Overview
Reinforced soils are structures with the inclusion of multiple horizontal layers of planar soil reinforcement. The inclusion of soil reinforcement enhances the shear strength and stiffness of the reinforced soil structure. Soil particles are restrained from movement either due to confinement within the reinforcement apertures or simply by surface friction at the top and bottom of the reinforcement.
Soil structures with steepened face angles of up to vertical are possible with soil reinforcement which otherwise would require a large soil fill volume and a natural fill slope. The reliability of modern soil reinforcement products means that engineers are now confident in designing these structures.
Improvement in the polymer technology and manufacturing process also ensures that the soil reinforcement products are consistent in quality and performance. International codes of practice including AS4678 are now well established on the design of these structures.
In recent years, there have been vast development in the multiple form of facing systems of the reinforced soil. These facing systems form an essential component of the reinforced soil structures. Beside ensuring durability, the facing systems also determine the final look, affecting installation productivity and finally types of fills.
This presentation looks at some of the reinforced soil structures facing systems available in Australia and discuss the above aspects. The choice of facing systems allows engineer to design them with options considering the many factors in a typical construction project.
Key messages-
- Introduction and design of reinforced soil structures
- Common facing systems in Australia
- Project case studies

Speakers
Allan Garrard is a Senior Principal of CMW Geosciences, a specialist geotechnical consultancy, and has over 35 years’ experience in Civil and Geotechnical/Geological Engineering spanning the planning, design, management and site supervision of many diverse projects. Allan has provided technical verification of many large projects both nationally and internationally and is called upon to provide expert witness services.
Eric Ewe is a specialist engineer with more than 26 years of experience. His experience includes designing reinforced soil slopes and walls, slope rehabilitation works, slope stability analysis and rockfall protection structures. One of his assignments consisted of being part of the panel for the “MBIE Rockfall Protection Structures Design Considerations Guideline”. Since 2020, he transitioned roles as Geofabrics Australia’s Slope and Walls sector’s Technical BDM.
Jim Kounetas is a civil engineer with over 37 years of experience in the Victorian building and civil construction industries, specialising in contract and project management. Throughout his career, he has held several key roles at companies such as Boral, Maccaferri, and Groundtech. Currently, he serves as the Sector Manager for slopes & walls at Geofabrics where he oversees commercial Sales & Sub-contracting, which encompasses the design, supply, and installation of civil projects in particular Retaining Wall Systems. Key projects that Jim has contributed to includes the Warrigal Road slip repairs for VicRoads, the Spillway for the Victorian Desolation Plant, and the retaining walls for Regional Rail Upgrades.
