Not all plastics are created equal — and not all vapor barriers perform the same under the slab. Recent ASTM testing and field analysis reveal how quickly generic, recycled poly can degrade beneath slabs, with visible disintegration and loss of moisture protection performance in as little as two weeks.

So what does that mean for builders, contractors, and homeowners who opt for a “just good enough” vapor barrier?

Join Matt Risinger and the Stego team for an in-depth look at below-slab vapor protection. We’ll break down the science behind material degradation, compare generic poly to high-performance vapor barriers, and explore the real-world consequences — from costly callbacks to poor indoor air quality.

Learn how smarter material choices under the slab can help you avoid costly callbacks, support better indoor air quality, and reduce long-term energy usage.

Key Takeaways:

1. What the Testing Shows
See how recent ASTM testing and field analysis exposed the rapid breakdown of generic 6-mil poly sheeting — including failures in moisture protection, radon protection, and resistance to degradation.

2. The Risk Beneath the Slab
Understand the real-world consequences of vapor barrier failure, including callbacks and flooring failures, and how these issues can impact both builder reputation and homeowner health.

3. Build Smarter, Not Harder
Learn how high-performance vapor barriers and integrated accessories streamline installation, reduce labor challenges, and deliver long-term protection backed by Stego’s Life of the Building™ Warranty.
