An Introduction to Geotextiles for Soil Wall Reinforcement

J. Paul Guyer, P.E., R.A., Fellow ASCE, Fellow AEI

This course provides an introduction to geotextile reinforced soil walls. Soil, especially granular, is relatively strong under compressive stresses. When reinforced, significant tensile stresses can be carried by the reinforcement, resulting in a composite structure which possesses wider margins of strength. This extra strength means that steeper slopes can be built. Geotextiles have been utilized in the construction of reinforced soil walls since the early 1970’s. Geotextile sheets are used to wrap compacted soil in layers producing a stable composite structure. Geotextile-reinforced soil walls somewhat resemble the popular sandbag walls which have been used for some decades. However, geotextile- reinforced walls can be constructed to significant height because of the geotextile’s higher strength and a simple mechanized construction procedure.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
