Construction Time Reduced with New Vapor Barrier System
This case study reviews a brownfield site that posed multiple remediation challenges with a variety of known contaminants including arsenic, lead, and methane. To build on the site would require a unique foundation along with a vapor intrusion mitigation solution. Working with the developer Ashley Capital’s environmental consulting firm SME, Land Science recommended MonoShield, a new and innovative vapor intrusion mitigation system. This modified asphalt-nitrile vapor barrier system is designed to withstand even the toughest vapor intrusion conditions, ensuring a safe environment for years to come. SME chose to be the first to install MonoShield because it provided the best chemical resistance for this brownfield site and would also save the client time and money.
This case study features the following:
- Liberty Park is being transformed from underutilized into a property that will bring jobs and growth to the community.
- MonoShield has the efficiency of a prefabricated barrier system and the flexibility and responsiveness of a spray-applied component for sealing penetrations, wall terminations, and seams.
- MonoShield is both time — and cost-efficient; it can be installed 30-40% faster than alternate plastic sheeting or HDPE systems.
- Cooperation among numerous stakeholders: The Michigan Department of Environment, Great Lakes, and Energy (EGLE), Ashley Capital, SME, Oliver Construction, Land Science, and S&H Waterproofing.
