For nearly fifty years, Terre Armee companies have furnished designs and materials to owners and contractors for the construction of a variety of military facilities and structures.

These have included:

  • Ammunition igloos and storage bunkers
  • Blast barricades
  • Personnel protection facilities
  • Weapons testing facilities
  • Rocket launching platforms
  • Radiation and RFI shielding
  • Forced entry fences and ballistic shields
  • Military roads and bridges
  • Sea walls and wharf docks

Our history working with military agencies

From inception, Reinforced Earth® retaining walls were figured as a logical extension for constructing critical structures to protect against explosions, fire, and bombardment. The technology’s performance had already been established in many previous applications. Ordinary earthen structures offer advantages in protective barrier applications. However, Reinforced Earth® provides the additional benefit of vertical revetments, which not only minimize ground area requirements, but also increase the degree of protection.

Reinforced Earth® has proven to be a highly stable explosion barrier that impedes the propagation of a blast at ground level and absorbs high levels of energy due to its tolerance for deformation. Because it is resistant to multiple fracturing, Reinforced Earth® tends to minimize the dispersal of debris during an explosion while maintaining high levels of resistance to thermal shock.

The use of Reinforced Earth® walls for protective military structures was rapidly developed through a series of full-scale military testing starting in the middle 1970’s. This research and development continues even today, for example in developing state of the art solutions for designing and furnishing special Terre Armee MSE “bund” structures for dissipation of blast pressures and projectile impact.

Development, approvals and certifications

A similar research and development trajectory for the TechSpan® precast concrete arch technology beginning in the late 1990’s also continues today. In 1999, both Reinforced Earth® and TechSpan® was approved in combination by the US Department of Defense Explosives Safety Board (DDESB) for construction of standard oval arch earth covered storage magazines, or ECMs. TechSpan’s 3-hinge staggered arrangement integrates the arch’s backfill into the FEM model giving TechSpan® the inertia and flexibility to absorb explosive energy while remaining structurally intact.

In 2020 this standard design was improved with options for the owner’s engineer or building contractor to select optional geosynthetic soil reinforcements and fiber concrete reinforcements in lieu of steel reinforcements.

Other Terre Armée military applications include structures built to support roadways, bridges, rail spurs, and waterways at these military installations.

Benefits

Predictable performance

Predictable performance

Full-scale testing, actual event forensics data, and numerical modelling of Terre Armée protective structures support and validate the predicted performance of your application.

Cost, Quality, and Design Flexibility

Cost, Quality, and Design Flexibility

Lower in completed cost than alternative soil-reliant structures. Owners and builders can select between steel or geosynthetic reinforcements for both the soil and concrete.

Sustainability

Sustainability

Complete methodology is adaptable for remote area constraints, light equipment, and small working crews. Structures can be designed as permanent or temporary with dismantling and re-use possible.
