Geogrid Reinforced Soil Wall: Geogrid Reinforced soil retaining walls are internally stabilized systems wherein the fill reinforced with multiple layers ofreinforcement behaves as a coherent composite mass and resists earth pressures from the retained fill and other externally imposed loads.
"Geogrid Reinforced soil retaining walls are internally stabilized systems wherein the fill reinforced with multiple layers of reinforcement behaves as a coherent composite mass and resists earth pressures from the retained fill and other externally imposed loads. Hence the fill material plays an equally important role as the reinforcement and due care has to be exercised in the selection of appropriate type of fill and determination of the properties for design."

Reinforced soil structures (reinforced soil walls and reinforced soil slopes) are mechanically stabilized earth retaining systems that are technically proven and a cost effective alternative to the conventional concrete walls especially for the approach embankment to the bridges / flyovers.
Geogrid Reinforced soil retaining walls are internally stabilized systems wherein the fill reinforced with multiple layers of reinforcement behaves as a coherent composite mass and resists earth pressures from the retained fill and other externally imposed loads. Hence the fill material plays an equally important role as the reinforcement and due care has to be exercised in the selection of appropriate type of fill and determination of the properties for design.
Starting from the idea of concrete steel and from the idea that the soil is self sustainable,in the slope to some extent, it appeared the concept of reinforced soil [6]. Thus, the basic idea of reinforced soil is using reinforcements in the form of bands, bars, wires and sheets inserted between layers of soil and they are likely to take up significant stretching efforts.
However, as in reinforced concrete, they are forming an assembly in which
the reinforcements are located on land in the direction where the soil is solicited on stretching. In this solution, the retaining wall does not add additional efforts: the weight of the material from which the wall is made, the stability being given by the weight of the reinforced soil mass and reinforced efforts stretching over the reinforcements.
The first modern system of soil reinforced was conceived and promoted since 1966 by French engineer Henri Vidal, known as ”Terre Armee” (reinforced soil).
