This course will discuss the use of shotcrete for structural applications, specifically in below-grade foundation walls. While the use of shotcrete is proven to accelerate construction schedules up to 25%, experience has shown that there are risks associated with this method of concrete placement versus traditional cast-in-place walls. During this session, we will cover the benefits and risks associated with shotcrete, how pre-applied waterproofing membrane systems should be designed for critical applications and the challenges that traditional waterproofing membranes face when used with shotcrete construction.

Learning Objectives

  • Compare and contrast shotcrete with traditional cast-in-place concrete walls for below-grade structural applications.
  • Describe how shotcrete installations can provide pathways for water migration and why traditional pre-applied waterproofing membranes fail to address these challenges.
  • Understand the benefits of hydrophilic grout-based shotcrete waterproofing systems and how they deliver differentiated performance in critical waterproofing applications.
  • Examine a case study where a properly designed waterproofing system was successfully used with shotcrete construction.
