ASTM (American Society for Testing and Materials) E1745 is the Standard Specification for Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs. This standard requires products undergo conditioning testing designed to simulate in-service (under-slab and installation) conditions, and it classifies vapor retarders based on their tensile strength, puncture resistance, and water vapor permeance ratings.

For three generations, Chavez Concrete has been one of the most trusted names in New Mexico. As one of the state’s oldest and largest concrete companies, Chavez knows what it takes to get the job done correctly: dedication, craftsmanship, hands-on leadership, and the ability to select the right tools for the job. When Chavez poured concrete at a Cost Plus World Market® and Bed Bath and Beyond® in Santa Fe, they followed the same steady course and selected Stego® Wrap Vapor Barrier for the project’s below-slab moisture protection.
