Nitra-Seal Applied as Preemptive Vapor Mitigation Solution

 

A growing community near Charlotte, North Carolina was seeking a site to construct a new town hall and public library complex. The city planners had identified a land parcel that would meet the spatial requirements for the new complex, but the site was a former gasoline service station which operated on a portion of the land for nearly two decades. As part of the City’s due diligence, a Phase I Environmental Site Assessment (ESA) was completed and revealed the underground storage tank (UST) system was decommissioned in 1991 with the tanks abandoned in place. However, no records existed which documented environmental conditions at the time of UST removal. Consequently, the USTs were listed as a recognized environmental concern (REC) in the Phase I ESA. In early 2020, a geotechnical investigation identified soil with odors and elevated photoionization detector (PID) readings, a further indication of petroleum hydrocarbon (PHC) contamination in the subsurface.


Introducing a New Advanced Nitrile Composite Vapor Barrier System

Nitra-Seal is an update/improvement on current vapor barrier systems. Originally, passive vapor barrier systems were waterproofing systems adapted for use as contaminant vapor barriers. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene (SBR)- modified asphalt is used. While excellent at repelling water, aggressive chemicals such as petroleum solvents and chlorinated volatile organic compounds (VOCs), will permeate into the SBR-modified asphalt at a relatively high rate particularly in sensitive areas of the building construction such as barrier seams, slab penetrations and perimeters. Nitra-Seal offers a substantial upgrade as it employs a more chemically resistant nitrile latex instead of the more susceptible SBR material. Nitrile is recognized throughout the environmental engineering industry as being more chemically resistant than rubber or SBR and is often used in personal protective equipment when working on hazardous waste sites (e.g. nitrile gloves).

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.

Featured Project Snapshot: Townhome Residents Protected from Exposure to Vapors

 

Townhome Residents Protected from Exposure to Vapors

 

A townhome development in Greenville, South Carolina, implemented the MonoShield vapor barrier and TerraVent low-profile venting system to address low-level volatiles organic compounds, keeping future tenants safe from exposure. The environmental consultant required a turnkey installation for the barrier and venting system along with quality assurance/ quality control testing of the system. The consultant also evaluated a single-layer polyolefin sheet system that relies on taped seams and is not installed by a certified applicator or smoke tested. In comparing the approaches and costs of the two options, the MonoShield system was selected based on the time-efficient, certified installation in addition to its proven chemical resistance. The installation was completed across the 6,000 square feet foundation in less than two days at a low cost. The consultant, also a certified Land Science Inspector, provided an added layer of quality assurance and value to the developer by overseeing and documenting the installation process.

Featured Case Study: TerraShield Protects Future Occupants from Harmful Vapor Intrusion

TerraShield Protects Future Occupants from Harmful Vapor Intrusion

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. The developer utilized brownfield funding from the local authority to conduct the necessary environmental remediation measures.

Featured Project Snapshot: Leading Hotel Chain Moves Forward With Brownfield Site Construction Following Installation of Vapor Barrier System

Installation of Vapor Barrier System
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.

Land Science Sheds Light on How Office Worker Migration Trends Intensify Vapor Intrusion Concerns

SAN CLEMENTE, Calif.–(BUSINESS WIRE)–The “new normal” for office workers post-COVID-19 is expected to look very different from today’s landscape, with leading experts projecting a move away from traditional high-rise offices toward new construction of low-rise industrial parks that enable continued social distancing. Land Science, a division of REGENESIS, is actively addressing the increased vapor intrusion risk resulting from the rising trend in new office park construction on brownfields and other environmentally distressed properties—in an aim to mitigate the long-term health risks these contaminants pose to workers.

COVID-19 is Driving a Trend Away from Traditional Office Workspaces
The COVID-19 pandemic resulted in a dramatic shift in workplace geography as workers moved from centralized office locations to home-based offices. Stanford economist Nicholas Bloom, a leading researcher studying the work-from-home trend, notes: “[An] incredible 42 percent of the U.S. labor force is now working from home full time.” Bloom also suggests that new office building construction will be altered post-COVID-19 based on an increased desire for social distancing. He states, “instead of building more office skyscrapers – which has been the dominant theme over the past 40 years – I predict that COVID-19 will dramatically shift the trend to industrial parks with low-rise buildings.”

The predicted shift to new office spaces at former industrial parks matches established construction trends in the residential and mixed-use building sectors. Due to inexpensive land, tax credits and other incentives, redevelopment of these former brownfields into living and retail space has been robust during the past decade.

Increase in Risks to Exposure of Potential Toxic Chemical Vapors
This office worker migration trend will result in a significant increased risk for worker exposure to potentially toxic chemical vapors left behind from past industrial activity. Chemical vapors are formed when substances containing chlorinated solvents, petroleum hydrocarbons or other volatile compounds commonly used in industry are spilled or improperly disposed of. Over time, these chemicals migrate through soil, contaminating groundwater and forming chemical vapor plumes.

Building occupants might be at risk of exposure to indoor air containing these vapors if a building is constructed within a contaminant vapor plume footprint. Inhalation of chemical vapors is often hazardous to human health, even at indoor air concentrations not detected by smell.

Effective Contaminant Vapor Barriers Address Risk
Land Science’s vapor intrusion mitigation systems incorporate the latest technological advances to offer the highest chemical protection available. These advanced systems comprise patented, state-of-the-art materials, including metalized films and nitrile-modified asphalt sealants that offer up to one-hundred times more chemical protection than other vapor intrusion mitigation systems like plastic sheets with taped seams and spray-applied waterproofing “boots.”

While offering the highest level of protection against vapor intrusion, these systems are often easier and faster to install and are priced competitively. Brownfield property developers are rapidly increasing the incorporation of these systems into their building plans as a means to address any potential vapor intrusion risk, known or unknown, and to ensure development stays on schedule.

Preemptive Installation May Be Less Expensive Than Investigation and Monitoring
A vapor mitigation system’s cost is insignificant relative to a new building project, and Land Science’s certified applicators can install these advanced systems quickly without delaying construction.

Comparative cost analyses have shown that it is often less expensive to proactively install a contaminant vapor barrier rather than investigate and monitor whether it is needed. Once installed, these vapor mitigation systems provide a high level of assurance for personal safety. According to the U.S. EPA’s Brownfields Technology Primer: “Incorporating relatively inexpensive mitigation (prevention) techniques into the construction of new buildings, rather than retrofitting them later, will result in significant cost savings and help avoid the occurrence of vapor intrusion in the future.”

Vapors Effectively Mitigated in Houston Arts District

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.

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.
