant completed a Phase II investigation, finding elevated chlorinated solvent contaminants in the soil gas. The Maryland Department of Environment required the installation of a vapor mitigation system over a portion of the building. However, in working with the consultant, it was ultimately determined that a vapor barrier spanning the entire building footprint would be necessary to protect the future building tenants fully. Based on chlorinated solvent concentrations, TerraShield® was specified to provide the highest level of chemical resistance and long-term barrier performance available on the market. The project required active venting and a site-specific design, leveraging Land Science’s vapor barrier design expertise. Additionally, the TerraShield vapor mitigation system included an extended material warranty to provide the project stakeholders added assurance that building occupants would be protected long into the future.

Future Retail Tenants Can Breathe Easier Knowing That Vapors Will Not Intrude

This project snapshot features the following:

  • Former Dry Cleaning Operations Transformed Into Safe Retail Storefront Property
  • TerraShield with Retro-Coat Complete Remediation Efforts
  • First Installation in Los Angeles County

The first TerraShield installation completed in Los Angeles County is a former dry cleaning site redeveloped to make way for a retail storefront. Chlorinated solvents and benzene were present in the subsurface left by past site activities requiring ongoing active remediation over a several year period. The Los Angeles Regional Water Quality Control Board oversaw the site remediation efforts, which included soil excavation and operation of a soil vapor extraction system to remove the majority of the contaminants. Although these efforts effectively removed most of the contamination, lower concentrations remained in the soil gas, prompting the need for a vapor mitigation solution. The environmental consultant and their client chose TerraShield® to provide the maximum protection available to protect future retail tenants from potential exposure to harmful chlorinated solvent and benzene vapors. TerraShield was installed at grade, terminating at a concrete slab in the building that remained following soil excavation activities. Retro-Coat™, a chemical-resistant surface coating effective in mitigating vapor intrusion, was also applied to the existing concrete slab and used as a finished floor surface.
