EP #075: How to Unlearn Everything You Know About Moisture in Concrete


Listen Later

Summary

In this episode, Seth interviews Robert Higgins, a flooring concrete consultant specialist, about the issue of moisture in old concrete. Robert explains that moisture in older concrete is caused by a condition called ionic dew point, where particles migrate to the surface due to diffusion, not moisture migration.

He emphasizes the importance of addressing older concrete differently and recommends grinding off the surface to remove accumulated salts. Robert also discusses the acclimation of adhesive and flooring products to prevent moisture accumulation. He highlights the need for proper testing and understanding of environmental conditions to avoid moisture issues.

Takeaways

  • Moisture in older concrete is caused by ionic dew point, where particles migrate to the surface due to diffusion, not moisture migration.

  • Adhesive and flooring products should be acclimated to the same temperature as the concrete to avoid moisture accumulation.
  • Proper testing and understanding of environmental conditions are crucial to prevent moisture issues in flooring installations.
