Shored Reinforced Earth solution for retaining structures in constrained environments

TerraLink is a shored Reinforced Earth solution developed for projects where available space is insufficient for conventional reinforcement lengths. By connecting new reinforced soil structures to existing infrastructure or stable ground, TerraLink enables the construction of retaining structures and slopes in locations where traditional solutions become impractical.

Designed for transportation, urban and infrastructure projects, TerraLink helps engineers reduce excavation requirements, preserve existing structures and optimize available space while maintaining structural performance and long-term durability.

Why TerraLink:

  • Build in constrained environments
  • Preserve existing infrastructure
  • Reduce excavation and earthworks
  • Maintain structural continuity and performance

Expanding infrastructure where conventional solutions do not fit

Infrastructure upgrades frequently need to be performed adjacent to existing structures, within narrow corridors or in environments where conventional reinforcement lengths cannot be accommodated.

Widening roads, railways, ramps or platforms often requires solutions capable of minimizing disruption while preserving existing infrastructure. In many cases, demolition, extensive excavation or reconstruction programmes can significantly increase costs, environmental impact and project duration. Common project challenges:

  • Insufficient space for standard reinforcement lengths
  • Existing infrastructure constraints
  • Road and ramp widening projects
  • Limited excavation opportunities
  • Maintaining traffic and operations during construction
  • Steep terrain and rocky environments
  • Preservation of existing infrastructure
  • Project schedule and cost optimization

Designed to connect new structures to existing infrastructure

TerraLink extends the capabilities of Reinforced Earth technique by allowing reinforced soil structures to be connected directly to existing structures or stable ground. Rather than relying solely on conventional reinforcement lengths, TerraLink transfers loads through engineered connection solutions adapted to project-specific conditions.

The solution can be applied to both Reinforced Earth walls and abutments, and Reinforced Earth slopes, creating continuity between existing and new infrastructure while limiting demolition and excavation requirements. Depending on design conditions, connections can be created through friction link or direct link approaches.

This design flexibility allows TerraLink to address some of the most complex infrastructure constraints, including urban widening projects, steep topography and rehabilitation programmes where preserving existing structures is a key project objective.

Key technical capabilities:

  • Shored Reinforced Earth technique
  • Friction link connection
  • Direct link connection
  • Integration with Reinforced Earth walls and slopes
  • Reduced reinforcement length requirements
  • Adaptation to constrained geometries
  • Compatibility with soil nails and anchors
  • Tailored engineering for complex conditions

Built for infrastructure constrained by space

TerraLink enables infrastructure expansion where conventional retaining solutions would require significant demolition, extensive excavation or major disruption to existing infrastructure.

  • Build where space is limited

Allows retaining structures to be constructed where conventional reinforcement lengths cannot be accommodated.

  • Preserve existing infrastructure

Reduces the need for demolition, reconstruction and major modifications.

  • Minimize construction disruption

Helps maintain traffic flow and operational continuity during implementation.

  • Reduce project footprint

Limits excavation volumes and associated environmental impacts.

  • Optimize delivery costs

Reduces earthworks, construction duration and material requirements.

Available connection approaches

  • Friction link

The new reinforced structure is connected through overlapping reinforcement elements that develop load transfer through friction mechanisms. This approach is adapted to many constrained widening applications.

  • Wall extensions

Suitable for widening and extending existing retaining wall structures while maintaining structural continuity.

  • Slope extensions

Can be integrated into reinforced slope structures to optimize limited available space.

  • Direct link

Loads are transferred through engineered direct structural connections between the new structure and the existing one. This solution is developed for projects requiring specific structural continuity requirements.

  • Integration with anchors and soil nails

Additional stabilization measures can be incorporated when required by project conditions.

  • Project-specific design

Every TerraLink solution is tailored according to geometry, existing infrastructure conditions and operational requirements.
