Are we detailing the placement of vapor barrier in the typical slab-on-ground design all wrong? When moisture develops on a concrete surface, where is it coming from? Below the surface or above? Bob Higgins, a concrete and waterproofing expert, joins the podcast to help us answer these questions. We discuss extensively the science of how water vapor is created and why today's concrete must be internally cured to perform its best. If you want to learn about another controversial topic in the concrete industry, you'll enjoy this podcast. Listen to see if we can blow a hole through the ACI 302 standard!
