Former St. Louis Chemical Plant Incorporates Geo-Seal and Vapor-Vent for Redevelopment Project

Project Highlights

  • Geo-Seal applied to over 70,000 square feet of commercial space
  • Redevelopment project is projected to create more than 1,000 new jobs in the St. Louis area

Project Summary

A former Solutia chemical plant, located in St. Louis, Missouri, in between the Mississippi River and St. Louis, required environmental remediation for safe redevelopment. The developers plan to turn the brownfield site into industrial and warehouse space. The redevelopment project is projected to significantly impact the area by providing more than 1,000 jobs.

The environmental remediation process included removing contaminated soil and treating contaminated water, as well as protecting buildings from possible vapor intrusion. In order to prevent vapor intrusion, the contractors installed over 70,000 square feet of Geo-Seal with a vapor ventilation system. Geo-Seal and Vapor-Vent were installed in between the soil pad and the foundation of the new buildings. Installing Geo-Seal, a composite and chemically resistant membrane system, effectively seals all entry pathways into the building preventing harmful vapor intrusion. In conjunction with Geo-Seal, Vapor-Vent, a ventilation system, allows for the natural buildup of underground vapors to be safely diverted and diffused above ground. The vapor barrier system ensures safety from vapor intrusion for this brownfield redevelopment.
