Shotcrete in Below-Grade Foundation Walls: Implications for Waterproofing
As the demands for accelerated construction schedules and cost-effective foundation systems continue to rise, the motivation to use shotcrete for foundation walls has increased as a compelling alternative to more traditional cast-in-place concrete. While the application of shotcrete offers notable advantages in terms of construction schedule and cost, it also introduces distinct challenges related to the installation and performance of below-grade waterproofing systems.
This presentation will examine the practical implications of using shotcrete for foundation walls, with a focus on below-grade waterproofing systems and details. The presenters will review case studies from recent projects to illustrate lessons learned and to discuss strategies to mitigate the potential weaknesses of shotcrete foundation walls. Learners will gain a deeper understanding of when and how shotcrete can be effectively integrated into enclosure design, and where it may introduce risks that require strategic forethought and mitigation.
Learning Objectives
- Identify the advantages and limitations of shotcrete as an alternative to traditional cast-in-place concrete for below-grade foundation walls.
- Evaluate the impacts of shotcrete application on the performance and installation of below-grade waterproofing systems.
- Analyze real-world case studies to understand common challenges and lessons learned from projects using shotcrete foundation walls.
- Develop strategies for effectively integrating shotcrete into building enclosure design while mitigating potential performance risks.

José has more than a decade of experience in enclosure consulting. His project portfolio varies in type and budget, including multi million-dollar single buildings to multi-billion-dollar full block redevelopments. His experience includes projects in the USA, Canada, Mexico and China. José is passionate about building science, unitized facade systems, and sustainability. When not working on a project, he enjoys researching global trends in the design and construction industry, writing articles on trending topics, and presenting at conferences and industry events.
