In 1963, Henri Vidal, a French engineer, developed a new composite material using earth as a raw material.
Easy-to-use, the Reinforced Earth® (
Terre Armée) technology quickly took hold as an ideal reinforced backfill solution, spawning the development of a company with offices across the five continents in just a few decades.

Reinforced Earth® concentrates an unequalled combination of expertise and accumulated experience in the fields of soil-structure interaction and engineered backfills.
Our expansive portfolio of techniques applies to a wide range of structures for an extended array of market segments: roads and motorways, environment, railways, hydraulic works, mining, industry, energy, commercial, housing or military.


At the origin of mechanically stabilized earth structures, Reinforced Earth® has an active presence on the five continents. Worldwide leader in soil reinforcements, we are proud to build on the legacy of Henri Vidal’s Reinforced Earth® invention and call ourselves The Original.
