Mario Sternad, Senior Engineer with Stantec Consulting Services, Inc., draws immense satisfaction from providing effective solutions to address contaminants in our ever-changing environment. His responsibilities include in-situ cleanup technologies for soil vapor, soil, and groundwater, as well as vapor intrusion and vapor barrier design. He shares, “I prepare RIFS, RAPs and WPs for soil and groundwater remediation of VOCs, chlorinated solvents, hydrocarbons, petroleum, metals, and pesticides.” In addition, Sternad acts as a Stantec design lead and advisor during field work and construction, system and process development, and equipment design.

Sawyer Yards is an apartment community located in Houston’s vibrant Arts District neighborhood. Chlorinated solvents were detected in soil gas, posing a potential vapor intrusion risk to future residents. The original vapor mitigation system (VMS) specification called for a single layer barrier with taped seams. However, the building’s foundation contained many utility penetrations and terminations, requiring numerous taped seams. These taped seams significantly reduce application efficiency and ultimately result in potential barrier weak points. In contrast, MonoShield® incorporates a spray-applied nitrile-advanced asphalt latex, offering superior application efficiency with unmatched chemical resistance.

MonoShield is a chemically resistant and easy-to-apply barrier specifically designed as a preemptive solution for vapor intrusion at brownfield redevelopment sites. It is backed by unparalleled design support, standard industry warranty, and a network of certified applicators who can ensure quality installation. To learn why developers are increasingly turning to MonoShield for a fast and cost-effective preemptive vapor mitigation solution, download the brochure.

5 Reasons to Consider a Preemptive Vapor Barrier to Protect Your Property Investment

Historically, easily-punctured thin-mil plastic sheets or inflexible and difficult-to-seal High Density Polyethylene (HDPE) Barriers were the only option for vapor mitigation at large warehouses or sites where regulatory requirements were not a driving risk factor. These solutions offered either chemical resistance or constructability, but not both. Composed of an innovative, metalized-film, MonoShield sets the standard for preventing diffusion and permeation of chemical vapors. Its nitrile-based asphalt latex ensures a seal far more effective and easier to apply than tape-based or heat-welded systems. Download the ebook to learn more.

A growing manufacturer looking to expand its operations purchased a vacant industrial facility in Lansing, Michigan, where chlorinated solvents were used and spilled into the subsurface. The environmental consultant was asked to address the suspected vapor intrusion concerns resulting from the former industrial operations. In working with the Michigan Department of Environment, Great Lakes & Energy (EGLE), the consultant proposed utilizing the Retro-Coat® Vapor Intrusion Coating System, in combination with passive venting, to ensure safe indoor air for the future workers.

Vapor intrusion occurs when there is migration of vapor-forming chemicals from any subsurface contaminant source into an overlying building. When vapor intrusion is detected, it becomes necessary to design a solution to mitigate the problem. Retro-Coat™, a chemically resistant coating designed to resist aggressive chemical vapors, is a cost-effective technology with many advantages over alternative options for existing structures and has been gaining popularity and acceptance as an effective vapor intrusion mitigation strategy.
