Reinforced Earth

The worldwide acceptance and utilization of Reinforced Earth® known as Terra Armée® make it one of the most significant civil engineering developments in the last decades all over the World.

Reinforced Earth Company (REAS) is recognized as the inventor and a market leader in Mechanically Stabilized Earth (MSE) retaining structures. We design, supply and advise on the installation of two major types of prefabricated construction systems: Reinforced Earth retaining structures( reinforced earth, geomega, terratrel and geotrel walls) and TechSpan® precast concrete arch systems.

The GeoMega™ MSE retaining walls are coherent gravity structures engineered to resist specific loading requirements. The primary components of a GeoMega wall consist of alternating layers of granular backfill, and high-tenacity polyester based soil reinforcement or “geostrap” to which a modular precast concrete facing is attached.

TerraTrel-Geotrel wire-faced MSE wall system provides all the design advantages of traditional Reinforced Earth at a reduced cost. The primary components of a TerraTrel-Geotrel wall consist of alternating layers of granular backfill, and steel strips or high-tenacity polyester based soil reinforcement or “geostrap” to which a wire-facing is attached.

Precast Arch Systems (Techspan) Our modular two-pin or three-pin precast concrete arch systems are simple and quick to erect. Suitable for highways, rail, mining and hydraulic applications.

A variety of applications such as retaining walls in fill and cut sections, abutments, water structures and railways have been used widely in many countries as well as in Turkey since 1988. Reinforced Earth® walls have been built on the Tarsus-Adana-Gaziantep, Izmir-Cesme, Kinali-Sakarya, Toprakkale-Iskenderun, Gerede-Gumusova motorways and lately on the Izmir-Istanbul Highway. More than 1.200.000 sqm of Reinforced Earth® walls have been built in national highways, motorways, intersections of metropolitan municipalities and private sector projects in Turkey.

A local Turkish company was incorporated in 1998 under the title of "Reinforced Earth® Insaat Proje ve Tic A.S." by the foreign shareholder, the Freyssinet Group who is the inventor and developer of the Reinforced Earth® technology.

Our company develops specific projects and realizes Reinforced Earth® applications in accordance with the international standards and with the technical support of Soletance Freyssinet Group. Our company offers supply of project design, Feasibility Studies, Preliminary Design, Final Design, Onsite Construction, Project Management , Design-Build, material, application and technical supervision by using local sources on turnkey basis.
