Terre Armée in India has forged an inimitable level of expertise to provide unique and bespoke solutions to a wide array of market segments. The techniques developed by Terre Armée are particularly suited to the following segments:
Roads & Motorways
Roads & Motorways
From its invention, Reinforced Earth® has been used for building road and motorway structures and bridge abutments. This technology is widely used for these structures because they require short construction time and minimum right of way so traffic disruption is considerably reduced. Reinforced Earth® was first used to build single-tier and multi-tier retaining walls alongside roads.
It is also used in many other types of applications for road structures:
• Viaduct access ramps • Complex multi-level interchanges
• Structures on uneven terrain • Road widening
• Bridge abutments
The retaining structures alongside railway lines must be perfectly capable of absorbing the vibrations caused by passing trains and supporting the high stresses generated by accelerating and decelerating trains. Reinforced Earth® is a material ideally suited for use in rail systems, including structures for high speed lines. The technologies used are the same as roads; however, the designs are modified to take into account specific requirements concerning surcharges or coefficients of safety, especially for high speed trains. TechSpan® and TechBox™ cut and cover solutions are also used for railway projects.
Rivers & Waterways
Rivers & Waterways
Numerous Terre Armée hydraulic structures have been constructed throughout the world, including retaining walls for coastal roads or alongside rivers, quay walls, breakwaters, dykes, spillways and reservoirs. The technology is easily adapted to these complex situations and has performance characteristics that have made it universally accepted. The wide choice of soil reinforcement materials associated with the Reinforced Earth® system allows this technique to be used for all types of water conditions, fresh, brackish or saline. TechRevetment® is often used for erosion protection measures for river and waterway projects.
Ports & Coastal Works
Ports & Coastal Works
Terre Armée delivers best-fit solutions and provides end-to-end support in projects that need to conform to the specific requirements for harbour and coastal structures. Terre Armée technology has been used for over 40 years to build marine structures either on coastlines or in harbours. The design and selection of construction materials used in marine environments must reflect the risks inherent in this special environment. TerraDyke™ technology is used to construct cores of dykes and breakwaters.
River structures are designed and built to resist the combined forces of water and water borne debris, which can be highly destructive during and after storms or floods. Our structures also resist other environmental stresses such as strong currents. Reinforced Earth® structures combined with proper backfill materials ensure adequate drainage, especially if the structure may be subjected to sudden rapid draw down and other variations in water levels. In addition to erosion protection, TechRevetment® is used for lining bed and banks of channels and canals.
Demonstrating its versatility, the Terre Armée technique has been used for the construction of reservoirs for potable water. Concrete segmental panels were combined with a UV resistant lining to provide water tightness. The GeoMega® system associating fully synthetic connections and reinforcements is well adapted to such structures, especially when chemically aggressive materials are sourced for the backfill.
Oil & Gas
Oil & Gas
Terre Armée has been an active partner from upstream to downstream delivering infrastructure solutions that are vital for your Oil & Gas projects. Together with project stakeholders, we rise to the challenge of building structures that allow access and workability for extraction, storage and production.
The excellent adaptability of Terre Armée technologies means that they are the ideal solution for meeting the requirements of structures in the power industry, which need to be capable of withstanding high loads, vibrations, variations in temperature and electrical shocks. Safety is one of the top priorities at such sites and can be ensured by building Terre Armée structures with the ability to resist severe thermal and physical conditions, such as accidental fires lasting several days in storage silos or extreme differences in temperature, from -160°C for liquefied natural gas to 1,100°C for flame temperatures.
The excellent adaptability of Terre Armée technologies mean that they are the ideal solution for meeting the requirements of structures in industry, which need to be capable of withstanding high loads, vibrations, variations in temperature and electrical shocks. Reinforced Earth® retaining barricades have pioneered the supply of secondary containment walls for oil and liquids in natural gas storage tanks.
Able to blend harmoniously with the landscape, Terre Armée adapts and integrates while providing the benefits of its strength and protection against natural risks. The most successful civil engineering projects are those combining excellent performance with a sleek design. Even with smaller scale projects, clients, architects, engineers and landscapers go to great lengths to demonstrate their professional expertise by designing structures that blend into their environment and enhance their surroundings.
The architectural flexibility of Terre Armée technology is clearly apparent when used for land development and housing in close liaison with architects, city planners and landscapers. Reinforced Earth® Facings come in a wide variety of finishes and patterns. Welded wire mesh facings represent a durable solution for building reinforced embankments that blend seamlessly into the environment, either by covering with vegetation or a stone finish.
Airports are often located in areas where their expansion is made complex by the lack of space or the presence of hills, coastal areas or natural water channels. Reinforced Earth® enables reduction in land use, allowing expansion in even restricted environments. Terre Armée technology is ideal for use in airport infrastructure for which the technical constraints are multiple: high loads, significant wall heights, and speed of installation imposed in order to maintain flight operation.
Terre Armée plays a role in enhancing the appearance and design of our environment. Some of its applications can even protect human life. Terre Armée technologies offer a number of advantages for curbing environmental impact on the sites at which they are being used:
- Economic use of materials
- Reduced impact and footprint on the site during construction
- Fewer CO2 emissions
- Use of natural or recycled materials
Terre Armée retaining barricades are used in military bases to protect explosives depots, underground bunkers and storage silos. Protective walls are designed for human protection and contain the spread of damage to adjacent structures.
Due to its high strength and its ability to support dynamic loading, TechSpan® is a reliable, efficient, quick and cost effective solution for creating ammunition depots, shelters and tunnels in liaison with Reinforced Earth® structures.
Sports & Leisure
Sports & Leisure
Thanks to its excellent adaptability, Terre Armée technology provides an ideal answer to the design requirements of sports and leisure structures: climbing walls, racetracks, stadiums and waterproof retaining structures.
By building stable walls capable of bearing heavy loads with little settlement, Reinforced Earth® can be extended to abutments directly supporting bridge decks.
These structures are located at both ends of a bridge and clearly spotlight the technology's unique capabilities. Although the general principle of Reinforced Earth® remains the same, the settlement restrictions, loads and stresses involved with this type of structure are extremely high.
Bridges constructed in front of water bodies and rivers can be protected against erosion by using the TechRevetment® technology.
Terre Armée Group companies deliver tailored solutions and provide end-to-end support for critical structures like dams, that need to conform to the highly technical requirements. Strengthening under designed dams or century old dams built, for example, of stone and cyclopic concrete or masonry concrete can be achieved by improving their stability by means of Terre Armée techniques. High-water spillways of Reinforced Earth® walls, with sloped facing abutting the downstream face of the existing structures, allow adequate overflow capacity. Erosion protection and underwater scour can be achieved with TechRevetment® technology.
Mother Nature may sometimes reveal her extremely dangerous side, causing heavy loss of life, injury and extensive damage to property. Drawing strength from resilience and ductility, Terre Armée structures are designed to minimize damage in case of natural disasters such as:
• Avalanches • Landslides
• Earthquakes • Rockfalls and slope failures • Floods • Tsunamis
• Mudflows • Lava flows
