Stone Strong® retaining wall systems can be designed using a range of reinforcement methods to accommodate increased wall heights, surcharge loads, poor ground conditions, bridge structures, transport infrastructure, and constrained construction sites. By combining the structural mass of Stone Strong precast concrete blocks with proven reinforcement technologies, engineers can deliver economical, durable, and high-performance retaining wall solutions.

Whether the project requires a mechanically stabilised earth (MSE) wall, steel strip reinforcement, or tieback anchor systems, Stone Strong provides the flexibility to meet demanding geotechnical and structural requirements.

Mechanically Stabilised Earth (MSE) Walls

Stone Strong MSE walls combine large precast concrete facing units with geosynthetic or steel reinforcement extending into the retained soil mass. The reinforced soil zone acts as a gravity structure, allowing walls to achieve significant retained heights while maintaining cost-effective construction.

Benefits

• Suitable for high retaining walls exceeding traditional gravity wall limitations
• Reduces foundation loads compared with conventional concrete structures
• Accommodates differential settlement
• Utilises locally available backfill materials where suitable
• Rapid installation with minimal site disruption
• Ideal for bridge abutments, transport corridors, commercial developments, and embankments

Tieback Anchor Systems

Where space constraints prevent the use of traditional reinforced soil zones, Stone Strong walls can be integrated with tieback anchor systems. Anchors are drilled into competent ground behind the wall and connected to the retaining structure to provide additional lateral resistance.

Benefits

• Ideal for restricted sites and property boundaries
• Minimises excavation requirements
• Suitable where reinforcement lengths are limited
• Allows construction adjacent to existing infrastructure
• Effective for steep excavations and temporary works
