Project Highlights

  • 186,000 square foot Geo-Seal Barrier installed to meet regulatory goals
  • Site development kept on-time and on-budget
  • 60-mil barrier system chosen to offer highest level of protection against methane exposure

Project Summary

During initial environmental due diligence, this property was noted to have elevated methane in the subsurface (in excess of 15% by volume). While this was a perfect location for a multi-unit residential development as it was next to major traffic corridors and near many Fortune 500 employers, the environmental concerns paused redevelopment planning.

Modern Geosciences (Modern) was asked to develop a remedial strategy that could incorporate a methane mitigation system within the building design. Drawing on over three decades of methane mitigation experience, Modern’s lead design engineer developed a cost-effective approach that satisfied all the parties plugged into the development. This included a customized passive collection layout and use of Geo-Seal to mitigate potential vapor concerns.
