In this episode of the Build Show, Travis takes us through the process of properly waterproofing a below-grade foundation using insulated concrete forms (ICFs). Working on an addition to an existing home, Travis demonstrates how to create a crawlspace that stays dry while ensuring long-term durability. Sponsored by Polyguard, this episode highlights a full systems approach to moisture and pest control—covering everything from footing-to-wall detailing, sealants, and flashing tapes to drain boards and termite barriers. Travis explains why product compatibility is critical when working with ICFs, how Polyguard’s water-based adhesives eliminate concerns about foam damage, and how their TotalFlow drainage and TERM barriers provide comprehensive protection. Along the way, he shares practical installation techniques, tips for managing irregular surfaces, and best practices for ensuring continuity from footing to roof deck. Whether you’re a builder, remodeler, or DIYer, this episode gives you the knowledge and confidence to deliver a foundation that’s protected from water infiltration and termite intrusion for the long haul. Huge thanks to our episode sponsor, Polyguard.
