Hotel Chain Moves Forward With Brownfield Site Construction

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. TerraShield® was specified to provide the highest level of chemical resistance and long-term barrier performance available on the market.

Superior Chemical Resistance Over Any Vapor Barrier on the Market Today

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. Backed by a robust warranty and installed by Land Science-certified applicators, each TerraShield installation is rigorously tested to ensure the quality of every seal and ultimately the complete vapor barrier system installed.

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).

In this live European webinar, Blayne and Tom discuss the challenges of vapor intrusion assessments and the benefits of continuous monitoring. They are joined by Rick Gillespie, Senior Vice President of Land Science, the vapor mitigation division of REGENESIS.

With vapor intrusion assessments, typically only a few contaminant concentration measurements are made, so it is often difficult to reach a conclusion if the vapor intrusion pathway is a concern. The result is that vapor intrusion investigations can drag on for months to years before a conclusion can be reached regarding the potential risk. Such time periods are unacceptable if there is a potential risk to human health.

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.

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.
