Nitra-Seal Ensures Long Term Vapor Intrusion Protection for Quick Service Restaurant

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.

Background

Nitra-Seal is an advanced composite vapor barrier system incorporating a Nitra-Core™, a nitrile-advanced asphalt latex component applied between two layers of high density polyethylene (HDPE) material bonded to a geotextile. This multi-layer system provides enhanced protection against indoor air exposure to sub-slab chemical vapors. Nitra-Seal provides a significant improvement over comparable composite vapor barrier systems on the market. In lab testing, Nitra-Core delivered 10x greater chemical resistance against VOCs in comparison to SBR latex asphaltic sprays. Nitrile’s chemical resistance is long-established, verified in the laboratory to be highly effective against a wide range of VOCs like chlorinated solvents, petroleum contaminants, and methane. Workers commonly use nitrile-enhanced materials in the environmental and medical fields as personal protective equipment (i.e., PPE) due to its chemical resistivity, puncture resistance, and tensile strength. These latter two features are uniquely beneficial for use in the construction industry where strong, flexible, and puncture-resistant materials are desirable for damage protection against moving construction workers, equipment, and tools.

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.

Client Spotlight: Torin R. Snyder, Principal at Rincon Consultants

Torin Snyder, Rincon ConsultantsWhen Torin Snyder isn’t swimming or being dance-dad extraordinaire, he can be found pursuing another lifelong passion – finding effective, creative solutions to complex environmental issues. Snyder is a principal at Rincon Consultants, Inc., a leading California-based environmental consulting firm and valued Land Science client. His career path was no surprise to him, as Snyder recalls his interest in the environmental sciences blossoming during his university days. When he began to explore the field as a potential career path, he soon realized environmental site assessment and remediation would provide the ideal avenue to satisfy his curiosity.

“I have always been fascinated in environmental sciences, but I found early on, and still find, that environmental remediation is especially interesting because it is always evolving with emerging chemicals, new clean-up goals, and new technologies,” Snyder says of the field. “This industry offers an opportunity to introduce innovative options to clients, enabling them to achieve their overall project goals and expectations, and it lets me learn and think outside the box.” Snyder joined Rincon in 2010 as a senior hydrogeologist and was promoted to principal in 2018. Prior to joining Rincon, he served as a project manager in the hydrogeology department for an environmental planning company.

To prepare for his career in environmental remediation, in 1999 Snyder earned his BS in Soil Science, with a Hydrology concentration, from California Polytechnic State University, in San Luis Obispo. “After-graduation, I focused on getting the certifications and licenses relevant to the environmental consulting industry. First, I became a Certified Professional Soil Scientist, then a Registered Environmental Assessor, then a Deputy Methane Building Inspector for the City of Los Angeles Department of Building and Safety. Later, I became a Professional Geologist, Qualified SWPPP Developer/Practitioner, Certified Hydrogeologist, and finally a Trainer of Record for the Qualified SWPPP Developer/Practitioner program. Sometimes people tease me for having so many initials behind my name.”

As a Principal for Rincon’s statewide Environmental Site Assessment and Remediation practice, Snyder is responsible for business development, client management, technical and quality control, and staff mentoring and development. He says of his many roles at the firm, “I provide leadership for the Environmental Site Assessment and Remediation group, and I support the Environmental Sciences and Land Use Planning group and Natural and Cultural Resource team at Rincon. The diverse clients and projects keep me engaged, while giving me new challenges to meet, which I enjoy very much.”

To stay abreast of new technologies and emerging trends, Snyder keeps up with seminars, conferences, and training programs for the field. “Our industry is always evolving,” he says. “So, education and training are critical to remain current with new solutions our clients expect and deserve. It seems there’s always a new or better way to complete a project.” With his diverse background, responsibilities and commitment to staying current in the industry, Snyder does his part to help Rincon achieve its long-term goal of “offering clients the best services, best products, and best people in our field.”

When it comes to working with Land Science, Snyder appreciates the company’s wide range of technologies. “Land Science has done a good job providing alternative products to solve vapor intrusion challenges. There are many solutions available, but few are as effective as those Land Science offers.” He goes on to say that “finding a product that is cost-competitive and that protects the occupants of the building is the most important consideration. Land Science offers multiple products for different applications, which is critical. For example, our clients like the protection that MonoShield™ offers for low-risk vapor intrusion sites and they appreciate that the product is cost-effective compared to most other vapor barriers.” Recently, Snyder has recommended MonoShield™ for a number of projects Rincon has tackled that included low-risk vapor intrusion concerns for low-income housing projects.

Residing in Carlsbad, California with his wife and two daughters, Snyder works out of the Rincon office there. In his free time, he enjoys the outdoors, with mountain biking, open-water swimming, and off-road triathlons (Xterra) topping his list of favorite activities. He likes them so much he participates in mountain bike and open water swim racing. “I’m a fairly competitive guy so I love to sign up for races,” he shares. “One of my favorite race experiences was when I competed in the Xterra Off-Road World Championship in Maui in 2018.” He also finds time to volunteer as an Advisory Council Member for the Natural Resource and Environmental Sciences Department at California Polytechnic State University, San Luis Obispo.

When asked what he enjoys most about his job, he points to the collaborative nature of working with co-workers and clients. “I also take satisfaction in providing a client an out-of-the- box solution for their specific problem.” And the most demanding aspect of his job? “Right now, the COVID-19 pandemic. This has changed our day to day routine and requires us to be nimble and adaptive to the new norm.” He also feels the trend of emerging chemicals, evolving clean-up goals, and discovering new solutions to help solve remedial challenges is here to stay- at least for some time. He continues, “As regulations become tighter, consultants will be forced to reconsider how a project is scoped and completed. For example, as clean up goals become more conservative, it may not be economically feasible to remediate a site the same way we did 10 years ago. Therefore, interim mitigation measures, like vapor barriers, sealing concrete floors, and HVAC modifications, need to be considered to reduce the time a building may sit unoccupied during remedial activities when there are indoor air concerns.”

And how would he encourage others to join his field of study? He concludes, “I would not necessarily use the word “encourage.” Finding your passion is the most important aspect to a rewarding, challenging, and successful career. So, I feel it’s critical for people who might be interested in this field to first understand their own passion- what makes them tick. Once this is understood, the path to a fulfilling and successful career path can be tailored to an individual.”

Land Science is proud to have Torin Snyder, Principal at Rincon Consultants, Inc., as a valued client and partner in environmental remediation, and appreciates his highly diverse background and approach in providing successful remediation outcomes for Land Science and its clients.

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.

Summary

An established, construction services company was developing a new corporate campus on a former industrial manufacturing site where chemical degreasing agents were used. Prior to the building’s planned construction, an investigation was conducted, identifying chlorinated volatile organic compounds (VOCs) in the subsurface. Based on the investigation results, the project stakeholders specified the installation of a vapor mitigation system to address the potential VOC vapor intrusion risk to future building occupants. The consultant and their client were familiar with Land Science’s full suite of vapor barrier systems and had installed their vapor mitigation technologies at other building sites in the past. The team specified Nitra-Seal® for this project based on its top-performing chemical resistance and installation efficiencies compared to other spray-applied barrier systems considered. The building’s unique foundation layout required a nuanced approach and site-specific design support from the Land Science team. The Land Science Certified Applicator installed the Nitra-Seal vapor mitigation system efficiently and according to specifications, allowing the new office campus construction to proceed without delay.

Summary

An expanding quick-service restaurant (QSR) chain planned a new store in the rapidly growing central Texas market at a former gasoline station site. Although there was no active environmental incident associated with past use, it is common for petroleum hydrocarbons (PHCs) to remain in the subsurface, undiscovered at former gas station sites. Using their knowledge and experience in developing similar properties, the QSR client recognized the potential risk of petroleum hydrocarbon (PHC) vapor intrusion. To ensure their future associates’ and guests’ well-being, the Nitra-Seal® vapor mitigation system was installed as a preemptive measure to protect against PHC vapor intrusion. Nitra-Seal was chosen because it provided the best combination of chemical resistance, installation efficiency and price compared to other similarly priced vapor barrier systems. The Land Science certified applicator completed the installation according to manufacturer recommendations within aggressive time and budget constraints, allowing the restaurant to proceed toward its scheduled opening in the Fall of 2020.
