EverShield™ is a multi-layer composite vapor barrier system engineered to deliver high-performance protection against vapor intrusion at moderate to high-risk sites or those sites requiring pre-emptive mitigation. In the evolving vapor barrier market, cost-efficiency and performance must go hand-in-hand. EverShield offers the solution for any type of project.
Robust. Chemically
Resistant. Proven.
EverShield is a composite vapor barrier system designed for installation beneath concrete slabs. It combines the proven protection of an EVOH base layer with the flexibility and durability of a spray-applied nitrile-advanced core layer.
Featuring a seamless three-layer configuration that includes Shield10™, Nitra-Core®, and Land Science Protection Fabric™, EverShield™ provides enhanced chemical resistance, durability, and long-term protection beyond traditional polyethylene-based barriers.
What is it?
EverShield is a composite vapor barrier system developed to control vapor intrusion beneath slab-on-grade construction. The system integrates three protective layers to create a seamless, redundant barrier designed to outperform traditional polyethylene membranes.
With its EVOH-enhanced base layer and nitrile-advanced core, EverShield delivers superior resistance to chlorinated solvents, petroleum compounds, methane, radon, and other volatile organic compounds while maintaining exceptional puncture and tear resistance.
Is it right for my project?
EverShield is ideal for commercial, retail, multi-family, and industrial developments where vapor intrusion risk is a concern. It is particularly well-suited for sites with numerous utility penetrations, complex foundation designs, or projects requiring enhanced chemical resistance and long-term durability.
If your project demands a robust, redundant barrier system that can be integrated with active or passive sub-slab venting for some of the highest levels of vapor intrusion protection available, EverShield is a strong fit.

"EverShield is better than rigid barriers, because instead of using tapes and boots that peel apart, the spray allows the barrier to seal."
