TerraShield

TerraShield® is a multi-layer, composite, spray-applied vapor barrier with metalized film and a nitrile-advanced asphaltic core that delivers up to 100× greater vapor intrusion protection and 10× higher chemical resistance than conventional systems.

Robust. Chemically
Resistant. Proven.

TerraShield® is a multi-layer, spray-applied vapor barrier system that combines innovative metalized film technology with a nitrile-enhanced core, delivering orders-of-magnitude greater vapor intrusion protection, up to 100× more effective in laboratory testing, while providing up to 10× higher chemical resistance than traditional styrene-butadiene rubber (SBR) modified spray-applied systems.

What is it?

TerraShield® is a multi‑layer, spray‑applied vapor barrier system engineered to deliver exceptional vapor intrusion protection. It incorporates metalized film technology and a nitrile‑advanced core, providing as much as 10× higher chemical resistance than traditional SBR‑modified spray‑applied systems. TerraShield consists of multiple layers including TerraBase+, a nitrile-advanced Core, and a robust and durable protection fabric. Together, TerraShield offers superior durability and performance in demanding construction environments. The result is a proven, chemically resistant barrier designed for maximum constructability and dependability.

Is it right for my project?

TerraShield® is ideal for projects that demand the highest level of vapor intrusion protection and chemical resistance. Its multi‑layer design and proven laboratory performance make it especially well‑suited for sites with elevated contamination risks or where long‑term durability is critical. TerraShield has been tested to perform against a wide range of contaminants including cVOCs, petroleum compounds, methane, and radon. If your project requires a robust, constructible barrier that outperforms traditional spray‑applied systems, TerraShield® is an excellent fit.
