Foundation Waterproofing Replacement in an Urban Environment: A Historic University Building Case Study

Foundation Waterproofing Replacement in an Urban Environment: A Historic University Building Case Study

Many commercial and institutional buildings outlast the effective life of their original foundation waterproofing and drainage systems. They suffer from water infiltration, which deteriorates building components and disrupts building operations. In these instances, owners face a choice to conduct repairs to manage water infiltration at the interior or prevent water infiltration from the outside of the building. Some owners require the reliability of exterior-applied replacement foundation waterproofing to meet building use or service life requirements. The design and construction of these remedial projects typically require extensive excavations and present several logistical, architectural, civil, geotechnical, and structural engineering challenges. In this webinar, we will present a summary of the Krieger Hall foundation waterproofing and colonnade repair project at Johns Hopkins University. The session will focus on the collaborative, multidisciplinary approach taken to design repairs to the building enclosure, structural, and subsurface drainage systems. The case study will also highlight the unique challenges associated with performing work on an urban university campus and integrating modern foundation waterproofing into the historic fabric of the nearly century-old structure.


After attending this webinar, participants will be able to:

  • Describe the conditions that may lead an owner to undertake a foundation waterproofing replacement project.
  • Illustrate the complicated nature of a project with an extensive excavation and disruptive construction site in an urban university campus environment.
  • Highlight the unique approaches used in designing foundation waterproofing replacement on a historic mass masonry building.
  • Identify examples of how the project team anticipated and addressed construction challenges to achieve a successful project outcome.

Participants will earn 1.0 AIA CES Learning Unit (LU/HSW) for attending the live webinar. Registration is free. Please note that space is limited – email events@sgh.com to join our waitlist if the session is closed when you register.

Joseph  Rogers
Joseph Rogers | Principal

Joseph Rogers collaborates with his clients to identify and focus on the critical elements required to maximize the service life of their structures. He specializes in building enclosure engineering, including design consulting for new construction, investigating performance problems, developing multidisciplinary rehabilitation programs, and designing and administering repairs for modern and historic structures. His work encompasses a wide range of building enclosure systems and materials, including roofing, modern and historic wall systems, below-grade waterproofing, and flooring. He leverages his broad building enclosure engineering experience to help clients with construction-related disputes by investigating building enclosure issues and serving as their expert witness. He also has a passion for giving back through education, and teaches the Investigation, Diagnosis, and Rehabilitation course for Johns Hopkins University’s Department of Civil Engineering.

Bryan Strohman | Associate Principal

Bryan Strohman has diverse experience in geotechnical, civil, and structural engineering, including investigating, designing, and rehabilitating a variety of structures. His work experience includes mechanically stabilized earth walls, slopes, foundations, piles, excavation support systems, retaining walls, artificial turf fields, drainage systems, buried arches, box culverts, pipes, three-sided structures, bridges, and nuclear facilities. He has performed a number of investigations of mechanically stabilized earth wall failures, foundations, and damage to underground structures. His technical expertise is focused on heavy civil structures, soil behavior, and drainage systems. His broad experience has also involved numerous soil-structure interaction analyses. He is an active participant in the American Society of Civil Engineers’ Embankments, Dams, and Slopes Committee, and currently serves as the committee secretary. He is also a member of the Deep Foundations Institute’s Codes and Standards Committee and the Boston Society of Civil Engineers Section Geo-Institute Technical Group.
