Watch Part 1

Join CHANCE® for a two-part webinar to learn how extreme events such as earthquakes, tsunamis, storm surges, hurricanes, floods and other natural disasters often cause substantial damage to the foundation of existing structures that requires rapid response for repair. In some areas, recurring events produce repeating damage to traditional foundations of lightly loaded residential and commercial structures. Learn why helical piles are an attractive engineered solution that can be used to provide rapid high capacity load bearing characteristics in most geologic settings for both new foundations and remedial repair.

Learn what to consider when engineering foundations that will likely encounter extreme weather events.
Explore real-world examples of successful implementations of helical piles to remediate a structure following a storm event.
Compare the pros and cons helical pile technology to alternative methods.
Discuss how to design helical pile foundations for seismic zones.
Discover the research and testing that has been done to prove the resilience of helical piles during seismic activity.
