How to overcome tight spaces in infrastructure projects
As infrastructure evolves, space is increasingly limited—but the need for widening roads, railways, and bridges continues to grow, be it for urban infrastructure projects or mine sites. Geoquest’s TerraLink® is a proven shored MSE (Mechanically Stabilised Earth) retaining wall solution engineered to meet this challenge.
Built directly in front of an existing retaining wall, soil nail wall, rock face, or stabilised slope, a TerraLink® shored MSE wall uses the existing structure to reduce lateral earth pressure—enabling new earth-retaining structures where a traditional base width is not possible.
How TerraLink® Works
When there isn’t enough space behind a proposed wall to build a conventional MSE structure with a trapezoidal base, TerraLink® steps in. This innovative system links new reinforced earth walls to existing structures, using a bin-wall configuration that incorporates primary and secondary soil reinforcements.
Each TerraLink® solution is custom-designed based on a site’s conditions. Our engineers assess the geometry, condition, and remaining service life of the existing structure to ensure it can support the intended reduction in lateral earth pressure over the life of the new build.
Designed for Complex Projects
Whether it’s a road or rail widening, a bridge abutment extension, or an upgrade to a corridor where space is restricted, TerraLink® provides a highly adaptable and cost-effective solution. It’s particularly effective when the existing structure retains much of its original strength but needs to be improved to accommodate new loads or traffic volumes.
Key Features of TerraLink® Shored MSE Walls
- Ideal for Tight Construction Sites: Overcomes spatial limitations by building directly in front of an existing structure.
- Reduces Excavation and Fill: Efficient design cuts down on heavy earthwork and material costs.
- Dual Reinforcement System: Uses alternating or directly linked reinforcement layers to connect the new structure to the existing one.
- Versatile Facing Options: Precast concrete panels or welded wire mesh for a tailored finish.
- Compatible with TerraNail™: Our engineered soil nail system for added structural stability.
Proven Performance by Geoquest
Shored MSE wall design is a specialised engineering discipline, and Geoquest has led the way in developing and applying these systems throughout Australia. Our TerraLink® solution is built on decades of technical expertise, rigorous structural analysis, and a deep understanding of site-specific challenges.
If you’re looking to safely expand infrastructure with minimal disruption, shored MSE walls offer the precision, flexibility, and cost-efficiency you need.
