How it Works

Protective Structures

Reinforced Earth® has been used to protect against explosions, avalanches and earthquakes all around the world.


Being a mass gravity structure, Reinforced Earth® is capable of absorbing huge amounts of kinetic and thermal energy with minimum distortion.

From temperatures of -160°C for liquid natural gas up to a constant flame temperature of about 1100°, Reinforced Earth® behaves extremely well under extreme conditions.

Reinforced Earth® has been adopted for many protective structures in the military. As a system, it offers the advantage of forming a massive flexible structure that can absorb a high level of energy without being fragile.

One common military application, for Reinforced Earth® in Australia, is as a barrier used to protect highly trained personnel and expensive military hardware (for example; fighter planes) from potential blast propagation on our RAAF bases.

Bomb test

The facing panels of these structures are precast without steel reinforcement so that in the event of a blast, the facing breaks up into small pieces. Being unreinforced, these small pieces don't travel as far as larger pieces that would otherwise be held together by certain steel elements.


Furthermore; bomb tests in Australia and overseas, by government and private organisations, highlight the disturbing reality that flying steel shrapnel is virtually the same as bullets. Therefore, it is advantageous to reduce steel reinforcement to an absolute minimum.


The Reinforced Earth Company (Australia) has strategically built Missile Barriers and Traverses on 3 RAAF bases in Australia, limiting the damage of any explosion.
