Retaining/RSS walls
Retaining SolutionsRSS walls for bridges, roads and rail
RSS walls (Reinforced Soil Structure) use precast concrete face panels connected to steel strip or geogrid reinforcement in engineered compacted fill. Fencepac designs and constructs them for bridge abutments, road embankments, rail corridors, and heavy surcharge applications.
Reinforced soil when a conventional gravity wall is not viable
RSS walls (Reinforced Soil Structure) use precast concrete face panels connected to steel strip or geogrid reinforcement layers embedded in engineered compacted fill. The reinforced soil mass acts as a gravity structure.
RSS walls are used for bridge abutments, road embankments, rail corridors, and heavy surcharge applications where traditional retaining solutions are not viable. Fencepac designs them to TMR and AS4678 standards.
They sit in the same Fencepac retaining offering as crib, segmental, gabion, and MagnumStone — selected when the geometry, surcharge, or infrastructure interface needs a reinforced-soil mass with a precast face.

When RSS walls are specified
RSS systems we install
Precast facing and soil reinforcement specified to TMR and AS4678.
Precast Concrete Panel Facing
Precast concrete face panels for a clean, regular finish on infrastructure walls.
Steel Strip Reinforcement
Steel strip soil reinforcement embedded in engineered compacted fill.
Geogrid Reinforcement
Geogrid layers where the design calls for geogrid rather than, or as well as, steel strip.
Bridge Abutments
RSS specified for bridge abutments and heavy surcharge loads.
Road, Rail & Embankments
Used on road embankments, rail corridors, and major infrastructure where a conventional wall is not viable.
TMR and AS4678 Design
Designed to TMR and AS4678 standards, then built by Fencepac crews with engineered fill and hold-point certification.
Frequently asked questions — RSS walls
An RSS wall (Reinforced Soil Structure) uses precast concrete face panels connected to steel strip or geogrid reinforcement in engineered compacted fill. The reinforced soil mass acts as a gravity structure. Fencepac designs and constructs RSS walls for infrastructure and heavy surcharge applications.
RSS walls are used for bridge abutments, road embankments, rail corridors, and heavy surcharge applications where traditional retaining solutions are not viable.
Yes. Fencepac designs RSS walls to TMR and AS4678 standards.
Fencepac can design and construct retaining walls up to 20 metres high, subject to the wall system, loads, and geotechnical parameters. RSS height is set by the reinforcement design and the available fill and geometry.
