Aggregate pier ground improvement systems have been used for over 25 years to provide shear reinforcement for unstable slopes and failed slopes for a wide range of projects, both public and private. Recent innovations in design and delivery methods have resulted in great value to owners and contractors by providing long-term, engineered solutions that save time and money compared to traditional earthwork solutions for shallow slide failures. This presentation will provide a brief description of short pile-and-plate slope repair methods and will use case histories where shallow slides have impacted existing pipelines and infrastructure to illustrate applications where this innovative and minimally invasive ground improvement solution has been utilized to repair failed slopes.
