Shored MSE structures (SMSE) are now widely sought by engineers that are challenged to widen or rehabilitate existing infrastructure.
Our innovative solution is TerraLink, developed by Geoquest, this solution solves these challenges to build new earth-retained structures that front existing structures where limited room for expansion is available.
Geoquest engineers have pioneered this innovative solution to link a new structure to an existing structure. With TerraLink, you can build widenings or additions to link an added structure to the face of a soil-nail wall, an existing concrete retaining wall, or a natural feature such as sloped terrain that are allowing only a narrow space for the necessary soil reinforcements and backfill.
Space constraints
Infrastructure widening and rehabilitation
Costs and environmental impact reduction
Road and railway widenings
The continuous increase in road and railway traffic in urban areas renders existing infrastructure as under-dimensioned. Infrastructure widening with structure additions using our TerraLink SMSE solution is necessary to loosen traffic bottlenecks and stabilize existing structures.
Earth shoring
TerraLink is a cost-effective way for building a conventional earth-retained structure or shoring system in restrictive proximity to an existing slope or structure. Typical design conceptions involve significant earthwork through excavation and excessive fill, and replacements. By lowering these high costs, TerraLink is an excellent solution.
The TerraLink connections
Our solution is intended to link an existing structure with the new TerraLink structure. These structures are designed with either one, or a combination of two different methods for linking:
- Friction link
Alternating layers of soil reinforcements, each layer connected to one or the opposing surface
- those being solely connected to the back face of the new structure
- those being solely connected to the face of the existing structure.
- Direct link
All soil reinforcement connecting the two extremities are structurally linked directly to one another.
One or both, friction-link or direct-link connections could apply to your project.
Design approach
Key in designing the TerraLink configuration, Geoquest engineers will assess the conditions of the existing structure(s). We closely analyze the origin (existing MSE, soil nail wall, sloped terrain, bedrock, etc.), as it is important to evaluate the stability of the as-built environment. We consult with you on internal and external stability in support of the new, reconfigured structure, including revised load conditions and extended service life.
Our solutions allows:
Space optimization
Works in tight areas without requiring large backfill or reinforcement zones.
Cost efficiency
Reduces excavation, material use, and overall construction expenses.
Environmental sustainability
Minimizes land disturbance and lowers ecological impact compared to traditional methods.
Structural reliability
Ensures stability and durability for infrastructure upgrades and expansions.
Faster project delivery
Simplifies construction processes, enabling quicker completion with less disruption.
