Terre Armée is a global leader in retaining wall design, being the original creator of the renowned Reinforced Earth® solution.
Retaining walls, earth retention and engineered backfill solutions are necessary on nearly every construction site. The origins of Terre Armée is centered on soil stabilization and pairing our retaining wall solutions with your structure concepts to build a wide range of infrastructure.
Reinforced Earth® MSE wall solution
Terre Armée developed Reinforced Earth® more than 50 years ago. This innovative solution has revolutionized the way retaining walls are designed today. We offer a high-performance and durable solution that is rapid and predictable to install. Reinforced Earth® consists of engineered backfill that is reinforced with a choice of engineered elements, normally geosynthetics or steel. These soil reinforcements are connected to any one of a wide choice of facing elements including concrete panels, steel panels, or wire mesh.
TerraLink® shored MSE wall solution
Shored MSE allows for the construction of retaining walls in geometrically narrow sites. Installation is carried out in front of a stable, existing structure such as a stabilized slope or retaining wall. In such cases when the space required for typical MSE reinforcements and backfill is not attainable, the TerraLink® wall therefore involves connecting the shored MSE mass to the existing structure through a choice of soil reinforcements.
T-Wall® precast modular wall solution
T-Wall®, as its name suggests is a “T” shaped gravity-type retaining wall that is built by assembling modular precast concrete units associated with granular backfill. The perpendicular stems allow for internal stability, providing pullout resistance against the lateral earth pressures exerted on the back of the facing.
TechWall™ precast counterfort wall solution
TechWall™ is a precast retaining wall system that presents the design advantages of counterforts acting as cantilever beams resisting lateral earth pressure. Because the counterforts are optimally reinforced, the moments in the facing panel are minimized and a relatively thin, full-height concrete facing panel may be used.
Post and panel retaining walls
Terre Armée provides planners and builders with two innovative precast concrete post-and-panel wall solutions. These solutions are suited for builders that prefer to install precast ground-mounted posts that allow shallow foundation depths, or also need to build within restrictive rights-of-way or with difficult height clearance limitations.
Retaining walls can be used in various contexts and sectors, and can be used as part of:
- Road and rail retaining structures such as access ramps, vertical retaining walls on the sides of roadways, or embankments
- Bridge abutments and wing walls for crossing structures
- Hydraulic structures such as dams, quays, docks and marinas
- Industrial storage and containment structures
- Landfills and reservoirs
Terre Armée is distinguished among other retaining wall solution providers. Our in-house retaining wall specialists treat each project as unique in its particular challenges. We analyze all project specifics, beginning with your overall site conditions, underlying soil characteristics, space constraints, availability of select backfills, loading conditions, and service life requirements.
Our professional engineers optimize the final design of your wall conceiving the best geometrical and material solutions. We will analyze internal and external stability to meet the long-term service life duration required.
Material Supply Network
The Terre Armée material supply chain consists of a renowned global network of both in-house and outsourced manufacturers and suppliers. We are diligent on furnishing our customers with current registrations and industry certifications of compliance for all aspects of our material supply processes.
Many architectural finishing options are possible to customize your structure, turning your wall into a work of art. Refer to samples in our architectural gallery.
Many precast top-outs are available and can be combined with our retaining walls. We design and furnish precast traffic barriers, trims and copings, and parapets. Our engineers can adapt these structural elements to support handrails, guardrails, swales, lighting supports and catenary fixtures.
Our flagship technique, Reinforced Earth®, is based on the principle of the friction between soil and reinforcements creating a permanent and predictable bond. At the origin of all mechanically stabilized earth (MSE) walls on the market today, we are continuously perfecting this ingenious technique.
A precast retaining wall system, TechWall™ combines the advantages of counterfort with the quality and effectiveness of precast concrete. A great fit for sites with soil bearing capacities allowing for shallow foundations, TechWall™ can also be combined with piling solutions to accommodate different types of soil. Sustainable, cost-effective, and quick to install, TechWall™ may just be the ideal solution for your project needs.
