Geo-Seal vapor intrusion solution at airport
A vapor intrusion barrier was sought to protect the new structure from potential vapor intrusion and keep the project on schedule.

 

Project Highlights

  • Triple-layer protection and high puncture resistance addressed concerns over permeation into the building
  • Enhanced chemical resistance over spray-applied asphalt/latex material
  • Installation of Geo-Seal® allowed project to remain on schedule
  • Vapor-Vent trenchless system installed to collect and vent vapors from beneath the structure

 

 

Project SummaryDallas Love Airport Vapor Intrusion

The Dallas Love Field airport originally opened in 1917 and has over 90 years of aviation use. A major airline decided to expand their current facilities at Love Field which included the construction of a new maintenance facility. An underground storage tank was discovered prior to construction and insufficient historical site records caused concern for potential indoor air vapor in the new building. A vapor intrusion barrier was sought to protect the new structure from potential vapor intrusion and keep the project on schedule.

TITAN Engineering along with their client selected Geo-Seal Vapor Intrusion Barrier based on its enhanced chemical resistance and industry leading 20 year system warranty. The Geo-Seal triple layer protection allows for resistance of contaminant permeation breakthrough for a period 18X longer than that of simple asphalt/latex membranes.

Under a system warranty, Land Science warrants the integrity of the material and the workmanship of the certified Geo-Seal installer against chemical migration into the building.

Technology Description

Geo-Seal is a gas vapor management technology designed to eliminate vapor intrusion on Brownfields or any type of environmentally-impaired site. Geo-Seal is a chemically-resistant material placed between the foundation of the building and the soil pad to eliminate vapor intrusion pathways and stop contaminant vapors from permeating through the slab.

By deploying Geo-Seal, developers can ensure a healthy indoor environment while reducing the cost of site remediation and expediting site construction.
