Below-grade areas often provide critical space for building owners and occupants, but their use also brings added risk of water intrusion. Poorly performing systems can lead to costly repairs due to the lack of access after construction. Designing below-grade waterproofing systems is a complex exercise that entails more than just selecting a waterproof membrane. In this webinar, we will discuss why we waterproof below-grade spaces, explore the importance of system selection, and share key principles of below-grade waterproofing approaches. 

After attending this presentation, participants will be able to:

  • Understand what site conditions may affect the selection of below-grade waterproofing. 
  • Outline the decision-making process in designing a below-grade waterproofing system.
  • Understand how waterproof membranes perform and the processes for selecting and installing them.
  • Discuss the challenges of remediating failed or poorly performing below-grade waterproofing systems.
