Reinforced Earth pioneer solutions for retaining walls and slopes ensuring sustainable, adaptable and optimized structures
Geoquest invented in the 1960s the Reinforced Earth technique that is based on a simple concept. As originally conceived by its inventor, French architect and engineer Henri Vidal, the interplacing of soil and reinforcements develops friction at the points of contact between the two, resulting in a permanent and predictable bond and creating a unique composite construction material.
For more than six decades, the Reinforced Earth technique has set the global standard for mechanically stabilized earth (MSE) structures. Continuously refined through thousands of projects worldwide, this technique combines engineered backfill, high‑performance soil reinforcements, and modular facing elements to create durable, cost‑efficient, and resilient retaining structures.
Geoquest has played a pioneer role in advancing this technique, delivering sustainable and versatile solutions across all infrastructure projects.
