TerraShield Protects Critical Aircraft Maintenance Facility at Naval Station Norfolk
Project highlights:
- Advanced vapor barrier provides long-term protection for Navy’s new corrosion control and paint hangar
- TerraShield was chosen for its proven chemical resistance, high durability, ease of installation, and ability to meet rigorous military construction standards.
The U.S. Navy planned the construction of a new Corrosion Control and Paint Facility (Building P-1035) at Naval Station Norfolk in Virginia. The facility, strategically located in the heart of the naval base, provides critical maintenance capabilities for MH-60R/MH-60S and V-22 aircraft. The single-story hangar includes three specialized bays—a plastic media blasting bay, a painting bay, and a wash rack bay—supported by mission-essential spaces. Due to potential vapor intrusion concerns associated with historic Navy maintenance activities and known contaminants in the area, the project team proactively selected Land Science’s TerraShield® Metallized Contaminant Vapor Barrier.
Advanced Vapor Barrier Protects From Potential Vapor Intrusion Risk
Project highlights:
- Nitra-Seal ensures safe indoor environment at Camp Lejeune
- Nitra-Seal chosen due to its excellent chemical resistance against VOCs and PHCs, proven track record in similar military applications, competitive cost, and streamlined installation process suitable for military construction timelines.
At Marine Corps Base Camp Lejeune, North Carolina, the 2nd Marine Division (MARDIV) planned the construction of a new Battalion Headquarters facility. Given the historical presence of environmental contamination at various locations across the base, proactive measures were required to mitigate potential vapor intrusion risks from volatile organic compounds (VOCs) and petroleum hydrocarbons (PHCs). Ensuring the health and safety of Marines and support personnel was paramount. The project team selected the Nitra-Seal® vapor mitigation system to effectively address these vapor intrusion concerns.

Nitra-Seal Installed to Prevent Vapor Intrusion for National Coffee Chain Expansion
Project highlights:
- Vapor mitigation for new coffee retail location to support national brand expansion
- Nitra-Seal® installed to prevent vapor intrusion from petroleum hydrocarbons
A national coffee chain selected a high-visibility site in Northern Illinois for a new quick-service retail location as part of its U.S. expansion. Due to potential vapor intrusion risks from petroleum hydrocarbons linked to former site use and nearby properties, the development team proactively installed Nitra-Seal®, a proven vapor barrier system known for its chemical resistance and cost-efficiency. A Land Science® Certified Applicator completed the installation under a compressed timeline and in accordance with manufacturer specifications, ensuring the project stayed on schedule. With Nitra-Seal in place beneath the foundation, the site is now effectively protected from vapor intrusion, supporting the client’s commitment to safety, operational excellence, and responsible redevelopment.

Nitra-Seal Protects First Responders at New State-of-the-Art Fire Station
Project highlights:
- Vapor mitigation project for new fire station with oversight from county Department of Environmental Health
- Nitra-Seal® installed to prevent vapor intrusion from volatile organic compounds, including benzene, bromodichloromethane, and chloroform
To meet growing emergency needs, a Northern California fire station was built on a former industrial site with contamination history. Listed on the Department of Toxic Substances (DTSC) Hazardous Waste site list due to a past UST leak, environmental tests found elevated concentrations of benzene, bromodichloromethane, and chloroform in soil gas, posing a vapor intrusion risk. To mitigate this, the city entered a Remedial Action Agreement with the county, which required a Vapor Intrusion Mitigation System (VIMS) to protect first responders. The environmental consultant designed a site-specific contaminant vapor barrier system using Nitra-Seal, which is applied beneath the foundation, creating a long-term barrier against vapor intrusion. The Nitra-Seal vapor barrier was installed by a Land Science certified installer and was completed in accordance with the required QA/QC procedures.

TerraShield Mitigates Methane Risk For Residential Development
Case study highlights:
- Redevelopment of a 1.9-acre site into 34 three-story residential units
- Historical contamination from oil production and automotive repair activities
The project site, a 1.9-acre property in Huntington Beach, California, is being redeveloped into 34 three story residential units. Historically, the site was associated with oil production, including four abandoned oil wells, oil storage tanks, and automotive repair operations. The site required methane mitigation due to the potential for gas generation from historical oil field operations and organic-rich soils. Methane testing revealed concentrations exceeding regulatory thresholds, posing a potential risk to future residents. The redevelopment team prioritized addressing these challenges to ensure safety and regulatory compliance by designing and installing a proven and highly chemical resistant contaminant vapor barrier solution.
