Stego – Is Your Below Slab Vapor Barrier Really Doing Its Job

From The Build Show.

Please join us for another Build Show Webinar! Today, Matt Risinger, Founder of Risinger Build and The Build Show, welcomes Stego Industries to the studio—featuring Tom Marks, Residential Project Manager, and Bret Houck, VP of Marketing & Development. Together, they tackle the critical question: Is your below-slab vapor barrier really doing its job?

The conversation dives deep into how vapor barriers protect homes from soil moisture, radon gas, and other contaminants that can impact air quality, flooring performance, and long-term building health. Through practical demonstrations, Matt and the Stego team reveal how easily concrete absorbs water vapor and why standard six-mil poly often fails to provide lasting protection.

They introduce Stego’s high-performance solutions—StegoHome, StegoCrawl, Pango, and Drago—engineered to deliver superior strength, durability, and compliance with ASTM E1745 standards. The discussion also covers key installation details, code updates, and best practices to ensure a continuous, effective barrier.

The takeaway: a small investment in the right vapor barrier pays off for decades by preventing moisture problems, flooring failures, and potential liability—ensuring healthier, more durable homes.
