Featured Case Study | 1.2 Million Square Foot MonoShield Application Protects Historic Steel Manufacturing Site 

On the site of one of the largest former steel mills in the world, a large logistics center redevelopment project is underway. The development promises to transform the historic site into 15 million square feet of warehousing space and bring the community anywhere from 5,000 to 10,000 new jobs. Working with the environmental consultant and the developer, Land Science was chosen to incorporate the MonoShield contaminant vapor barrier system to preemptively address any potential vapor intrusion issues.

Technical Data Sheet | One of the Fastest Vapor Barriers to Install is Also One of the Safest 

MonoShield is a single-layer, underslab contaminant vapor barrier offering superior chemical resistance, durability, and ease of installation versus traditional sheet membranes. MonoShield is an optimal mitigation solution to reduce liability for large, slab-on-grade buildings where installation speed is critical, for sites with a low-level vapor intrusion (VI) risk, or for use in conjunction with active sub-slab venting systems.

eBook | 5 Reasons to Consider a Preemptive Vapor Barrier System 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.

Case Study | Retro-Coat Protects Los Angeles Contemporary Art Gallery 

PCE was detected in the soil gas beneath a commercial building housing a contemporary art gallery and studio suite in a Los Angeles neighborhood. Investigations revealed that a regional groundwater contaminant plume, originating from an upgradient source, was the cause of PCE in the soil vapor, and indoor air sampling results showed that the intrusion of PCE-impacted soil vapor to the indoor air was a complete exposure pathway for on-site workers. As a result, a mitigation plan was required to protect against potential VI exposure to PCE. The contaminant vapor barrier selected for implementation was Retro-Coat, a low-permeability, epoxy coating system proven effective at preventing VI of volatile organic compounds like PCE and a favorable choice for existing structures.
