MSE walls have been successfully used for many years throughout the highway infrastructure market. Many ground improvement solutions are available to remedy poor soil conditions when it is necessary to build an MSE wall over low-bearing capacity and settlement prone soils. Using ESCS for load reduction in these situations is frequently a viable and cost-efficient solution. This webinar will discuss the design considerations for MSE walls using ESCS as a lightweight fill and evaluate its properties for compatibility. MSE walls with lightweight fill have been successfully built on many projects across the USA and the webinar will include relevant case studies.
