Foundation problems and Geotechnical Engineering (with Michael Simpson)

Structure Talk

In this episode of the Structure Talk podcast, Reuben Saltzman and Tessa Murry welcome Michael Simpson, a geotechnical engineer, who shares insights into forensic engineering, the impact of water management on foundations, and the differences between serviceability and safety in structural integrity. The conversation emphasizes the need for proper assessment and management of foundation problems, particularly in residential settings. Michael discusses the complexities of foundation settlement and movement, highlighting the importance of understanding soil types and their impact on construction. He explains the phases of movement after construction, the significance of monitoring foundation issues over time, and the various tools and techniques used for assessment. They also cover common repair solutions, the need for tailored approaches in foundation repair, and the potential impact of neighboring construction on a home's foundation.

Takeaways
Tessa shares her hybrid living situation between Florida and Minnesota.
Reuben discusses the challenges of recording podcasts while traveling.
Michael explains the role of geotechnical engineers in assessing foundation issues.
Forensic engineering focuses on existing structures with damage to determine causes.
Water management is crucial in preventing foundation problems.
Trees can affect soil moisture and contribute to foundation issues.
Settlement is a normal process in homes, but monitoring is essential.
Homeowners should document cracks to assess movement over time.
Serviceability issues often arise from cosmetic cracks rather than structural failures.
Proper assessment can prevent unnecessary repairs and costs. Soil type significantly affects foundation settlement.
Settlement can occur immediately or over several years.
Monitoring foundation movement is crucial for accurate assessment.
Multiple readings over time provide better insights into movement.
Common repairs include piers, compaction grouting, and stem wall repairs.
Tailored solutions are necessary for effective foundation repair.
Neighboring construction can impact foundation stability.
Understanding soil maps can aid in assessing risks.
Regular maintenance can prevent costly repairs.
Communication with homeowners is key to managing concerns.
