In this episode, Suzan Chin-Taylor sits down with Charlie Lerman a.k.a. The Grout Geek, to demystify the real differences between hydrophilic and hydrophobic polyurethane grouts. It’s more than just water-loving vs. water-repelling—this episode dives into flexibility vs. rigidity, reaction times, environmental conditions, and why real-world field performance often differs from lab tests.Whether you're dealing with crack sealing, I&I control, or freeze-thaw environments, this episode will help you choose the right product for the job—and avoid costly rework.🔍 What You’ll Learn:- Why flexibility matters more than water affinity- How reaction timing and viscosity affect performance- When to choose hydrophilic or hydrophobic grouts based on site conditions- The financial costs of recurring leaks and bad grout choices- Why manufacturer consultation is key—even for pros🎯 Pro Tips from Charlie "The Grout Geek" Lerman:- Hydrophilics need moisture, not saturation.- Hydrophobics work well in dry and freeze-prone environments.- Use flexible grouts for cracks and movement-prone joints.- Don’t just go by datasheets—ask the manufacturer!🧠 If you're a contractor, engineer, or municipal pro, this episode is a must-listen for smarter infrastructure repair decisions.👉 Connect with Charlie Lerman🔗 LinkedIn: https://www.linkedin.com/in/charlielerman🌐 ncfigeo.com📧 thegroutgeek@gmail.com🎧 Subscribe to the Smells Like Money Podcast:Don’t forget to subscribe to the Smells Like Money Podcast for more insights and innovations in the wastewater industry.
