StegoHome Below-Slab Vapor Protection is a high-performance plastic sheet membrane designed for use beneath new concrete floor slabs to prevent the natural transmission of moisture vapor and soil-gas, like radon, into a home's foundation and interior living space. StegoHome is made using innovative multi-layer technology and only high-grade resins to provide unmatched vapor protection, durability, and longevity below basement floors and slabs-on-grade.

Unlike generic, often 6-mil thick poly sheeting, which can be easily damaged during installation and susceptible to deterioration, StegoHome exceeds industry performance standards and requirements for below-slab vapor protection and comes with a first-of-its-kind Life of the Building™ Warranty.

PROFESSIONAL REVIEW

"An ounce of prevention is worth its weight in gold.  I can guarantee when you’re dealing with the building envelope, there is not an excess of payment at the top end that doesn’t come back, threefold."
