Design Considerations for Basal Reinforced Embankments – Part 1


Basal Reinforced Embankments on Soft Foundations (Part #1)

Course Overview

Chris Lawson will be providing an insight into the design of embankments over soft ground with a focus on key considerations around reinforcement selection and performance to meet local Road Authority requirements. This informative presentation is split into two 1-hour sessions with different learning outcomes. Part #2 can be found in the Upcoming Courses section of Geofabrics Academy. 


Chris Lawson, Technical Director of TenCate Geosynthetics Group Asia, received his Engineering Degrees from The University of New South Wales. He has worked in the field of geosynthetics for 40 years in Australia, Europe, North America and Asia. During this period, Chris has served on international organizations developing Standards and Codes of Practices for geosynthetics and geosynthetics structures.

Chris has acted as technical advisor on many large scale geosynthetics projects in the field of embankments, reinforced soil techniques, coastal, hydraulic and environmental engineering structures in many countries. He is the author of over 50 technical papers on geosynthetics, geotechnical engineering, mining and hydraulic and coastal engineering.
